I searched for 'refinishing an old cutting board', but didn't find anything. Sorry if I'm asking a question that's already been asked & answered. I found an old end-grain cutting board at the local thrift shop for $4 and thought I could give it a good home. It has lots of knife cuts, no cracks or splits, looks dry, should I do anything beyond washing and oiling it? I'm not sure the kind of wood, any ideas? Also found a Chef's Choice 310 for $4, a good day at the thrift shop!
