Utter nonsense, but a few folks have mentioned that. Even going so far as to chop on another cheap board on top of the Gowanus Furniture board. I'm not trying to shamelessly promote the cutting boards, but they are finished very well. Incredibly smooth, and using it will gouge it up a bit.

But that's ok.

I happen to think they look better with some wear, but if you are concerned about beating it up a bit, all Eagle and Kentile boards include one resurfacing in the bank, for use at a later date. Get it to me, I'll clean it up, good as new, and ship it back to you, free of charge. 

So don't worry. Chop and mince vigorously on it. Just please don't put it in the dishwasher.
