Oiling hilt parts

[Augustus Janus]

I know that generally most people use boiled linseed oil for wood treating such as hilt hardware. Did the Roman troops use this or would they have used boiled olive oil which they commonly had on hand? And if they did is olive oil a good treatment or is linseed so far superior that olive oil should be avoided? Just something I was wondering about as I have a gladius with oak pieces that I want to treat. I have olive oil in the house but no linseed oil.
