Idea? Making a lock tougher to pick.

[devildog]

I was reading in LSS the other day about locks that contain serrated key pins (all of them), serrated chambers (all of them), and serrated drivers (all of them with a couple serrated spools thrown in), and the author mentioned them as being the hardest to pick among standard pin tumblers (no sidebars, rotating pins, etc). He didn't mention a specific lock that has them, but apparently they exitst. He also said that serrated pins/chambers/drivers was the only type of security pin setup that MAY effectively neutralize a pick gun or electric vibration gun (and therefore, I imagine, a bump key) along with making manual picking extremely difficult.

An electric pick gun I can imagine, as it's not a once stroke type of thing. A manual pickgun, possibly. A bump key, with enough practice, I imagine would still work on a lock like that.
