I saw this clip on a knife in my archery instructor's quiver, and another person today, and from the looks of it, it's a 4.5+" 3.5+" knife, black handled (this all in a week, don't ask me why I didn't ask either of the 2 people).
My archery instructor also had a smaller black knife (probably 4" 3") that looked a lot like a Leek, even the clip, but the clip came to the end up of the handle (tip down).
Anyways, if no one can help, I'll just ask my instructor next week when I next see him.
(Sorry about the size of the image, I figured it would be smaller when hosting it, and I have no idea how to make thumbnails here.)
