I agree with Kaius about Leathermans, they are great tools. My preference is Gerber, though. I always keep this in my car but apparently this version is only available to military.
I really like the Gerber, prices are great too. I'll have to give their products a good look-over cause I didn't know about the brand. This might be it, thanks! edit: Kaius used the term EDC tool and I didn't know what it was. Upon looking it up I think "every day carry" is the exactly the concept I'm looking for. That's why I shy from Leatherman's cause they're huge and heavy as hell.
I've owned both (and a SOG multitool). Anecdotally, I thought the Gerber blade was sharper, but I liked the overall function of the Leatherman more. The SOG was a little more complicated than necessary and, in my opinion, didn't really have any advantages over the Leatherman.
I've broken the tips off the Gerber blades before, but usually as a result of doing stuff with it that I really should've been doing with a different tool. I haven't noticed a very distinct difference in my experience, and in the cases where I did break the Gerber blades it probably would've broken the Leatherman ones too. I have noticed that Leatherman blades usually seem less sharp. But I usually carry a SOG knife in cases when I'm carrying my Gerber, so I use that for knifing stuff instead of the gerber.
