The best cutting boards use end-grain for this exact reason. It’s not just a decorative thing. The direction of the wood grain directly determines how quickly the board will dull your knife. Wood is made of two main parts: A hard fiber, and a soft filler in between each fiber. The hard fiber is what dulls your knife when you cut.
Imagine cutting on a tightly packed bundle of really tiny straws. If you cut across the bundle, your knife will be cutting into each straw, dulling in the process. But if you cut on the end of the bundle, the knife blade will slide between the straws instead of cutting them.
The straws will last longer when you’re cutting on the end (because you’re not cutting them) and your blade will last longer (because it isn’t cutting the straws). And an end grain cutting board is essentially cutting on the end of the straw bundle.
