I used to work in a machine shop. Tool crib manager used to hand sharpen all our twist drill bits by eye. They were like new. I used to sharpen all my own bits with the fine grinding wheel on my grinder. Got pretty good at it. As far as the $100+ bit grinders, I've never used one. I think the guide designed here along with a grinder would save anyone a lot of money.
I wrapped black electrical tape around a frayed Apple cable and the adhesive dissolved the insulation coating on the cable. I couldn't believe it. I would advise against electrical tape!
