[TheForge] Bike lock steel?

[Demon Buddha]

Damn I cannot recall the alloy.  Fairly common, though, as I recall.

Some guys in the ME dept. at UC Davis did testing on the Kryptonite
locks because of the claim that they were "unbreakable".  The easiest
way to break them without heat turned out to be a soaking in liquid
nitrogen, emplacement upon an anvil (of all things) and whacking the
piss out of it with a sledge hammer.  Large bolt cutters didn't fare
so well as the jaws got seriously notched up.
