I have a Leatherman Wave multitool that's getting a bit loose and some rust and spotting is starting on the in-erds, I'd like to get inside there with some fine steel wool and oil it up. Is there a 5 prong torx wrench available anywhere to tighten the pivots on the leatherman wave? It didn't come with a wrench, and when I tried contacting Leatherman I was told all I could do is send it in for warranty. Any help is appreciated.
