Nice. Looks like a hafted knife to me. Like KentuckyHeadhunter said it probably had a bone or antler handle but don't rule out the wood handles. Im sure wood was used for lots of handles and many other uses but its decomposed so there isn't much proof.
Ive found 3 antler handles and 1 had the blade still in place.
Here you go. The end of the handle has been drilled. Not sure why but a guess would be after the point was secured with pine pitch at the hafted end another glue was poured from the back of the handle.
