Anyone know of any decent "keychain" utility knife blades? I have a few that have either come with used lots, or came along with a smaller knife in a gift set, and have dulled. You just don't find the small ones in stores. I think, with some of the newer heavier plastics Shapeways is using, it will be great. Should make it less expensive, too. Metal options are not cheap there.
Great mod! Like the Havalon Evolve, but definitely better thought out and engineered, and obviously better made. And, if you've already got a Skeletool as I do--a lot less expensive.
