Burglars and safecrackers sand the ridges off.

This sounds like it'd work, but quite tedious.

Two words - "power tools" !!! ;-) I've sanded my finger tips down rather well with a belt sander and a fine grit belt on numerous occasions. While I've speculated that I probably wouldn't leave much of a finger print, I've never actually tried to take prints after such an operation.
