Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation In the opinion of management, the accompanying unaudited Consolidated Financial Statements of Schmitt Industries, Inc. (the “Company”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission and contain all adjustments, consisting only of normal recurring adjustments, necessary to present fairly its financial position as of February 29, 2020 and its results of operations and its cash flows for the periods presented. The Consolidated Balance Sheet at May 31, 2019 has been derived from the Annual Report on Form 10-K 10-K As described in Note 8, the Company sold the Schmitt Dynamic Balance Systems (“SBS”) business line on November 22, 2019. After the sale of the SBS business, based on the types of products and services sold, and an analysis of how the Chief Operating Decision Makers review, manage and are compensated, the Company determined that it operates as one segment. Principles of Consolidation These Consolidated Financial Statements include those of the Company and its wholly owned subsidiaries: Schmitt Measurement Systems, Inc. and Schmitt Industries (Canada) Limited. All significant intercompany accounts and transactions have been eliminated in the preparation of the Consolidated Financial Statements. Reclassification Certain amounts in the prior period Consolidated Balance Sheet have been reclassified to conform to the presentation of the current period. Certain amounts in the prior periods presented have been reclassified to conform to the current period financial statement presentation. These reclassifications have no effect on previously reported net income (loss). Revenue Recognition The Company determines the amount of revenue it recognizes associated with the transfer of each product or service. For sale of products or delivery of monitoring services to all customers, each transaction is evaluated to determine whether there is approval and commitment from both the Company and the customer for the transaction; whether the rights of each party are specifically identified; whether the transaction has commercial substance; whether collectability from the customer is probable at the inception of the contract and whether the transaction amount is defined. If a transaction to sell products or provide monitoring services meets all of the above criteria, revenue is recognized for the sales of product at the time of shipment or for monitoring services at the completion of the month in which monitoring services are provided. The Company incurs commissions associated with the sales of products, which are accrued and expensed at the time the product is shipped. These amounts are recorded within general, administration and sales expense. The Company also incurs costs related to shipping and handling of its products, the costs of which are expensed as incurred as a component of cost of sales. Shipping and handling fees billed to customers, which are recognized at the time of shipment as a component of net revenues, were $21,066 and $24,242 for the nine months ended February 29, 2020 and February 28, 2019, respectively. Cash, Cash Equivalents and Restricted Cash The Company generally invests its excess cash in money market funds. The Company’s investment policy also allows for cash to be invested in investment grade highly liquid securities, and the Company considers securities that are highly liquid, readily convertible into cash and have original maturities of less than three months when purchased to be cash equivalents. The Company’s cash consists of demand deposits in large financial institutions and money market funds. At times, balances may exceed federally insured limits. Restricted cash consists of an amount held in escrow related to the sale of the balancer business segment, as described in Note 8. Once certain events are complete, the restrictions on this cash payment will be released. The following table provides a reconciliation of cash and cash equivalents and restricted cash as reported within the Consolidated Balance Sheets as of February 29, 2020 and May 31, 2019 t Statement of Cash Flows for the nine months ended February 29, 2020 February 29, 2020 May 31, 2019 Cash and cash equivalents $ 10,544,255 $ 1,467,435 Restricted cash 420,000 — Total cash, cash equivalents and restricted cash shown in the Consolidated Statement of Cash Flows $ 10,964,255 $ 1,467,435 The amounts in m m Accounts Receivable The Company maintains credit limits for all customers based upon several factors, including but not limited to financial condition and stability, payment history, published credit reports and use of credit references. Management performs various analyses to evaluate accounts receivable balances to ensure recorded amounts reflect estimated net realizable value. This review includes using accounts receivable agings, other operating trends and relevant business conditions, including general economic factors, as they relate to each of the Company’s domestic and international customers. In the event there is doubt about whether a customer account is collectible, a reserve is provided. If these analyses lead management to the conclusion that a customer account is uncollectible, the balance will be directly charged to bad debt expense. The allowance for doubtful accounts was $99,442 and $36,826 as of February 29, 2020 and May 31, 2019, respectively. Inventories Inventories are valued at the lower of cost or net realizable value with cost determined on the average cost basis. Costs included in inventories consist of materials, labor and manufacturing overhead, which are related to the purchase or production of inventories. Write-downs, when required, are made to reduce excess inventories to their net realizable values. Such estimates are based on assumptions regarding future demand and market conditions. If actual conditions become less favorable than the assumptions used, an additional inventory write-down may be required. As of February 29, 2020 February 29, 2020 May 31, 2019 Raw materials $ 116,814 $ 347,095 Work-in-process 536,513 376,375 Finished goods 403,757 517,662 $ 1,057,084 $ 1,241,132 Property and Equipment Property and equipment are stated at cost, less depreciation and amortization. Depreciation is computed using the straight-line method over estimated useful lives of three to seven years for furniture, fixtures, and equipment; and twenty-five years for buildings and improvements. Expenditures for maintenance and repairs are charged to expense as incurred. As of February 29, 2020 February 29, 2020 May 31, 2019 Land $ 299,000 $ 299,000 Buildings and improvements 1,840,025 1,814,524 Furniture, fixtures and equipment 396,986 498,476 2,536,011 2,612,000 Less accumulated depreciation (1,876,748 ) (1,858,593 ) $ 659,263 $ 753,407 Depreciation expense for the nine months ended February 29, 2020 Lease Accounting The Company determines if an arrangement is a lease or a service contract at inception. Where an arrangement is a lease the Company determines if it is an operating lease or a finance lease. Subsequently, if the arrangement is modified the Company reevaluates the classification. Buildings leased to others under operating leases are included in property, plant and equipment. See Note 6. Intangible Assets Amortizable intangible assets, which include purchased technology and patents, are amortized over their estimated useful lives ranging from five to seventeen years. As of February 29, 2020 $2,085,362 and Amortization expense for both the nine months ended February 29, 2020 . Customer Deposits and Prepayments Customer deposits and prepayments consists of amounts received from customers as prepayments for orders that have been received and have been produced but have not yet shipped, credit balances for items returned by customers for which refunds have not yet been provided and deposits made by customers in advance of production. Use of Estimates The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS [Abstract]
Recently Issued Accounting Pronouncements	NOTE 2: RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In February 2016, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard on leasing. The new standard requires companies to record most leased assets and liabilities on the balance sheet, and also proposed a dual model for recognizing expense. The Company adopted the standard as of June 1, 2019, with retroactive reporting for prior periods (the comparative option). Adoption of these accounting changes did not have a material impact on the Consolidated Financial Statements. In January 2017, the FASB issued a new accounting standard which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This guidance was effective for the Company beginning in 2019. Adoption of these accounting changes did not have a material impact on the Consolidated Financial Statements. In May 2017, the FASB issued a new accounting standard which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in ASC Topic 718. Under the guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. This guidance was In June 2018, the FASB issued a new accounting standard which provides guidance that expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees.

Stock Options And Stock-Based Compensation	NOTE 3: STOCK OPTIONS AND STOCK-BASED COMPENSATION Stock-based compensation includes expense charges for all stock-based awards to employees and directors granted under the Company’s stock option plan. Stock-based compensation recognized during the period is based on the portion of the grant date fair value of the stock-based award that will vest during the period, adjusted for expected forfeitures. Compensation cost for all stock-based awards is recognized using the straight-line method. Stock Options The Company uses the Black-Scholes option pricing model as its method of valuation for stock-based awards. The Black-Scholes option pricing model requires the input of highly subjective assumptions, and other reasonable assumptions could provide differing results. These variables include, but are not limited to: • Risk-Free Interest Rate. • Expected Life. pre-vesting • Expected Volatility. • Expected Dividend Yield. • Expected Forfeitures. pre-vesting There were no options granted during the nine months ended February 29, 2020. At February 29, 2020, the Company had outstanding stock options to purchase 22,500 shares of Common Stock all of which are vested and exercisable with a weighted average exercise price of $1.70.

Market-based restricted stock units are contingent on continued service and vest based on the 15-day The lattice model utilizes multiple input variables that determine the probability of satisfying the market conditions stipulated in the award and calculates the fair value of each restricted stock unit. The Company used the following assumptions in determining the fair value of the restricted stock units: Year Ended May 31, 2019 Expected stock price volatility 50.1% - 57.5% Expected dividend yield 0.0% Average risk-free interest rate 2.55% - 2.98% During the nine months ended February 29, 2020, five During the nine months ended February 29, 2020, 62,780 service-based restricted stock units were granted and 46,863 immediately vested on the date of the grants.

Earnings Per Share [Abstract]
Weighted Average Shares and Reconciliation	NOTE 4: WEIGHTED AVERAGE SHARES AND RECONCILIATION Basic net income (loss) per share is computed using the weighted average number of shares of Common Stock outstanding. Diluted net income (loss) per share is computed using the weighted average number of shares of Common Stock outstanding, adjusted for dilutive incremental shares attributed to outstanding options to purchase Common Stock and restricted stock units vested but not issued. Common stock equivalents for stock options are computed using the treasury stock method. In periods in which a net loss is incurred, no common stock equivalents are included since they are antidilutive and as such all stock options outstanding are excluded from the computation of diluted net loss in those periods. For the three and nine months ended February 29, 2020, potentially dilutive securities consisted of options of 22,500 shares of Common Stock at $1.70 per share. Of these potentially dilutive securities, none of the shares of Common Stock underlying the options are included in the computation of diluted earnings per share because the Company incurred a net loss from continuing operations. In periods when a net loss is incurred in continuing operations, no Common Stock equivalents are included in the calculation of diluted net income or loss from discontinued operations or overall Company net income or loss since they are antidilutive. As such, all stock options outstanding are excluded from the computation of diluted net income in those periods.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 5: INCOME TAXES The Company accounts for income taxes using the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Management continues to review the level of the valuation allowance on a quarterly basis. There can be no assurance that the Company’s future operations will produce sufficient earnings to allow for the deferred tax asset to be fully utilized. The Company currently maintains a full valuation allowance against net deferred tax assets. Each year the Company files income tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the taxing authorities. Positions challenged by the taxing authorities may be settled or appealed by the Company. As a result, there is an uncertainty in income taxes recognized in the Company’s financial statements in accordance with ASC Topic 740.The Company applies this guidance by defining criteria that an individual income tax position must meet for any part of the benefit of that position to be recognized in an enterprise’s financial statements and provides guidance on measurement, de-recognition, Other long-term liabilities related to tax contingencies were $0 as of both February 29, 2020 and May 31, 2019. Interest and penalties associated with uncertain tax positions are recognized as components of the “Provision for income taxes.” The liability for payment of interest and penalties was $0 as of February 29, 2020 and May 31, 2019. Several tax years are subject to examination by major tax jurisdictions. In the United States, federal tax years ended May 31, 2016 and after are subject to examination.

Discontinued Operations	NOTE 8: DISCONTINUED OPERATIONS On October 10, 2019, the Company entered into an agreement (“Purchase Agreement”) to sell the Schmitt Dynamic Balance Systems (“SBS”) business line to Tosei Engineering Corp. and Tosei America, Inc. (collectively “Tosei” or Buyer) for a purchase price of $10,500,000 in cash. The transaction closed on November 22, 2019 and included certain assets held by the U.S. parent company and all the outstanding stock of the UK subsidiary, Schmitt Europe Limited. As a result, the financial position, results of operations, and cash flows relating to our SBS business line are reported as discontinued operations in the accompanying financial statements. The consideration included $9,940,000 in unrestricted cash from the Buyer at closing, plus $420,000 to be placed into an escrow account, net of $140,000 in minimum cash settled via the funds flow at closing. Remaining escrow funds become unrestricted after certain events are completed and after one year from closing. The Purchase Agreement requires an adjustment to purchase price after closing based on the difference between (a) the calculated amount of working capital at closing and (b) the target working capital of $4,200,000. The closing working capital calculation resulted in $107,000 in net proceeds paid from Buyer to Seller in February 2020. In connection with the Purchase Agreement, the Company entered into a Transition Service Agreement (“TSA”) with the Buyer during the transition of certain accounting and treasury processes. The Company has collected appro ximately cash belonging to the Buyer via the TSA that is included in the cash and cash equivalents, accounts receivable, and other accrued liabilities balances at February 29, 202 0 The following table summarizes the consideration and gain recognized in the nine mo nths Purchase Price $ 10,500,000 Cash in SEL 69,157 Less: Net assets sold $ 4,383,157 Minimum cash 140,000 Transaction fees 453,287 Release of cumulative translation adjustment from OCI 455,848 Plus or minus: Closing adjustments 107,000 Pre-tax $ 5,243,865 Income taxes 80,831 Gain on sale, net of income taxes $ 5,163,034 The following are the carrying amounts of assets and liabilities classified as held for sale and included as a part of discontinued operations: February 29, 2020 May 31, 2019 Accounts receivable, net $ — $ 1,365,114 Inventories — 3,777,913 Prepaid expenses — 49,357 Current assets held for sale $ — $ 5,192,384 Property and equipment, net — 85,967 Noncurrent assets held for sale $ — $ 85,967 Accounts payable $ — $ 393,773 Accrued commissions — 128,453 Accrued payroll liabilities — 127,124 Customer deposits and prepayments — 109,860 Other accrued liabilities — 89,939 Current liabilities held for sale $ — $ 849,149 Net assets held for sale $ — $ 4,429,202 The following is a composition of the line items constituting income from discontinued operations: Three Months Ended , Nine Months Ended , Februar y 29, Februar y 2 8 Februar y 29, Febraury 2 8 Net revenue $ — $ 1,961,638 $ 4,343,008 $ 6,501,447 Cost of revenue — 1,364,540 2,374,251 4,162,257 Gross profit — 597,098 1,968,757 2,339,190 Operating expenses: General, administration and sales — 681,125 1,252,222 2,069,326 Research and development — 15,036 35,920 63,790 Total operating expenses — 696,161 1,288,142 2,133,116 Operating income — (99,063 ) 680,615 206,074 Other expense, net — 52,236 (140,923 ) (76,793 ) Income before income taxes — (46,827 ) 539,692 129,281 Provision for income taxes — 4,399 7,589 12,899 Net income from discontinued operations, before gain on sale, net of tax $ — $ (51,226 ) $ 532,103 $ 116,382

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In the opinion of management, the accompanying unaudited Consolidated Financial Statements of Schmitt Industries, Inc. (the “Company”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission and contain all adjustments, consisting only of normal recurring adjustments, necessary to present fairly its financial position as of February 29, 2020 and its results of operations and its cash flows for the periods presented. The Consolidated Balance Sheet at May 31, 2019 has been derived from the Annual Report on Form 10-K 10-K As described in Note 8, the Company sold the Schmitt Dynamic Balance Systems (“SBS”) business line on November 22, 2019. After the sale of the SBS business, based on the types of products and services sold, and an analysis of how the Chief Operating Decision Makers review, manage and are compensated, the Company determined that it operates as one segment.
Principles of Consolidation	Principles of Consolidation These Consolidated Financial Statements include those of the Company and its wholly owned subsidiaries: Schmitt Measurement Systems, Inc. and Schmitt Industries (Canada) Limited. All significant intercompany accounts and transactions have been eliminated in the preparation of the Consolidated Financial Statements.
Reclassification	Reclassification Certain amounts in the prior period Consolidated Balance Sheet have been reclassified to conform to the presentation of the current period. Certain amounts in the prior periods presented have been reclassified to conform to the current period financial statement presentation. These reclassifications have no effect on previously reported net income (loss).
Revenue Recognition	Revenue Recognition The Company determines the amount of revenue it recognizes associated with the transfer of each product or service. For sale of products or delivery of monitoring services to all customers, each transaction is evaluated to determine whether there is approval and commitment from both the Company and the customer for the transaction; whether the rights of each party are specifically identified; whether the transaction has commercial substance; whether collectability from the customer is probable at the inception of the contract and whether the transaction amount is defined. If a transaction to sell products or provide monitoring services meets all of the above criteria, revenue is recognized for the sales of product at the time of shipment or for monitoring services at the completion of the month in which monitoring services are provided. The Company incurs commissions associated with the sales of products, which are accrued and expensed at the time the product is shipped. These amounts are recorded within general, administration and sales expense. The Company also incurs costs related to shipping and handling of its products, the costs of which are expensed as incurred as a component of cost of sales. Shipping and handling fees billed to customers, which are recognized at the time of shipment as a component of net revenues, were $21,066 and $24,242 for the nine months ended February 29, 2020 and February 28, 2019, respectively.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash The Company generally invests its excess cash in money market funds. The Company’s investment policy also allows for cash to be invested in investment grade highly liquid securities, and the Company considers securities that are highly liquid, readily convertible into cash and have original maturities of less than three months when purchased to be cash equivalents. The Company’s cash consists of demand deposits in large financial institutions and money market funds. At times, balances may exceed federally insured limits. Restricted cash consists of an amount held in escrow related to the sale of the balancer business segment, as described in Note 8. Once certain events are complete, the restrictions on this cash payment will be released. The following table provides a reconciliation of cash and cash equivalents and restricted cash as reported within the Consolidated Balance Sheets as of February 29, 2020 and May 31, 2019 t Statement of Cash Flows for the nine months ended February 29, 2020 February 29, 2020 May 31, 2019 Cash and cash equivalents $ 10,544,255 $ 1,467,435 Restricted cash 420,000 — Total cash, cash equivalents and restricted cash shown in the Consolidated Statement of Cash Flows $ 10,964,255 $ 1,467,435 The amounts in m m
Accounts Receivable	Accounts Receivable The Company maintains credit limits for all customers based upon several factors, including but not limited to financial condition and stability, payment history, published credit reports and use of credit references. Management performs various analyses to evaluate accounts receivable balances to ensure recorded amounts reflect estimated net realizable value. This review includes using accounts receivable agings, other operating trends and relevant business conditions, including general economic factors, as they relate to each of the Company’s domestic and international customers. In the event there is doubt about whether a customer account is collectible, a reserve is provided. If these analyses lead management to the conclusion that a customer account is uncollectible, the balance will be directly charged to bad debt expense. The allowance for doubtful accounts was $99,442 and $36,826 as of February 29, 2020 and May 31, 2019, respectively.
Inventories	Inventories Inventories are valued at the lower of cost or net realizable value with cost determined on the average cost basis. Costs included in inventories consist of materials, labor and manufacturing overhead, which are related to the purchase or production of inventories. Write-downs, when required, are made to reduce excess inventories to their net realizable values. Such estimates are based on assumptions regarding future demand and market conditions. If actual conditions become less favorable than the assumptions used, an additional inventory write-down may be required. As of February 29, 2020 February 29, 2020 May 31, 2019 Raw materials $ 116,814 $ 347,095 Work-in-process 536,513 376,375 Finished goods 403,757 517,662 $ 1,057,084 $ 1,241,132
Property and Equipment	Property and Equipment Property and equipment are stated at cost, less depreciation and amortization. Depreciation is computed using the straight-line method over estimated useful lives of three to seven years for furniture, fixtures, and equipment; and twenty-five years for buildings and improvements. Expenditures for maintenance and repairs are charged to expense as incurred. As of February 29, 2020 February 29, 2020 May 31, 2019 Land $ 299,000 $ 299,000 Buildings and improvements 1,840,025 1,814,524 Furniture, fixtures and equipment 396,986 498,476 2,536,011 2,612,000 Less accumulated depreciation (1,876,748 ) (1,858,593 ) $ 659,263 $ 753,407 Depreciation expense for the nine months ended February 29, 2020
Lease Accounting	Lease Accounting The Company determines if an arrangement is a lease or a service contract at inception. Where an arrangement is a lease the Company determines if it is an operating lease or a finance lease. Subsequently, if the arrangement is modified the Company reevaluates the classification. Buildings leased to others under operating leases are included in property, plant and equipment. See Note 6.
Intangible Assets	Intangible Assets Amortizable intangible assets, which include purchased technology and patents, are amortized over their estimated useful lives ranging from five to seventeen years. As of February 29, 2020 $2,085,362 and Amortization expense for both the nine months ended February 29, 2020 .
Customer Deposits and Prepayments	Customer Deposits and Prepayments Customer deposits and prepayments consists of amounts received from customers as prepayments for orders that have been received and have been produced but have not yet shipped, credit balances for items returned by customers for which refunds have not yet been provided and deposits made by customers in advance of production.
Use of Estimates	Use of Estimates The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
