I did the same as xyzzy, had a wart on the side of my thumb, cut it off really deep with a razor blade. Thought i was gonna bleed to death for a while (jk) after it had saturated the third plaster in fifteen minutes, but it stopped after a while and healed over without leaving any scar. It's never come back, and despite the bloodloss i'd do exactly the same again if i ever got another wart. Well, except perhaps if it were on my face. I think i'd get a professional to tackle that one.
