[Bonetools] Usewear on a bone tool

[Christian Gates St-Pierre]

Hello everyone,
I have recently observed some unusuall usewear on a bone tool and I would ask for some opinion as to what material/function could best explain such microwear (see attached images, respectiveley taken at 50x and 100x). From my experience I think it cannot originate from contact with leather, bark, or plant fibers. Any idea?
Thanks in advance and all the best to erveryone for 2015!
Christian
