Fill it up about half full and let the wadding do the rest. This is an easy, safe and economical way to apply camelia oil to edge tools and knives. It is an essential method for caring for chisels, saws, knives shears, secateurs and all those other sharp shiny things that are prone to rust as soon as you turn your back on them.
