This is a Deba knife from Masamoto Sohonten. My husband carefully restored this knife, which I received from an acquaintance in a state with black rust. He removed the black rust as much as possible, and carefully polished the areas with deep rust using a file. Therefore, there are some file marks and signs of use, but the sharpness is excellent, and it is perfectly usable. As expected of a Masamoto knife, the blade enters and bites into food well, making it suitable for everything from preparing fish at home to more本格的な料理 (本格的な料理 - more serious cooking). ⚫︎Size and Condition Blade length: Approximately 20cm (measured by an amateur) Handle: Wooden handle (with scratches and dirt from use) Accessories: Knife only (no box or saya) The blade has been sharpened and is ready to use upon arrival. There are scratches, small marks, and sharpening marks typical of used items. *Please refrain from purchasing if you are looking for a perfect, beautiful item or are concerned about minor details. *Please also check the photos for the condition. ⚫︎About Masamoto Sohonten Masamoto Sohonten is a long-established Japanese knife shop that has been in business since the Edo period. It is known as a prestigious brand of Japanese knives, loved by many professional chefs. The steel is of high quality, and the knives are characterized by their longevity, "responding the more you sharpen them." I think this knife is also suitable for those who want to sharpen it and cultivate it to their liking.
