Exhibit 99.1

ACME UNITED CORPORATION REPORTS FIRST QUARTER SALES INCREASE OF 10%
AND 13% INCREASE IN EPS 

FAIRFIELD, CONN. – April 20, 2017 – Acme United Corporation (NYSE MKT:ACU) today announced that net sales for the quarter ended March 31, 2017 were $27.7 million, compared to $25.3 million in the first quarter of 2016, an increase of 10%.

Net income was $659,000 or $0 .18 per diluted share for the quarter ended March 31, 2017, compared to $565,000 or $0.16 per diluted share for the comparable period last year, an increase of 17% in net income and 13% in earnings per share.

On February 1, 2017, the Company acquired the assets of Spill Magic, Inc. for $7.2 million in cash. Spill Magic products are leaders in absorbents that encapsulate spills into dry powders that can be safely disposed, helping to avoid slips and falls on our customers’ premises. Spill Magic had sales of $6.3 million in 2016. The Company’s first quarter 2017 revenues included approximately $1.1 million from the sales of Spill Magic products.

Walter C. Johnsen , Chairman and CEO said, “Our team executed well and delivered solid growth in both sales and earnings. We began shipping our proprietary Westcott glue guns, expanded our distribution of Camillus hunting knives and Cuda fishing tools, and realized robust growth of first aid components and Smart Compliance kits. Our DMT sharpener business, which we acquired in February 2016, continued to expand. We are pleased to welcome the management of Spill Magic to our company and look forward to building our business together.”

 For the first quarter of 2017, net sales in the U.S. segment increased 9% compared to the same period in 2016. Net sales in Canada were constant in U.S. dollars and decreased 3% in local currency compared to the same period in 2016. European net sales increased 38% in both U.S. dollars and local currency compared to the first quarter of 2016 mainly due to new customers in the office products channel and sales of DMT products.

Gross margin  was 38% in the first quarter of 2017 versus 36% in the comparable period last year. The higher gross margin was primarily due to efficiency improvements in the Company’s first aid operations and a better product mix.

Mr. Johnsen  reiterated guidance for 2017 of approximately $137 million in revenues, $6.7 million in net income, and $1.76 earnings per share.

The Company’s bank debt less cash on March 31, 2017 was $38 million compared to $34 million on March 31, 2016. During the twelve month period ended March 31, 2017, the Company paid approximately $7.2 million for the acquisition of the assets of Spill Magic and distributed $1.3 million in dividends on its common stock. During the twelve month period, the Company generated $6.3 million in free cash flow.
