And make almost no noise. That key-safe would be toast. I saw one used yesterday on a 2" high-pressure steam main (the steam was off, of course). 18 seconds per cut. I expect the key-safe is made from a harder material than the steam pipe, so I figured all of 45 seconds.

In one of the more upscale neighborhoods (Lower Merion) nearby, a group of thieves dressed up in bright red jumpsuits, drove a 24-foot panel truck up a driveway, put a sign out on the lawn: Sam's House Cleaning and Yard Services" and did exactly that. Cleaned out the house in broad daylight.
