The cutting board is made of ash wood. The ancient Japanese yakisugi technology has been used to obtain a uniform and permanent black color - wood is burned to increase its durability, resulting in a charred protective layer on the surface of the wood. Square cutting boards have a curved longer side, and a recessed groove on the shorter side, which makes it easier to pick up and hold the product from the board. Round cutting boards have a curved entire edge. The cutting boards are made of a single plank (i.e. no glued wood is used).

A special cutting board oil has been used for the finish, which consists of natural oils and waxes and is safe when in contact with food. The oiling creates a permanent waterproof coating on the cutting board.

The cutting board does not require additional oiling or any other maintenance during long-term use. The cutting board can be washed by hand under running water, washing in a dishwasher may damage the product. The cutting board is not fireproof.

Like any cutting board, this cutting board will leave knife marks when cutting with a knife - under normal use, they do not penetrate the char layer covering the wood. Cutting with forceful sawing movements and/or a serrated knife may expose the wood beneath the char layer. When cutting with a sharp knife, a small amount of soot may remain on the knife blade - this is safe and will not spoil the product.

Each cutting board is handmade from natural material and therefore unique, which is why it may differ from the product image. Cutting boards may have cracks/splitting, and the edges/corners may also be slightly uneven. These are not defects - cracks/splitting are natural when burning wood, and the wood also burns unevenly. As a result of fiddling, the cutting board may warp slightly (up to 1-2 mm).
