You can put it on a Tek Lok. I do carry my ED on my belt using Tek Lok.
I'd say it's ok knife to carry around. It would help wrapping the handle with paracord, though. The bare skeletal handle isn't much comfortable for me. With paracord wrapped, the grip's much better. Handle length is about right.
The blade is kinda small (i.e. short), but considering it is so-called neck knife, not much problem there I guess. Blade's not as thick either. About 0.1" I think. (I haven't measured it)
Overall, it's kinda lengthy, with the handle offers almost full length I say. Kinda bothersome to carry as a neck knife for me. Also, I don't carry it horizontally on my side, because of its length. I carry it at small of back. (I usually fumble around when I try to put it back to the sheath)
The blade itself is the same length and shape as that of PT.
I haven't put it through a hard use (most my knives don't). Thus I can't say how tough it might be. It's good for small cutting tasks. Edge holding is good.
Comparing to other neck knife / small knife, its long handle is a plus in handling. It offers good grip. But, also, it makes ED bigger and harder to carry around than most neck knives. It's skeletal handle needs some help like additional paracord wrapping.
Currently, I'm considering to get BM211 for my small fixed knife. ED is fine, but I want something with thicker blade. BM211 offers thick blade of D2 steel and a wooden handle.
Do I recommend ED for you? I don't know. I would have, if it's a year ago. Not because ED's inferior in anyway. It just doesn't quite fill my need.
If you want light, small fixed knife to carry, ED is a good choice.
