Yes. All wood cutting boards will show knife marks as wood is a natural material. However, knife marks are a good sign! You should really worry if you don't have knife marks on a cutting board, since that would mean the board is much harder than your knife’s edge, something you would experience with a glass, stone or even bamboo cutting boards which can dull your knives incredibly fast.
Many people forget about the protection of their knives when purchasing a cutting board, and instead focus on keeping their countertop or table safe. Wood cutting boards are the only durable material that will protect both knife and countertop as you prepare meals. While wood cutting boards will show various marks overtime, periodically treating it with food-grade mineral oil will help those marks add character to the board and blend into the natural grain and color of the wood.
