That also crossed my mind. It's nice to have an 'easy clean' tool to use over time. But when it needs refinishing you have to wonder how much polyurethane was eaten. Best to have no finish at all and just deal with having to wash it well each time and let dry. I guess there is an organic oil to wipe it down each time after cleaning to keep the wood sealed. Much like many wood products that just need oiling now and again. It would be easier to hang on to as well while mashing things with no finish. I always wonder how much Teflon I've eaten with the coated frying pans I've used over the years.
