I would like advice on cutting through a cable lock like this one:

Here's the deal- Near my place there is a cool vintage mountainbike from the mid 80s locked to a tree that I would notice every time I road past it, about once or twice a week. I thought it belonged to someone who worked in the area and they were just locking it to the same spot all the time. The other day I road past and the wheels were gone, a few days later it's still there, wheels missing. So it seems clear that it hasn't been locked up there anew every day, it's just been locked there for about 6 weeks now.

This is a cool bike and I don't want it to get trashed. It's starting to rain and it's gonna get ruined. I want to take this bike home to save it and run some ads on craigslist for a few weeks to see if the original owner can claim it. I'm sure plenty of people will pop on to let me know what a horrible person I am for trying to justify stealing a bike... 'how to free an abandoned bike' threads pop up every so often and that's how they usually go... but honestly I'm just interested in saving the bike from ruin because it's pretty unique, and honestly I'd be most pleased if the owner was able to claim it. I'm not trying to get a free bike.

So, any tips on how to get through a cable lock?
