ACME UNITED CORPORATION REPORTS RECORD SALES AND 16% EARNINGS INCREASE FOR FIRST
QUARTER

         FAIRFIELD, CONN. - April 18, 2008 - Acme United Corporation (AMEX:ACU)
today announced that net sales for the quarter ended March 31, 2008 were $14.3
million, compared to $12.2 million in the comparable period of 2007, an increase
of 17% (13% in local currency).

         Net income was $753,000 or $.21 per diluted share for the first quarter
ended March 31, 2008 compared to $650,000 or $.17 per diluted share for the
comparable period last year, a 16% increase in net income and 24% increase in
diluted earnings per share.

         Net sales for the first quarter 2008 in the U.S. segment increased 17%
compared to the same period in 2007 due to market share gains in the cutting and
first aid product categories. Net sales in Canada in the first quarter of 2008
increased by 8% in U.S. dollars but declined 7% in local currency due to soft
demand in the overall office products market. European sales in the first
quarter of 2008 increased 18% in U.S. dollars and 4% in local currency compared
to the first quarter in 2007.

         Gross margins were 42.0% in the first quarter of 2008 versus 43.6% in
the first quarter of 2007. The margin in 2008 declined mainly due to a
successful promotion of medication sales which carried a profitable, but lower
margin than our other product lines. Gross margins without the promotion would
have been 43.0% during the first quarter of 2008.

         Walter C. Johnsen, President and CEO said, "While the retail
environment is difficult, we are seeing success with our innovative and new
products. We are excited about the prospects of our new school tools, pencil
sharpeners, and antimicrobial scissors which begin shipping in the second
quarter. Our patented cartridge-based utility knife has had good reception by
its initial customers, and we are working to expand placement during the year."
