ACME UNITED CORPORATION REPORTS FIRST QUARTER RESULTS

         FAIRFIELD, CONN. - April 20, 2007 - Acme United Corporation (AMEX:ACU)
today announced that net sales for the quarter ended March 31, 2007 were $12.2
million, compared to $12.3 million in the comparable period of 2006.

         Net income was $650,000 or $.17 per diluted share for the first quarter
ended March 31, 2007 compared to $759,000 or $.20 per diluted share for the
comparable period last year, a decrease of 15%.

         Net sales for the first quarter in the U.S. segment decreased 4%
compared to the same period in 2006. Sales in the first quarter of 2006 included
over $1 million of initial new product shipments to three major retail chains.
Since the products are now regular items for these retailers, the first quarter
of 2007's sales represented only restocking shipments. During the first quarter
of 2007, sales in Europe and Canada increased by 11% in constant currency, as
compared to the comparable period in 2006.

         Gross margins were 44% in the first quarter of 2007 versus 45% in the
first quarter of 2006. The margin in 2007 declined due to a higher proportion of
European sales at lower margins compared to margins in the U.S. segment.

         Walter C. Johnsen, President and CEO said, "While revenues in the first
quarter were approximately even with the same period last year, we look forward
to stronger sales in the coming quarters. Our award winning iPoint pencil
sharpeners will be shipped to many of our major customers for back to school
sales. We expect to begin new scissor and paper trimmer business in the second
and third quarters and start a rollout of new sewing items in the fourth
quarter. We believe these growth initiatives will provide the foundation for a
strong year in 2007 and forward momentum in 2008."

         The Company's bank debt less cash on March 31, 2007 was $7.1 million
compared to $6.8 million on March 31, 2006. The increase in bank debt was
primarily due to the purchase of additional inventory amounting to $1.8 million,
a $1.1 million payment for the demolition of a former manufacturing site and
repurchase of Acme stock of $0.4 million offset by earnings.

         On March 28, 2007 the Company announced a 4 cents per share quarterly
dividend on its outstanding common stock for shareholders of record on April 6,
2007, and is payable on April 27, 2007. This represents an increase of 33
percent or 1 cent per share over each of the previous seven quarterly dividends.


         ACME UNITED CORPORATION is a leading worldwide supplier of innovative
cutting, measuring and safety products to the school, home, office and
industrial markets.
