Thread: Convex edge

From my thread about using hanging pasted strops...

So, I did a very quick test last night on a warped Wapi. I put three sheets of paper (wetted out) under my diamond lapping film, and honed it up: 9um, 6um, 3um, 1um, 0.5um, 0.1um.

There was definitely some convexing going on. Using the polarizer filter on the scope (it doesn't come out in the image capture, however..) it was apparent that the bevel had some curvature to it.

The result?

Well, the bevel sure is smooth & shiny!

And subjectively, the actual edge seems to have less microchipping and edge distortion than the 0.1um edge I put on another razor using the film flat on the precision plate without the paper backing.

Not a real good comparisson, because different razor steel may react differently, etc...

Anyhow, I may reduce it to just one sheet behind the lapping film, and see how that goes...
