Basis Of Presentation [Abstract]
Basis Of Presentation	NOTE A – BASIS OF PRESENTATION The consolidated interim financial statements included herein are unaudited and have been prepared by the Company pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). In the opinion of management of the Company, the consolidated interim financial statements reflect all the adjustments which were of a normal recurring nature necessary for a fair presentation of the results of the interim periods. The condensed consolidated balance sheet as of December 31, 2018 is summarized from audited consolidated financial statements, but does not include all the disclosures contained therein and should be read in conjunction with the 2018 Annual Report on Form 10-K /A . Interim results for the period are not indicative of those for the year.  On January 3, 2017, the Company and its wholly-owned subsidiary, Presto Absorbent Products, Inc. (“PAPI”), entered into an asset purchase agreement wherein substantially all PAPI assets were sold and certain liabilities were assigned to Drylock Technologies, LTD. (“Drylock”) in exchange for $68,448,000 . The asset purchase agreement also provided for additional proceeds of $4,000,000 upon the sale of certain delayed assets, consisting of machinery and equipment that were the subject of an involuntary conversion. The sale of the delayed assets was consummated during the second quarter of 2018 and resulted in no gain or loss. As a result of aforementioned transactions, the Company classified its results of operations for all periods presented to reflect its Absorbent Products business as a discontinued operation and classified the assets and liabilities of its Absorbent Products business as held for sale. See Note K for further discussion.

Revenues

Revenues [Abstract]
Revenues	NOTE C – REVENUES The Company’s revenues are derived from short-term contracts and programs that are typically completed within 3 to 24 months and are recognized in accordance with ASC Topic 606, Revenue from Contracts with Customers . The Company’s contracts each contain one or more performance obligations: the physical delivery of distinct ordered product or products. The Company provides an assurance type product warranty on its products to the original owner. In addition, for the Housewares/Small Appliances segment, the Company estimates returns of seasonal products and returns of newly introduced products sold with a return privilege. Stand-alone selling prices are set forth in each contract and are used to allocate revenue to the corresponding performance obligations. For the Housewares/Small Appliances segment, contracts include variable consideration, as the prices are subject to customer allowances, which principally consist of allowances for cooperative advertising, defective product, and trade discounts. Customer allowances are generally allocated to the performance obligations based on budgeted rates agreed upon with customers, as well as historical experience, and yield the Company’s best estimate of the expected value for the variable consideration.  The Company's contracts in the Defense segment are primarily with the U.S. Department of Defense (DOD) and DOD prime contractors. As a consequence, this segment's business essentially depends on the product needs and governmental funding of the DOD. Substantially all of the work performed by the Defense segment directly or indirectly for the DOD is performed on a fixed-price basis. Under fixed-price contracts, the price paid to the contractor is awarded based on competition at the outset of the contract and therefore, with the exception of limited escalation provisions on specific materials, is generally not subject to any adjustments reflecting the actual costs incurred by the contractor.  For the Housewares/Small Appliance segment, revenue is generally recognized as the completed, ordered product is shipped to the customer from the Company’s warehouses. For the relatively few situations in which revenue should be recognized when product is received by the customer, the Company adjusts revenue accordingly. For the Defense segment, revenue is primarily recognized when the customer has legal title and formally documents that it has accepted the products. There are also certain termination clauses in Defense segment contracts that may give rise to the recognition of revenue, $9,412,000 of which was recognized during the third quarter of 2019. In some situations, the customer may obtain legal title and accept the products at the Company’s facilities, arranging for transportation at a later date, typically in one to four weeks. The Company does not consider the short-term storage of the customer owned products to be a material performance obligation, and no part of the transaction price is allocated to it.  The timing of revenue recognition, billings, and cash collections results in billed accounts receivable, and customer advances and deposits (contract liabilities) on the Company’s Condensed Consolidated Balance Sheets. For the Defense segment, the Company occasionally receives advances or deposits from certain customers before revenue is recognized, resulting in contract liabilities. These advances or deposits do not represent a significant financing component. As of September 29 , 2019 and December 31, 2018, $4,294,000 and $9,579,000 , respectively, of contract liabilities were included in Accounts Payable on the Company’s Condensed Consolidated Balance Sheets. The Company recognized revenue of $9,574,000 during the nine -month period ended September 29 , 2019 that was included in the Defense segment contract liability at the beginning of that period. The Company monitors its estimates of variable consideration, which includes customer allowances for cooperative advertising, defective product, and trade discounts, and returns of seasonal and newly introduced product, all of which pertain to the Housewares/Small Appliances segment, and periodically makes cumulative adjustments to the carrying amounts of these contract liabilities as appropriate. During the three and nine month periods ended September 29 , 2019 and September 30 , 2018, the Company reduced its estimate of returns of seasonal and newly introduced product by $265,000 and $421,000 , respectively. There were no other material adjustments to the aforementioned estimates during the same periods. There were no amounts of revenue recognized during the same periods related to performance obligations satisfied in a previous period. The portion of contract transaction prices allocated to unsatisfied performance obligations, also known as the contract backlog, in the Company’s Defense segment were $332,810,000 and $333,592,000 as of September 29 , 2019 and December 31, 2018, respectively. The Company anticipates that the unsatisfied performance obligations will be fulfilled in an 18 to 24 -month period. The performance obligations in the Housewares/Small Appliances segment have original expected durations of less than one year.  The Company’s principal sources of revenue are derived from three segme nts: Housewares/Small Appliance, Defense , and Safety , as shown in Note E. Management utilizes the performance measures by segment to evaluate the financial performance of and make operating decisions for the Company.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE D – EARNINGS PER SHARE Basic earnings per share is based on the weighted average number of common shares and participating securities outstanding during the period. Diluted earnings per share also includes the dilutive effect of additional potential common shares issuable. Unvested stock awards, which contain non-forfeitable rights to dividends whether paid or unpaid (“participating securities”), are included in the number of shares outstanding for both basic and diluted earnings per share calculations.

Business Segments [Abstract]
Business Segments	 NOTE E – BUSINESS SEGMENTS In the following summary, operating profit represents earnings before other income and income taxes. The Company's segments operate discretely from each other with no shared owned or leased manufacturing facilities. Costs associated with corporate activities (such as cash and marketable securities management) and the assets associated with such activities are included within the Housewares/Small Appliances segment for all periods presented.  On July 23, 2019, the Company purchased substantially all the assets of OneEvent Technologies, Inc., a Mount Horeb, Wisconsin company established in 2014. OneEvent’s cloud-based learning and analytics engine utilizes a series of sensing devices integrated with a cellular gateway to predict, alert, and prevent. Sensors measure a variety of environmental data including smoke, temperature, carbon monoxide, humidity, water, motion, and more. See Note L. Because a major focus of OneEvent is fire protection for buildings, homes, assets, and occupant, the Company has created a new operating segment, “Safety,” combining its operations with those of Rusoh, Inc., which designs and markets fire extinguishers. Previously, Rusoh, Inc. had been included in the Company’s Housewares/Small Appliance segment. Prior period segment information has been restated to reflect the Company’s current segmentation.

Fair Value Of Financial Instruments [Abstract]
Fair Value Of Financial Instruments	NOTE F - FAIR VALUE OF FINANCIAL INSTRUMENTS The Company utilizes the methods of fair value as described in Financial Accounting Standard Board (“FASB”) Accounting Standard Codification (“ASC”) 820, Fair Value Measurements and Disclosures, to value its financial assets and liabilities. ASC 820 utilizes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.  The carrying amounts for cash and cash equivalents, accounts receivable, notes receivable, accounts payable, and accrued liabilities approximate fair value due to the immediate or short-term maturity of these financial instruments.

Cash, Cash Equivalents And Marketable Securities [Abstract]
Cash, Cash Equivalents And Marketable Securities	NOTE G - CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES The Company considers all highly liquid marketable securities with an original maturity of three months or less to be cash equivalents. Cash equivalents include money market funds. The Company deposits its cash in high quality financial institutions. The balances, at times, may exceed federally insured limits. Money market funds are reported at fair value determined using quoted prices in active markets for identical securities (Level 1, as defined by FASB ASC 820).  The Company has classified all marketable securities as available-for-sale which requires the securities to be reported at estimated fair value, with unrealized gains and losses, net of tax, reported as a separate component of stockholders' equity. Highly liquid, tax-exempt variable rate demand notes with put options exercisable in three months or less are classified as marketable securities.  At September 29 , 2019 and December 31, 2018, cost for marketable securities was determined using the specific identification method. A summary of the amortized costs and fair values of the Company’s marketable securities at the end of the periods presented is shown in the following table. All of the Company’s marketable securities are classified as Level 2, as defined by FASB ASC 820, with fair values determined using significant other observable inputs, which include quoted prices in markets that are not active, quoted prices of similar securities, recently executed transactions, broker quotations, and other inputs that are observable.

There were no gross gains or losses related to sales of marketable securities during the sa me periods. Net unrealized (losses) gains included in other comprehensive income were ($28,000) and ($39,000) before taxes for the three month periods ended September 29 , 2019 and September 30 , 2018, respectively, and were $173,000 and $43,000 before taxes for the nine month periods then ended, respectively. No unrealized gains or losses were reclassified out of accumulated other comprehensive income during the same periods.  The contractual maturities of the marketable securities held at September 29 , 2019 are as follows: $29,913,000 within one year; $ 15,496,000 beyond one year to five years; $ 4,146,000 beyond five years to ten years, and $ 35,226,000 beyond ten years. All of the instruments in the beyond five year ranges are variable rate demand notes which can be tendered for cash at par plus interest within seven days. Despite the stated contractual maturity date, to the extent a tender is not honored, the notes become immediately due and payable.

Leases [Abstract]
Leases	NOTE I – LEASES The Company accounts for leases under ASC Topic 842, Leases , which was adopted on January 1, 2019. The Company’s leasing activities include roles as both lessee and lessor. As lessee, the Company’s primary leasing activities include buildings and structures to support its manufacturing operations at one location in its Defense segment, and warehouse space and equipment to support its distribution center operations in its Housewares/Small Appliances segment. As lessor, the Company’s primary leasing activity is comprised of manufacturing and office space located adjacent to its corporate offices. All of the Company’s leases are classified as operating leases.  The Company’s leases as lessee in its Defense segment provide for variable lease payments that are based on changes in the Consumer Price Index. As lessor, the Company’s primary lease also provides for variable lease payments that are based on changes in the Consumer Price Index, as well as on increases in costs of insurance, real estate taxes, and utilities related to the leased space. Generally, all of the Company’s lease contracts provide for options to extend and terminate them. The majority of lease terms of the Company’s lease contracts reflect extension options, while none reflect termination options.  The Company has determined that the rates implicit in its leases are not readily determinable and estimates its incremental borrowing rates utilizing quotes from financial institutions for real estate and equipment, as applicable, over periods of time similar to the terms of its leases. The Company has entered into various short-term leases as lessee and has elected a non-recognition accounting policy, as permitted by ASC Topic 842 .      3 Months Ending 9 Months Ending  Summary of Lease Cost (in thousands) September 29, 2019 September 29, 2019  Operating lease cost $ 178 $ 514  Short-term and variable lease cost 64 145  Total lease cost $ 242 $ 659   Operating cash used for operating leases was $242,000 and $659,000 for the three and nine months ended September 29, 2019, respectively. The weighted-average remaining lease term was 7.72 years, and the weighted-average discount rate was 5.5% as of September 29 , 2019.  Maturities of operating lease liabilities are as follows:     Years ending December 31: (In thousands)  2019 (remaining three months) $ 175  2020 693  2021 648  2022 648  2023 531  Thereafter 1,824  Total lease payments $ 4,519  Less: future interest expense 869  Lease liabilities $ 3,650  Lease income from operating lease payments for the quarter ended September 29 , 2019 was $444,000 . Undiscounted cash flows provided by lease payments are expected as follows:     Years ending December 31: (In thousands)  2019 (remaining three months) $ 444  2020 1,761  2021 1,755  2022 1,755  2023 1,755  Thereafter 15,795  Total lease payments $ 23,265  The Company considers risk associated with the residual value of its leased real property to be low, given the nature of the long-term lease agreement, the Company’s ability to control the maintenance of the property, and the creditworthiness of the lessee. The residual value risk is further mitigated by the long-lived nature of the property, and the propensity of such assets to hold their value or, in some cases, appreciate in value.

Discontinued Operations [Abstract]
Discontinued Operations	NOTE K – DISCONTINUED OPERATIONS On January 3, 2017, the Company and its wholly-owned subsidiary, Presto Absorbent Products, Inc. (“PAPI”), entered into an asset purchase agreement wherein substantially all PAPI assets were sold and certain liabilities were assigned to Drylock Technologies, LTD. (“Drylock”) in exchange for $68,448,000 . The asset purchase agreement also provided for additional proceeds of $4,000,000 upon the sale of certain delayed assets, consisting of machinery and equipment that were the subject of an involuntary conversion. The sale of the delayed assets was consummated during the second quarter of 2018 and resulted in no gain or loss. As a result of the aforementioned transactions, the Company classified its results of operations for all periods presented to reflect its Absorbent Products business as a discontinued operation and classified the assets and liabilities of its Absorbent Products business as held for sale. The Company’s pre-tax gain on sale of $11,413,000 , net of one-time transaction costs, was recorded in 2017 within earnings from discontinued operations.  The following table summarizes the results of the Absorbent Products business within discontinued operations for each of the periods presented:      Three Months Ended Nine Months Ended  (in thousands) (unaudited) Sept. 29, 2019 Sept. 30, 2018 Sept. 29, 2019 Sept. 30, 2018  Cost of sales $ - $ 68 $ 4 $ 57  Other income 2,122 2,122  Earnings from discontinued operations before provision for income taxes 2,122 68 2,126 57  Provision for (benefit from) income taxes from discontinued operations 445 (63) 446 (65)  Earnings from discontinued operations, net of tax $ 1,677 $ 131 $ 1,680 $ 122  During the third quarter of 2019, the Company recognized Other income from the settlement of a lawsuit for breach of contract.

Cash used in operating activities from discontinued operations was $1,050,000 and $562,000 for the nine m onths ended September 29, 2019 and September 30 , 2018, respectively. Cash provided by investing activities related to discontinued operations was $3,107,000 and $6,134,000 for the nine months ended September 29, 2019 and September 30 , 2018, respectively.  In connection with the asset purchase agreement discussed above, the Company entered into a 10 -year lease agreement with Drylock for a portion of its manufacturing and warehouse facilities. The lease agreement provided for total annual payments of $1,288,000 initially. During the fourth quarter of 2018, the lease agreement was amended to incorporate additional facilities that the Company built for Drylock. The amended lease provides for an initial term of approximately 14 years, and allows for successive three -year renewal periods, as well as options to terminate the lease early after five and ten years. The amended lease also provides for adjustments to the rental payments based on certain price indices, taxes, and space occupied. The Company estimates that annual payments under the amended lease will total $1,755,000 . The amounts received from Drylock for rental income are recorded in Other Income on the Consolidated Statements of Comprehensive Income.

Business Acquisition [Abstract]
Business Acquisition	NOTE L – BUSINESS ACQUISITION On July 23, 2019 , the Company’s wholly-owned subsidiary, OETA, Inc., purchased substantially all the assets of OneEvent Technologies, Inc., a Mount Horeb, Wisconsin company established in 2014 for $6,855,000 , including cash of $4,021,000 , forgiveness of a note receivable of $2,364,000 and a potential earn out, which is based on earnings over a seven year period. The current estimated value of the earn out is $470,000 , however, the value of the earn out will vary depending on actual earnings over the seven year period . OneEvent’s cloud-based learning and analytics engine utilizes a series of sensing devices integrated with a cellular gateway to predict, alert, and prevent. Sensors measure a variety of environmental data including smoke, temperature, carbon monoxide, humidity, water, motion and more. Pursuant to the terms of the transaction, the seller has subsequently changed its corporate name, and OETA, Inc. has now legally adopted the corporate name, OneEvent Technologies, Inc.  The acquisition was accounted for under the acquisition method of accounting with the Company treated as the acquiring entity. Accordingly, the consideration paid by the Company to complete the acquisition has been recorded to the assets acquired and liabilities assumed based upon their estimated fair values as of the date of acquisition. The carrying values for current assets and liabilities were deemed to approximate their fair values due to the short-term nature of these assets and liabilities. The following table shows the amounts recorded as of their acquisition date. These estimates are based on a preliminary valuation, which the Company expects to finalize during the first quarter of 2020.

The amount of goodwill recorded reflects expected synergies with the Company’s other subsidiary in the Safety segment, Rusoh, Inc. The recorded goodwill is deductible for income tax purposes over a fifteen year period. The Company’s results of operations for 2019 include revenue of $13,000 and loss of ($298,000) from the acquired facility from the date of acquisition through September 30, 2019. The following pro forma condensed consolidated results of operations has been prepared as if the acquisition had occurred as of January 1, 2018.

Recently Issued Accounting Pronouncements [Abstract]
Recently Issued Accounting Pronouncements	NOTE M – RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , which eliminates the performance of Step 2 from the goodwill impairment test. In performing its annual or interim impairment testing, an entity will instead compare the fair value of the reporting unit with its carrying amount and recognize any impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss. The standard is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements.  In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . ASU 2016-13 provides guidance for estimating credit losses on certain types of financial instruments, including trade receivables, by introducing an approach based on expected losses. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. ASU 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The guidance requires a modified retrospective transition method and early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-13 on its consolidated financial statements.
