If you are trying to reproduce the Zowada, Nano bevel, try some clear packing tape over electrical tape. It is very thin and abrasion resistant.

The packing tape sold at USPS is supposed to be very thin and exceptionally strong, it does not say who the manufacture is, other than, it is imported. 3-4 bucks for a decent roll.

It was recommended on a Knife site, I don’t recall which one, for taping up knives use in sharpening jigs to keep from scratching and use on the jig, in place of blue masking tape.

It is inexpensive and applies and comes off easily. I have been able to get very nice, Nano bevels and straight edges with it.
