I use blue painters' tape, which works fine.
Well, I don´t do any high end knifes so this blue painters´ tape is enough to me and it won´t leave any glue residue.

I made my own 8" wheels of MDF which is some 1" thick and I run them with green compound. I´ll get deburr and polish with the same run.
That green compound should be #100 000 grit / 0,2-0,5 micron what late Dr Vadim told on his videos.

Scissors Sharpening / Re: Scissors for Kevlar
April 02, 2020, 11:07:58 PM
Hello everybody. This is my fist post to this forum and btw I am a Finn.  ;)  I am newbie in this levels sharpening and I haven´t tried yet to sharpen a pair of shears with my old updated
SA-250 Tormek. I have done beaty salons and industrial shears/scissors with different methods and machines few times.
I have been on 90s a mechanic on my friends small raceboat team (tohatsu 40 and Yamaha 70) and we made our own race catamarans of fiber glass, carbon fiber, kevlar and aramid fiber. Those special fibers was an annoying stuff to cut and my friend sharpened his Fiskars scissors with anglegrinder so you could cut + one meter or so. That rough sharpening method of his stuck in my memory for several decade and now I know why it worked. I stumbeled in few videos and there they talked of "serrated or corrugated" thumb blades. They sharpened blades first and then they
"serrated or corrugated" thumb blades with special machine or then you could do it with diamond file or chequering file. Even it isn´t Tormek machine or method but somebody may have help of it
I will put few links here. Plese, don't shoot the messenger.  ;) :D
