Thanks, all. I appreciate your kind words. Regarding the vinegar/lemon juice etching...I do it two ways. The first is to simply let the blade sit in the solution, then clean it with water and buff it with steel. I repeat the process three or four times, or until I like the finish.
The second method I us is to add a little current. I use a couple of alligator clips, a 6V lantern battery, and a piece of scrap steel. I hook the positive terminal to the tang of the blade and the negative terminal to the piece of scrap steel which I half-submerge into the solution. Then I put the knife into the mixture and let it "cook." It greatly speeds up the process and the results are more aggressive. I let it soak anywhere from half and hour to a couple of hours, clean and buff it, then repeat the process.
