I don't know if this is common knowledge or not, but on the chance it isn't I thought I'd share. I recently traded for a LM Micra to replace my Vic Classic on my keychain, because the Micra has all the tools I need from a SAK or multi-tool, so now I don't have to carry my Farmer / Soldier in addition to a Spyderco. The neat thing about using the blade on the Micra is that you can leave the handle open so it's possible to get a four finger grip on a keychain sized knife. Not the best grip in the world with how thin the handle is, but it beats the 2 finger pinch grip of the Classic. The downward curve of the blade end even makes things more ergonomic.
