Ok, maybe not because they break, but because you can fix them? I mean this group loves stropping razors, and even if we aren't the handiest with a hone, most if not all wish we were. Currently I'm on an Ipod Mini kick. I've found that they are reasonably available in less than functioning form, but are quite within my skills to repair.
So my question to my friends here, what do you like, even as a side, once and a while hobby, to rip apart and make better?
