So I was at work today (I do construction) and I am cutting sheathing off of these cables with a hooked razor and my hand slips. Luckily my other hand was the to stop the blade, but un-luckily my skin is penetrable.  I got a 2 1/2  inch cut about 3/4s an inch deep, 11 stitches , some perkasets (probably spelled wrong), and a whole lot of pain...Thank god for workers comp.
