Made this Pinch “knife” Blade out of some aluminum plate. And Yep, it is sharpened. It makes for a great tool to train pinch between the heel of your palm and the finger tips/thumb. Plus there’s the added fun of making sure you don’t let it slide out of your grip weird and slice up your hand (I prefer to lift it with the edge facing away from my skin). Worked up to a single @ 80lbs.
