Price not negotiable. This is a general-purpose santoku knife, but because it's Damascus, I believe it uses blade material comparable to VG-10. The sharpness is already sufficient as is, but sharpening with a finishing whetstone is also possible. If you wish, please choose from the following: Naniwa Hibiki 3,000 Mikawa Oil Kuromaku 5,000 Tsushima Aoto Oka Hana Ootsuki Aiwatani Shobudani Ozaki Mizuasagi (I believe the following whetstones will result in a sharper edge) ----------------------------------------------- Main Specifications ・Integrated bolster ・3 full rivets ・Damascus stainless steel Blade length: 165 mm Total length: 290 mm Weight: 155 grams Hardness: 60±1 HRc ----------------------------------------------- Below is an explanation of VG-10 (V Gold 10) Damascus: "V Gold 10" is a high-grade steel made by Takefu Special Steel Co., Ltd. in Fukui, and is one of the highest-quality stainless steel blade materials currently available. If you choose based on sharpness, carbon steel knives (blue paper steel, white paper steel, etc., also known as Japanese Hagane, or simply Hagane) are prone to rust and require careful maintenance. Stainless steel knives are rust-resistant, but they are not as sharp as carbon steel... or so it was said. However, V Gold 10 is a blade steel that combines the advantages of both carbon steel and stainless steel. It cuts well like carbon steel and is also resistant to rust like stainless steel. Why are V Gold 10 "Damascus knives" recommended? Knives made entirely of V Gold 10 are not very common, as they may lack flexibility or be difficult to heat treat, and are made for some particular users. By layering multiple steels like Damascus knives, it is possible to give the knife composite properties, resulting in a flexible and easy-to-work-with material. The hard core is wrapped in a softer material, making it less likely to bend or break. Heat treatment (quenching and tempering) becomes easier, resulting in a hard and resilient blade (resilience makes it less prone to chipping). #I am also selling this elsewhere, so please understand that I will prioritize the first person to purchase.
