You should treat your wooden utensils and cutting boards every few months or even more often if thay are used a lot with olive oil. Coat them with olive oil and allow it to soak into the wood. It will help preserve them. Also when washing them don't put them in the sink to and have them soak while you do the other dishes. Wash them immediately. Don't let the wood stand in water as it dries the wood out and will warp and crack it over time.
