Well, you know, the vitamin E oil in there will probably help heal all these battle scars. LOL!
But seriously, pure mineral oil (medicinal variety) is the same thing as medical paraffin. Sounds like you got one that is meant for topical skin application. probably won't hurt your blade, but you might want to get some of the pure stuff for future uses. As Alan suggests, i generally mix in a little sandalwood and kenanga oils. I also brush on with a paint brush, enough t fully cover all surface areas.
