Amazon has the Leatherman h502 folding knife with sheath for $28.59, with a $5 rebate. Leatherman makes some awesome multi-tools, and their knives are no slouches. It is 420 HC steel, which is not exactly a super steel, but still has great performance at a low price.
The h502 has a can opener, carabiner/bottle opener, bit holder, and bit driver. I have a previous version of this tool, and have been pretty happy with it.
