new fixed blade

Thomas Linton said:
However, it is worth noting that, after examining, by now, several dozen knives used by professional wood-workers, very few (2) had a Scandi grind. That is because free-hand sharpening tends, over time, to convex the edge -- the sum of many "errors" in angle. They don't have time for jigs.

Thomas,
I have heard several people comment on this "convexing" by always free hand sharpening. Besides crock sticks for my kitchen knives, I have never done anything but freehand sharpened my knives, how do you know if your edge is convexed? I realize it doesn't really matter but I am interested if my knives have convex edges by accident. Chris

Chris, after hearing that story for decades from folks, including Draper and Loveless, I finally took a straightedge and good magnifying glass to my knives and my wife's grandfather's knives. Sure enough, the last bit of each blade's edge was curved. I have examined every old knive I can get my hands on. Mostly, the pattern shows up.

I think if you used a circular motion on each side you would reduce this effect vs. the "one stroke on each side" method that I was taught.

(I use crock sticks of several coarsenesses for removing metal "sharpening," and down to cardboard for refinement.)

I have a 6x glass around here somewhere, I will have to dig it out and take a peek. I use the one stroke on each side method, more precise than circles IMO. I bought a compact set of lansky crocks at Gander mountain last week. It has both medium and fine sticks and storage holes in the base, really neat compact rig. Chris
