My preferred placement for EDC is IWB, at the appendix. (1 or 2 o'clock) My first FB, was the Gerber Guardian, double-edged dagger. Back in high school. Then I "got into" knives.
I thought, "This Gerber was only fifty bucks - it must really suck."
I traded it away, and for the last 15 years or so, I've been looking for it's replacement.
Tried the Al Mar SERE Fixed, but it was just too big to be comfortable.
Sometimes I carry the Cold Steel Spike Scimitar IWB, with a short tether of cord - short enough so that it retains the sheath in my pants, when I withdraw the blade. I like it better that way.
I really like the ball end, and the size of the handle. I wish the blade had some more metal on it though.
I have went back to the Gerber Guardian. I don't like that it's a double edge, but the adjustable tension sheath is the bomb, and the clip is so good it can be used without a belt, and it holds the sheath tight, for quick draw out of the pants.
The Guardians are cheap, and stealth, and sharp. They can be sheathed in ambidextrously.
Also the rubberized handle on the Gerber is really comfortably against your skin, if you're just wearing a t-shirt, and the dagger is under it.
