Since Josh at South Park Pundit as well as a few other bloggers recently have posted something about their favorite knives, I thought I should jump on the bandwagon. I have always carried a pocketknife, for the past 10 years or so it has been a "Tinker" model Swiss Army Knife, and I also have one of their "Cybertools" which is quite useful. But a few months ago I also started clipping this inside my pocket, and now I feel kind of naked without it.
A Smith & Wesson kerambit. The most useful single-blade, non-gadget-type knife I've ever had. The slot on the blade lends itself well to left-handed opening.
