                      FOR IMMEDIATE RELEASE April 21, 2006


ACME UNITED CORPORATION REPORTS 16% SALES GROWTH

         FAIRFIELD, CONN. - April 21, 2006 - Acme United Corporation (AMEX:ACU)
today announced that net sales for the quarter ended March 31, 2006 were $12.3
million compared to $10.6 million in the comparable period of 2005, an increase
of 16%.

         Net income was $760,000 or $.20 per diluted share for the first quarter
ended March 31, 2006 compared to $650,000 or $.17 per diluted share for the
comparable period last year an increase of 17%. During the first quarter of
2006, the Company began expensing the fair value of stock options in accordance
with the new SFAS 123R accounting rule. This accounting change reduced first
quarter net income by $66,000.

         Net sales for the first quarter in the U.S. segment increased 19% as
the result of a sales initiative with a large warehouse club chain and the
initiation of a continuing program at a global superstore. Sales in Europe and
Canada increased by 5% in both U.S. dollars and local currency.

         Gross margins were 45.3% in the first quarter of 2006 versus 45.9% in
the first quarter of 2005. The lower margin in 2006 is due to expedited freight
costs and other one time expenses associated with the launch of a new program to
a global customer in Europe.

         Walter C. Johnsen, President and CEO said, "Acme United had solid sales
growth in the first quarter, and it is rewarding to see our products on the
shelves of new customers. We anticipate continued growth during the year as our
new programs are fully implemented."

         The Company's bank debt on March 31, 2006 was $7.8 million compared to
$2.0 million on March 31, 2005. The increase in bank debt was primarily used in
the funding of additional inventory amounting to $5.2 million and repurchases of
Acme stock of $2.6 million. We increased inventory earlier this year in order to
minimize air freight costs during our back to school season. We expect inventory
levels to normalize in the second half of 2006.
