Not sure what it has to do with it. A knife handle isn't a rifle stock. I have been to BRKT and own at least a half dozen of them.

I stabilize my own wood and have handled up plenty of knives. What I use on it depends. Sometimes a simple paste wax is all you need. Sometimes BLO and paste wax. Sometimes stain and or poly. Shellac is one thing I haven't used on a knife handle.

Would almost seem like using the stain with the poly already in it, which I don't like. But, hey, whatever works. I am just stating what I do/ don't do...
