CRKT Edgie Self Sharpening Knife

The Edgie™ hones its edge every time it is opened or closed. This first CRKT Edgie model was designed to be a simple, affordable utility knife with broad appeal. The secret is a 400-grit diamond-coated spring sharpener built into the folder frame. (Why didn’t I think of that?) It is placed at the precise angle to give the Edgie’s Wharncliffe blade a sharpening stroke as it is closed, and again as it is opened. Not only do you never need to sharpen the Edgie with stones or wheels, but you should not, because it may alter the Edgie’s proper self-sharpening edge angle. Of course, it is important during a long cutting work session to periodically open and close the blade to maintain the edge. The high-carbon stainless steel blade in satin finish features a strong full-width spine for most of its length, dual hollow grinds, and the single cutting edge. Because the internal diamond sharpening strip works on this one edge only, a tiny burr forms, which actually helps cutting action, acting as a microserration. This makes the Edgie tops for cutting cardboard boxes, rope, cord and even ripe tomatoes.
