Sharpness Measuring

With woodworking tools the only measure that matters is: Does it pare, chop, cut wood as needed and leave a surface that works as intended. Ok that's out of the way, now on the the reason for this post.

There are so many variables in sharpening, oil stones, water stones, natural, man made, diamonds, sandpaper, strop with compound and without, leather, MDF, maple and on and on. Like many folks I have tried many of 'em and the eternal question is which works the best. The answer is usually: "It depends." Because the answer many times depends on what steel, O-1, A-2, PM-v11, D2, K-510, and more, as with stones the number is almost endless.

BTW, I will cut to the chase.  The other day I ordered an Edge-On-UP sharpness tester. I've not a clue if it will tell me anything but I figure it was worth taking a flyer on. At a minimum I hope it will settle the strop question and if it does it will be worth toting the note. What I'm also hoping is it will help determine if there is a difference in oil, water, and/or natural vs. man made, and jig vs. freehand. I expect the answer will at the end of the day still be....It depends.

Big expectations, the UPS girl should deliver it sometime today. Did I ever post photos of my UPS girl? Damn I know better but sometimes I can't help myself.
