Up until a while ago I did not. I thought it looked much nicer without epoxy. A friend of mine pointed out to me though that if it is a using knife, all those little file marks would be a perfect trap for blood, fat, dirt and god knows what else a skinning knife would pick up. It would be the perfect spot for rust! Hope this helps.
