Review on Efficient Shingle Splitting Blade 🔪 Knife Handle: Enhanced Performance for Roofing Tasks by Sherman Lancaster

It's a bit shocking how complete rubbish this is. Not only was it nowhere near sharp (there was no hint of a blade), when I spent 45 minutes on the grinder sharpening the edge, the BRAND NEW blade had 1/8" deep gouges. . What? as soon as I got it manage to sharpen it and try it, it becomes clear this steel was never heat treated. It creased like paper after a hard hit with a hammer. Pathetic and insulting. Too bad Amazon sells this crap.
