Santa gave me a couple of v bearings and I wanted to make a small wire stripper. I saw one that looks like a folding razor knife that has a v bearing in it. The D2 style roller cutters say they can cut 8000 ft of wire before they get dull. How many double sided razor blades would it take to cut 8000 ft of single strand solid 10-12 awg.(just the tip makes contact with the wire) It seems like the steel cutter would be better suited for thicker wire and not worth the extra cost for thinner wire? Am I missing something. I plan on making a couple of wire specific strippers rather than one that can sort of do everything. Does anybody have exper. with this type of stripper?
