Razor blade development of dry gum

I once overprinted and overpigmented a gum print. (Did I say once?) I saw it
laying about one day and decided to see what would happen if I scraped it
with a razor blade. I used a single edged blade and dragged it firmly across
the print with the sharp edge pointing away from the direction of the drag.
It very nicely takes the top surface from the gum, more from the soft areas,
less from the hard. The print developed up rather nicely, and I still have
it. The blade edges did leave some trails which I believe could be
eliminated by rounding the edges off on a whetstone.

I never followed up on this but I thought I'd mention it. Perhaps someone
has already perfected such a system.
