Net sales in 2004 were $43.4 million versus $35.0 million in 2003, an increase of 24% (22% at constant currency). Net sales in the U.S. increased by 23% due to the success of new products, market share gains and the acquisition of Clauss Cutlery in June of 2004. Clauss added approximately $1.7 million to the U.S. sales growth in 2004. Combined sales in Europe and Canada increased by 14% (5% in constant currency). The Company's new business unit in Hong Kong began selling to global customers in January of 2004 and generated sales of $1.2 million in 2004. For the fourth quarter of 2004, net income was $754,000 or $.19 per diluted share compared to $227,000, or $.06 per diluted share in 2003. Net sales for the fourth quarter of 2004 were $10.9 million compared to $8.1 in the same quarter of 2003, an increase of 35% (33% at constant currency). Walter C. Johnsen, President and CEO, said, "We are particularly pleased with our new product successes and market share gains. Products introduced during the past 36 months accounted for 25% of 2004 domestic revenues. I am particularly happy with the momentum we have going into 2005." Gross margins were 45% in 2004 versus 38% in 2003. The improvement is primarily due to increased sales of new products and productivity gains.
