The success of our Trench Knife inspired us to present an everyday function for this piece. In a scaled down version to two thirds of the original size, it now also adorns your desk as a letter opener. The blade is 4034 stainless steel, and the scales are made of handsome walnut. Made in the Boker knife manufactory in Solingen, Germany. Blade length: 3â€. Overall length: 6Â¾â€. Weight: 1.5 oz.
