I have'nt sealed it yet.
Testing some dye and boiled linseed oil.
This antler is older and some what dry.
Your's may not need sealing.
I may end up using polyurethane.
I've seen a couple that were just polished and over time they soak up the oils from your hand. That being said, I would think a clear epoxy rather than polyurethane or linseed oil that would likely sink in and change the color.
Awesome blade BTW
I agree, I also have a few and never sealed any of them.The knife I carry to to rendezvous has an axis stag handle and has been in use for many years with no problems
