First post here. This is my main /out/doors knife (not my picture). The handle comes with no sealant, finish or anything of the sort. Will treating it with just polyurethane protect it? Thanks!
Yeah its just personal preference. You can also use boiled linseed oil. Or vegetable oil (blade and wood) or fix'n wax (blade and wood). Or you can really use any furniture / wood sealant you want.
I use coconut oil or really any oil I run across since I always cleaning them and reoiling on a regular basis. I use lard and coconut oil for my cast iron so there's always a oil basting brush in my kitchen on the wall handy.
