What is an Edge Grain
An edge grain is a pattern found on a wood countertop that marks it as having been created by exposing the staves of the boards used in its construction. A stave is the long side-edge of a cut board. Though countertops created through edge grain construction are typically more durable than products of face grain construction, they're also less durable than products of end grain construction.
Edge grain surfaces are created by boards being attached face to face so as to create a level exterior. The result is a thicker, heavier countertop that has emerged as a popular choice for work benches and other high traffic areas. If you're uncertain as to whether your countertop features edge grain construction, look for the striped, parallel grain lines that serve as a hallmark of this construction style.
