I don't knap but I do collect knapped items from friends. Here is my knife collection. I'll try to name a few of the makers.

top left, Mickie Lotz,
center right rhyolite blade, James Parker
top coyote jawbone, Wm. Blalock(bought at Friendship Indiana).
Coyote jawbone in Becca Parker braintanned sheath with quillwork, Eddie Parker
Forked antler under braintanned, Dana Montgomery.
Long antler on right side, David Knight.
The others are not signed and I don't remember.
