How about wire stripping? I tried the wood block with a screw in it that I saw in "Extension Cord Blues" thread, with no luck. I'm looking into the other thing from that thread with some interest, but have concerns about the fact that works on the same principle, and I am worried about how often I will have to change blades. The other one I looked at also works on the same principle, from TNTTooling.com, (the WSA tool, at the bottom of the page) but once again, same worries. Any suggestions, thanks.
