Hmmm.
Seems like SOG is doing rather well on this thread, and with good reason.
I've tried several other models and eventually decide on SOG.
Here's some comparisons:
Craftsman. POS. That's all.
Gerber. Too hard to open. A little rickety.
Swiss Tool. Locked up bank-vault tight. Unless you have big, strong fingernails, forget it. Besides, Victorinox polishes the HECK out of everything. What you need in a multi-tool is nice, sharp, crisp edges on your tools.
Leatherman WAVE. I'd bet that, like me, most people on this forum carry a nice knife in addition to their multi-tool. It makes no sense to carry a multi-tool that was designed around one-hand opening and lockin blades. If you wanted to carry a Multi-tool INSTEAD of another knife, then sure, the WAVE would be perfect, but other than that I'd skip the knife-intensive design of the WAVE and get...
SOG: I have a Paratool which is one of the lower-end multi-tools SOG offers and I'd STILL choose it above the others I've tried listed above. GREAT workmanship, quality tools. Good sheath. WAYYYY under rated and under marketed. Leatherman and Gerber has nothing on SOG. I like my Paratool, but I'll probably buy two more other SOG multi-tools just because I think they're worth having and that I'd probably use them.
