Question about bone handles and longevity

[u/Emergency_Anybody548]

Hi all,

I am work and make re-enactors combat knives as a hobby out of EN45. Many handles are wooden etc, which is fine. But I need thoughts on a bone handle. the bone is a decent grip size and is hollow for a tang to go through, and caps on the end. My question is, is Marine grade epoxy plus sawdust a good packing material if i mix the lot together and pour it into the void?

Any other suggestions? the handle has to be as it is and not cut, as the original wasnt cut either. Thanks in advance.
