Which will begin to be marred, sliced and cut up with the first use.
Wooden cutting boards are not the germ factories most people worry they are. Cutting board oils and the natural properties of the wood tend to make them non-conducive for growing bacteria. Nothing a good soap & water wash won’t fix (which is why you want the oil - use something like Howard’s Butcher Block oil & conditioner).
Of course, that with normal use - not smearing it with raw poultry parts and then followed up with cutting the veggies. But washing and drying will take care of any bacteria “in the crevices”. They’re far more likely to be a problem when driven into the sliced wood fibers when the knife cuts the surface than they are to be an issue in the depths of an engrave. And it’s easier to use a brush on the laser engrave than the slices and cuts in the surface from using knives on them.
