Despite diligent oiling and even applying beeswax, Chowhound jljohn has had two cutting boards split in the last year. A recent Chowhound discussion pondered the question: Should a cutting board be more than two inches thick to ensure longevity?
No way, says GH1618, who thinks the thickness of a board is unrelated to the threat of splitting. That happens when the wood used to make a board wasn't properly aged (that is, dried) or if it was dried at a different humidity level from the one in your home.
But BoardSMITH thinks that the grain of the wood and the manner of assembly have more to do with splitting than its moisture content. "Edge or face grain boards will see more stress from grain direction than end grain boards," says BoardSMITH. "And yes, thicker is better," though two inches should be perfectly adequate.
Thickness isn't an issue with cowboyardee, who's had good luck with cheap, inch-thick end-grain boards. Expensive cutting boards might be worth the money for those who want craftsmanship and beauty, but not to avoid cracking.
