Many of my razors have been honed with one layer of electrical tape on the spine. Theorectically, it would make sense to keep them taped when polishing on a pasted paddle with either fine diamond paste or chromium oxide to maintain the same edge angle.

When I try this, the tape "drags" on the paddle and scrapes up some of the polishing compound.

When I polish the blades untaped, I seem to get just as good a result. I figure that the the pasted leather paddle has enough "give" to conform to the edge angle.

What do you guys do?
