You shouldn’t lubricate wooden tools with oil as it soaks into the wood and eventually causes it to soften. Use wax. (Candle stubs work fine for this and are useful for lubricating woodscrew threads.)
For use on metal hand tools I favor plain old mineral oil. (Yes, the stuff that is sold as a laxative.) It’s cheap, it works well as a lube and rust preventative and, unlike 3-In-1, it doesn’t stink or get gummy. Save the 3-In-1 for your bicycle chain, which is what it was designed for.
