Designed by Jesper Voxnaes, the Columbia River Knife & Tool Pilar Folding Knife is named after Ernest Hemingway's beloved boat, Pilar, that he used for renegade surveillance of German U-boats during WWII in Caribbean waters. The Pilar utilizes 8Cr13MoV blade steel; and the blade deploys with a thumb slot, and locks open with a frame lock. The flat-ground, modified wharncliffe blade is well suited for slicing and piercing. The stainless steel handle holds up to hard work; and 2 finger choils keep your finger off the blade. The sleek-designed knife carries comfortably with a reversible, steel pocket clip. The Columbia River Knife & ToolPilar is a reliable and sturdy EDC folding knife that's easily concealed and quickly deployed.
