The CRKT Edgie is a knife that will sharpen itself during normal use. This is the brainchild of inventor Maj. Howard Pope (USAR Ret.), who collaborated with custom knifemaker and Knifemakers' Guild member Steve Jernigan. The Edgie 2 is a dual-edged lockback with a 3.25" blade. The frame is superstrong thanks to the stainless steel InterFrame build with Zytel scales.
