I know there are some cool clips/loops on knifekits.com that get the job done, but aside from those and a Tek-Lok, is there anything else out there than folks are using on Kydex knife sheaths that really does the job well?
What kind of carry ya wanting to do? I'm not a fan of the TKs because they are so big. For a centerline small knife (Clinch Pick) they work well, but anything much bigger hangs out like a Safariland duty holster.
I've gone to IWB and pull-the-dot belt loops(BladeTech style) for anything over about 4" OAL. I've also made a few serviceable J clips.
