Native Alaskan Fishing Implement #6

We acquired about a dozen of these beautiful Native Alaskan pieces of fishing equipment that we intend to use as pendants or other jewelry.  This appears to be a gorgeous fish hook or spear tip, made of some sort of bone.  This piece has a primal curve to it; almost like a long tooth which has been shaped and carved to make it sharp.  

This beautiful piece has a large hole through the middle of it, large enough to accommodate a decent sized cord.  There's also a hole drilled into the wider end of the pendant; we're honestly not exactly sure what it is for, but likely had something to do with effective fishing.  The pendant measures 3 inches long, and 16 mm at its widest point.  It weighs 9.9 grams.
