ACME UNITED CORPORATION REPORTS FOURTH QUARTER NET SALES INCREASE OF 23% AND NET
INCOME INCREASE OF 38% AND RECORD FULL YEAR RESULTS

         FAIRFIELD, CONN. - February 29, 2008 - Acme United Corporation
(AMEX:ACU) today announced that net sales for the quarter ended December 31,
2007 were $14.9 million compared to $12.1 million in the same period in 2006, an
increase of 23% . Net sales for the year ended December 31, 2007 were $63.2
million compared to $56.9 million in the same period in 2006, an increase of 11%
(10% in local currency).

         Net income for the fourth quarter ended December 31, 2007 was $546,000,
or $.15 per diluted share, compared to $396,000, or $.11 per diluted share, for
the comparable period last year, an increase of 38%. Net income for the year
ended December 31, 2007 was $4,022,258, or $1.09 per diluted share, compared to
$3,885,662, or $1.05 per diluted share, in the comparable period last year, an
increase of 4%.

          Net sales for the year ended December 31, 2007, in the U.S. segment
increased 10% compared to 2006 as the result of sales of new products, including
the iPoint electric pencil sharpener and market share gains. Net sales in Canada
for the year ended December 31, 2007 increased by 11% in U.S. dollars and 5% in
local currency compared to 2006 primarily due to higher sales of the iPoint
electric pencil sharpeners. Net sales in Europe for the year ended December 31,
2007 increased by 21% in U.S. dollars and 11% in local currency compared to 2006
due to higher sales of manicure items and expanded distribution of office
products.

         Gross margins were 42% for 2007 compared to 43% in 2006. The gross
margin decline in 2007 was due to product mix and increased cost of goods sold
on purchases from China due to higher raw material and labor costs and
depreciation of the U.S. dollar. Costs also increased due to the reduction of an
export tax credit in China.

                                       (1)



         Walter C. Johnsen, Chairman and CEO said, "The results in the fourth
quarter and the year represent strong growth in our market shares, expansion of
our distribution channels, and improvement in Europe. I am especially pleased
with the recent placement of our new products, including the iPoint razor pencil
sharpener and Microban school and office products, which are expected to
generate robust sales in 2008."

         The effective income tax rate improved to 36% in 2007 compared to 39%
in 2006 primarily due to the decreased losses in 2007 in Europe where there is
no recorded tax benefit for losses. The European business is improving due to
operational improvements and sales growth.

         The Company's bank debt less cash on December 31, 2007 was $5.2 million
compared to $6.4 million on December 31, 2006, a decrease of $1.2 million. This
change primarily resulted from the Company's payments of $600,000 for
acquisitions and $500,000 for shareholder dividends, which was offset by the
Company's generation of $2.7 million in cash flow from operations.

         ACME UNITED CORPORATION is an innovative supplier of cutting devices,
