I have a bicycle that's locked with a 2 cm/0.8" hardened steel lock that I have unfortunately lost the key to. I would very much like to get the bike operational again, but all I have is a 900W reciprocating saw. I had some moderate success with it and a metal blade, until the blade became dull after getting about 1 mm through the lock. Note that this was a very cheap blade, and I'm sure I can get some that are harder and more durable, but is it actually worth the effort and cost of blades to use a reciprocating saw for this? Or is an angle grinder a better tool that I should acquire instead?
