The number of layers in the steel affects the price, with more layers requiring more folding work and resulting in a higher price point.
Zack uses a specific twisting technique to create star-like patterns on the steel, with too much twisting risking shearing of the layers.
After forging and heat treatment, the blade undergoes grinding and handle shaping, with materials like Arizona Ironwood costing significantly more.
The final step involves etching the blade to reveal the Damascus pattern, ensuring the knife is sharp and ready for sale.
