This is a cutter specifically for cutting flooring corners. Thickness adjustment is easy with a simple turn of the dial. It has a resin base for smooth sliding. L-shaped cutter replacement blades can be used. I have used it for several years after purchase, so there is some wear and tear. *Please refrain from purchasing if you are a perfectionist or are concerned about the condition, as this is a used item! *Please make your purchase with a thorough understanding of the item.
