Personally I always carry a Gerber Evo(and sometimes a second on a necklace) and a Gerber Mini Paraframe. When in bad neigborhoods this goes in my left boot.
Not sure what make it is, dad bought it in the 70's. It is marked "Explorer MM-V" on one side and "Made in Japan" on the other.
Of course, if I could carry any knife I wanted this would be on my belt for the sheer coolness factor, even though it is impractical for most things.
The two smaller knives are eating knives that piggyback in the sheath, and the shell is a .270 winchester round used for comparison.
My father brought this back from Pakistan. It is handmade, blade is 8", OAL is 13 3/4", it is VERY sharp. Blade is 3/8" thick along the spine, narrowing toward the point. (It actually says "Gurkha Army", there is a scratch that makes the "U" look like an "O")
Sorry for the gratituous knife pics.
