It's itame (plain-sawn). 398mm x 205mm x 25mm thick - one-piece board Weight: 779g It's light. Hand-planed finish. Product of Shimokita Peninsula, Aomori Prefecture. Aomori Hiba contains hinokitiol, which has antibacterial, antifungal, and deodorizing effects. It also resists unpleasant odors from raw foods and provides a good cutting surface for knives. Wet with water before use. After use, air dry. Do not use a dishwasher. Do not use bleach, as it will discolor the cutting board. If the cutting board warps, flip it over and it will naturally return to its original shape. The spots that may appear are the hiba oil, which is characteristic of hiba. There are no hygiene issues. Made from the red part of the wood. This is a handmade item by my father (an 80-year-old grandfather) who has been involved in hiba lumbering for many years. Even after retirement, he lovingly finishes hiba in his home workshop, slowly and carefully using a hand plane. This is not a perfectly finished product made by machine, so there may be small scratches, dents, and warps. Please refrain from purchasing if you are looking for perfection. For those who appreciate handmade items. Please refrain from price negotiations. Recycled materials are used for shipping. The last photo is an image of the size (the sea bream is 20cm long). I also have other cutting boards for sale. #cuttingboard #hiba #hibatree #masame (quarter-sawn) #cooking #cookware #brooch's cutting board
