Wow, that's fast. And I had no idea that sharpening a blade could be that fast! When I saw he was gonna just use the rag wheel buffer, I thought it was gonna be lame, but the knife went from useless to razor sharp! I have two questions: 1) what is he talking about when he says "wire edge"? 2) what does he keep doing by running the blade on the wood every ten seconds or so? https://www.youtube.com/paulwheaton12#p/u/0/SOFcnP79bBU Please forward to folks that might be interested in this sort of thing. Many thanks!
