The flat groove with a diagonal handle is convenient because it increases the grip area of the front. An interesting design solution would be to combine it with a countertop with a beveled profile. In some cases, the front itself can be fitted with an aluminum profile, which makes the kitchen more durable. The profiles can be in different colors of metal, wood or the color of the door itself. The central groove can be used in the middle of the front, installed on a household appliance (such as a dishwasher).
