There are stains on the handle due to long-term storage (see photo 10). *Please note that returns and exchanges are not accepted. Please purchase only if you understand this. Stainless steel materials generally use molybdenum steel, but all others offer a high-quality sharpness and durability. Gin-san steel (Silver #3 steel) has both sharpness and durability, and is also rust-resistant, making it a highly-regarded material among chefs. The handle uses a buffalo horn octagonal handle, which is very easy to use and designed to fit comfortably in the hand. The octagonal handle is said to be easy to use, so much so that it is familiar to chefs.
