Make some infill planes! Without power tools. That'll give you a good chance to wear out some files (and body floats, and all kinds of stuff).
I've thought about the breakage part, too. For better or worse, there's a Harbor Freight at the bottom of my hill (where the area switches from residential to commercial). Fortunately, out of sound and sight thanks to the hills in Pittsburgh, we don't hear any traffic or commercial anything. However, handy for anything broken, so I can replace a broken screwdriver with a 20 minute walk (to and from). I haven't broken one, though - not even the one that I cut for split nuts (and that one flexes some when working them).
The cheapies could be tempered to saw temper, too...or just ground until they're blue.
