I hand forged this knife, using 52-100 ball bearing steel, and did all of the handle, bolster, and end piece work on it myself. The handle is solid cocobolo, and the bolster and end piece are solid copper, which will turn a darker tint as time goes by. It comes with a lifetime warranty, and I guarantee that it will stay sharper, for longer than any knife you have tried before. It will change color however (to a dark blue/gray) which I think is pretty cool, it does this because the 52-100 steel is NOT stainless, and is designed to be used more for reliability, durability, and hardness. As always id like to mention that I do make custom knives (shape, size, steel type, handle type, guard type, etc) , feel free to message me about what you would like, and I can make it for you.
