Tree topping? How sharp CAN it be?

[BluntCut MetalWorks]

According to Obsessed With Edges - Flitz paste is abrasive (aluminum oxide, at ~3 micron particle size). http://www.bladeforums.com/forums/showthread.php/952736-Metal-polish-paste-dulling-the-edge

This morning, I remeasured my 940 s30v angle is ~26* incl. After schred some more newspaper, under 400x, I found deformeds & microchips. I don't think, I can overcome this steel & ht limitations (for this particular knife) at angle below 30*.

I asked because you achieved hht - I must pick your brain and oh desperation on my part while trying to turn bm 940 s30v into a razor

update: resharpened to 30* incl (return to its original angle before my ill-conceived inspiration), shave, schred, shave smoothly with no fuss. *the end*.

Yes, Flitz is ~3 micron AlOx. I didn't figure that out on my own, but passed it along. One of our other members (thanks to 'alabamaomi' :thumbup contacted the manufacturers of Flitz and Simichrome for that info, and posted in this thread -->: Flitz and semichrom msds info

Cutting a free standing (thin) cigarette paper is a pretty good benchmark.

I sincerely don't believe that it is possible, a silk scarf yes it's doable I saw that, but a free standing rice paper...I doubt it. I want to see that posted on you-tube though, if any... LOL

See post #26 in this thread (video is linked there).

Excuse me, but are you saying that YOU actually 'saw' someone simply drop an ordinary silk scarf onto a stationary knife blade and the scarf cut itself in two?
Would you give us a few details? What sort of blade? Thai silk or Chinese silk (one is thicker and more coarse than the other.)

I don't know what sort of a silk that was, but the blade was a katana sword, and the documentary was on discovery channel long time ago.
