The original historical Roach Belly knife was a short blade with a pronounced upswept curve and a sharp point. It was most likely named after the common Roach Fish, which had a similarly round curving belly. It was popular in 17th century Britain and quite common in the American Colonies because it was inexpensive and versatile. Cold Steel's interpretation keeps the Roach Belly's economy, versatility and effectiveness and the shape; but uses the latest high-tech materials. The hollow ground blade is made of German 4116 Stainless steel, and given a fine sharp edge that's easy to maintain. Instead of the traditional wood handle, it's made of tough Polypropylene, so it's impervious to the elements and won't swell, shrink, rot or crack.
