The most common type of kitchen island tops and countertops has edge grain orientation. Boards are positioned on their sides and glued, so that the work surface of the wood countertop is formed by the narrow edge. The pieces may have extended lengths with no joints. You might also come across strips in random lengths that are finger jointed. Compared to kitchen island tops and countertops with face grain orientation, edge grain is typically more durable and functions better as a worktop. Butcher-lock countertops and kitchen island tops made of edge grain orientation can also be less pricey than other countertops. Large areas such as a long kitchen countertops or kitchen island top are suitable for edge grain wood countertops.
