Smith and Wesson boot knife - A dagger (sharp on both edges) type knife that sees little use. I don't like a knife that is sharp on both edges, but I did use it on my pack when I did more hiking. It clipped into the MOLLE of my shoulder strap and was easily accessible for cutting rope or string, and as a last ditch for bear I suppose. (Thank God it didn't get used for that!)
Skeleton boot knife - I never used the knife as a boot knife, instead I inverted the clip and wear the knife on occasion pointing down from my belt. The sheath broke so retention is a concern when carrying the knife. Originally the knife was partially serrated, but I changed it to a completely straight edged knife because I hate sharpening serrated edges.
CRKT Kitchen Carson design M16 - I got this knife from one of my Groomsmen, and carry it every day in my pickup. It stays there and sees a lot of use when I misplace my current EDC knife (which happens more than it should). The knife has a very thin, quick opening blade, and although serrated, I enjoy using it. The only problem I have is that to close the knife there is a secondary 'safety' that has to be disengaged in order to unlock the liner lock. It's still a one-handed knife but takes some getting used to and practice.
Benchmade Grizzly Creek - This is my new(ish) favorite EDC. It comes from the Benchmade Hunt Series and has an awesome blade. I borderline abuse this knife and the edge only gets sharpened about once/month.
Gerber Remix - A good knife with a decent edge. I broke off the tip prying off a hubcap cover, but I liked the hole in this which keeps your hand from slipping when using the knife. Not excellent edge retention, but decent enough to carry for a few weeks
Gerber - I can't remember what this knife is called. It's light, has a locking back, has always been very sharp, and is a pretty good pocket knife. It doesn't have a clip so I don't use it much at all, but when I do break it out I know it'll be sharp.
Kershaw Snap-on - I've had several of this style of knife but I picked this one up from the Snap-on truck. If you ever break any part of it, or it needs sharpened, just hop on the truck, and they'll fix you up. The safety broke on it and it took about 20 seconds for the Snap-on fella to put a new one in. I never had him sharpen it, but I've heard that they'll just hand you a new one instead of taking the time to sharpen it.
