There are 3 types of wooden cutting boards available in the market place - wood face grain, wood edge grain and wood end grain. If you think of a 2 X 4, face grain would be the wide (4") surface of the board, edge grain would be the narrow (2") surface of the board and end grain would be looking at the end of the 2X4 where you can see the growth rings of the tree. OnceCut boards are either edge grain or end grain. These styles of boards are easier on knife blades and show less wear over time.
As the name implies, these boards have the edge grain of the wood as the working surface. These boards are easier on knife blades than a glass or plastic cutting board. Cut marks will appear over time as the blade cuts across the grain of the wood and severs the fibers. However, as with any wood, it can be sanded down and refinished to restore its appearance.
Again, as the name implies, these boards are made using the end of the boards as the working surface. This allows the knife blade to slip in between the wood fibers during a cut. As the blade pulls away, the fibers have a tendency to move back together making the board somewhat self healing. Cut marks will appear overtime, but not nearly to the extent of a face grain or edge grain board. And yes, it too can be re-sanded and refinished to restore its appearance.
