Are there any type of polish, lube, or oil to put on a fixed blade knife to make drawing the knife from a kydex sheath easier? It's like pulling teeth for one of my newest additions. I bought two of the same model knife with different production dates, and one seems to have a light film of lubricant on it which smooths the draw, the other one is completely dry. So do high end production manufacturers coat the blade to make drawing easier? Thanks.
