This knife was made for my wife who has a small hand so the handle is slim. This knife is lightweight and suitable for handling vegetables. I love the process of turning fantasy into reality and the sense of accomplishment that comes with seeing the results. About the material: The nails are high carbon steel nails and before forging, I did a heat treatment test. Steel powder contains large particles of nickel, which is where the reflective spots on the blade come from. If you look carefully, you will find that this knife is not pure black, but has many other colors. This is not a camera error, this is real. Once I figure out what's going on, I'll show you the process specifically. Finally, thank you for watching.
