Does anyone around here have the tools to break a Kryptonite U-Lock? Not a bic pen; I'm talking actually destroying the lock and not the bike that's in it.

Unrelated: My email works again! Hooray!

eh, drape a piece of canvas over the bike where sparks might hit. ^_^

I didn't do this when I cut through the kryptonite on my bike with an angle grinder, and didn't have any blemishes on my bike as a result. I was not pointing most of the sparks at the frame (even in cramped quarters you'll have a little room to adjust).

But they have very little mass (smaller than sand) so the don't hold enough heat to really do anything to the paint (which they're only touching for the shortest of time as they bounce off), and while they are sharp they don't have very much momentum. I think that acetylene cutting makes much larger hotter sparks than grinding.
