Thank you very much for viewing from among many items. Item ① has been used about 10 times. Items ②, ③, and ④ show signs of use, but are still usable. There are no chips, and I think all four knives will perform well with sharpening and maintenance. ① Sakai Ichimonji Mitsuhide (Yanagiba Knife) Blade length: 200mm Total length: 340mm Photos 2-6 ② Sakai Minamoto Taihei (Yanagiba Knife) Blade length: 195mm Total length: 335mm Photos 7-11 ③ Sakai Sadamori (Yanagiba Knife) Blade length: 200mm Total length: 340mm Photos 12-16 ④ Sakai Minamoto Taihei (Deba Knife) Blade length: 150mm Total length: 285mm Photos 17-20
