This tool has a flat grind on the front and a chisel grind on the top, but none of the edges are actually sharpened. It is designed for prying, wedging, and pounding rather than cutting.
I customized mine to better suit my needs. I ground the rounded back edge flat for a couple of inches at the top to use as a hammer. I wrapped the grip area with black 550 cord and ground in a forefinger groove. Since mine is normally carried in a pocket I made a simple kydex cover for the "blade" portion of the tool.
