I bought http://www.kabar.com/knives/detail/30 recently treated the sheathe with neastfoot oil, i had been careful to keep the oil out of the inside of the sheathe. My question is if i did oil the inside would the neatsfoot degrade the blade? I would like to do this because , this way i can store it in the sheathe and have a layer of oil on the blade. Instead of having to store it outside the sheathe,nwhen not in use for i have been putting a light coat of militec1 on it and putting it back in the carboard sheath it shipped with per the instructions, would rather store it in the sheath if i can.
