Could someone ID this blade?

That could be a Ken Brock knife... George aka Mercop would know for sure.

Ken Brock and Les George are working on a collab now that looks similar.

or could be a Mickey Yurco Custom

Essentially, the “Mercharness” is a figure-8 shaped harness that is constructed of strong “para-cord” and rubber stops or beads for adjustment.

Overly complicated application for sort of a simple neck knife.
I do not like the ring.

If she is right handed it in the wrong side.

There are simpler, better choices. The Wheeler, Breed, and Sams Kiri come to mind.

BikerDoc , " Overly complicated application for sort of a simple neck knife." , having worn both a MERC harness and a neck knife carried in the standard neck knife carry , I will always choose the MERC harness as it keeps the knife put without sliding around on your chest like a basic loop does.

Works extremely well with an over garment.

Perhaps not for everyone, but a way better option than just looping a piece of paracord around your neck and hanging a sheathed knife from it.

PS. I asked MERCOP last night , and he wasnt sure what the knife was , the image was taken by someone else ( Noah Walt of THurst Magazine I assume ).
