All Benchmades.a benchmite always, a mel pardue auto always, a 140D (pre nimravus but same design with a 5in fixed blade) most of the time, and an infidel occasionally. I also keep a few of the red box monochromes around in tool boxes junk draers etc. they're handy knives when you don't want to tear up your good stuff.
A Buck 301 pocket knife I've carried everyday since 1979 and a S&W 24/7. Some will badmouth the S&W but it stays sharp and does everything I ask of it. If I lose it I'm not out an arm and a leg either. Same with a Ka-Bar folder I bought from A G Russell for $20.
ooooooh a sebie! Nice... I carry an Emerson CQC7, or a Benchmade Ares, or a Spyderco all stainless Endura, or a Camillus CUDA MAXX (when I want to compensate), or a Benchmade 707, or a ... get the picture? Lots of knives in my rotation, but the Emerson is always there....
While I have a number of knives, including a Benchmade lock-back, the two that I carry on a day-to-day basis are a big Case three-blade stockman pattern (5375 CV), and a Swiss Army knife that is one of the biggest that they make with something like 32 tools on it. It even has a small ball-point pen.
