We have had several inquiries over the years to inlay, in one form or another, something into a handle. Elk ivory, eye teeth I believe, comes up the most.
So, with help from a good friend we cast the teeth into resin, and attached it onto the end of the handle.
Doing it this way is not an inlay, but it does allow the ivory to be seen while in a knife block.
All in all. I love it. We will be playing more with this technique with sea shells and things in the future.
