Has anybody inlayed anything special into a scale? I am wanting to do a restore for a friend and was thinking of puting small crucifix pocket medal into the scales .

I have no idea how to do this and was wondering if anybody has done something like this before. Scale material I was thinking of is either horn or a nice wood. More than likely it would be just a gift display razor, but just in case it would need to be durable as well.
Any thoughts?
