The CRKT Shakaulu is the fusion of two ancient tools: the ulu palm knife and scraper of Alaskan and Canadian tribes, plus a cleaver. Both tools go back many thousands of years. The blade of the Shakaulu is exceptionally thick and heavy, the hallmark of a traditional cleaver. It has a high convex grind for maximum strength. The blade is made of 65MN carbon steel for maximum toughness, and is black powder coated to resist corrosion.
