I have been storing this for a long time. It is 150mm, but it has a 165mm handle (see photos 3 and 6). As far as I can see with the naked eye, there are no noticeable scratches or rust, but there may be some if you look closely. Please refer to the photos. If you want to buy a set, there are 6 more in stock (7 in total), so if you let me know, I will sell them at a set discount. I have also been storing other products for a long time. *Please purchase only if you understand that returns and exchanges are not accepted. Compared to ordinary stainless steel, it is more resistant to rust and has excellent wear resistance. Molybdenum improves hardening and increases strength and toughness. Vanadium steel has the function of increasing strength and wear resistance. By combining these two, molybdenum vanadium steel is more durable and has a longer-lasting sharpness than ordinary stainless steel. Also, it is an easy-to-sharpen knife, so maintenance is easy. It is a hand-forged knife that is rust-resistant, sharp, and easy to sharpen. The core steel is molybdenum vanadium steel, and the outside is SUS410. The handle is a buffalo horn octagonal handle that is easy to use at home.
