ACME UNITED CORPORATION REPORTS 14% SALES GROWTH

FAIRFIELD, CONN. - July 21, 2006 - Acme United Corporation (AMEX:ACU) today
announced that net sales for the quarter ended June 30, 2006 were $17.0 million,
compared to $14.9 million in the comparable period of 2005, an increase of 14%.
Net sales for the six months ended June 30, 2006 were $29.2 million, compared to
$25.5 million in the same period in 2005, an increase of 15% (14% at constant
currency).

         Net income was $1,506,000 or $.40 per diluted share for the second
quarter ended June 30, 2006 compared, to $1,314,000 or $.34 per diluted share
for the comparable period last year, an increase of 15% in net income and 18% in
diluted earnings per share. Net income for the six months ended June 30, 2006
was $2,265,000, or $.61 per diluted share compared to $1,964,000, or $.52 per
diluted share in the comparable period last year, a 15% increase in net income
and 18% in diluted earnings per share.

         Net sales for the six months ended June 30, 2006 in the U.S. segment
increased 15% as the result of sales initiatives with several major retailers
and superstores. Sales in Europe and Canada increased by 12% in U.S. dollars and
8% in local currency. This sales growth was principally driven by new sales to a
large pan-European superstore and an expanded product line with a major European
retailer.

         Gross margins were 43.7% in the second quarter of 2006 versus 45.2% in
the comparable period last year. For the first six months of 2006 gross margins
were 44.4% compared to 45.5% in the same period in 2005. The lower margins in
2006 were primarily the result of one time expenses associated with filling
large orders on an expedited basis for the new business in Europe. These
expenses lay the foundation for future revenues to large multinational customers
in Europe.

                                      (1)


         Walter C. Johnsen, President and CEO said, "Acme United had an
excellent quarter. We reported the highest quarterly sales and earnings in the
Company's history. We expanded our distribution channels, developed new products
and continued to gain market share. Acme has been selected for a second
consecutive year by Fortune Small Business as one of the top 100 fastest growing
public companies in the U.S."

         The Company's bank debt on June 30, 2006 was $10.2 million compared to
$5.0 million on June 30, 2005. The increase in bank debt during the twelve month
period was used to buy additional inventory of $3.8 million, repurchase $1.4
million of Acme stock, demolish a former manufacturing site for $1.5 million and
make dividend payments to shareholders of $.4 million. Based on anticipated cash
flow, the debt level is expected to decline during the second half of the year.


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