In praise of peening...

I recently got a Leatherman PST in trade. It needed some TLC. I decided to pull it apart, attend to any mechanical issues, and buff it all nice and shiny again. The screwed pivots suffered some wear/damage, as I don't have the correct tools for disassembly so I bought a length of 3/16" Brass from the local hardware store and peened all the joints. I have to say that careful peening with accurately sized stock in decently sized holes leads to a wonderful feeling. There's zero play or wiggle throughout the entire tool, and it's possible to dial in just the perfect amount of friction for closing and opening. It's a feeling of precision and quality that is just slightly above even what one experiences from even a new Leatherman, from one with conventional fasteners that is. Of course, one can further tighten the peened joints at some point in the future (if ever needed). Drill out a joint, to replace a tool, just like with a SAK. There's a slight decrease in section with a peened Leatherman as the rivets stick out less than threaded fasteners, and this aids pocketability a bit as it slips in or out of a pocket freer than with the relatively snaggly stock fasteners. The PST also looks cool with the peened Brass heads :) All in all, I am very pleased with the operation.
