7, Granton Edge, Fibrox Handle, Santoku Knife Stamped Knife: A stamped knife is cut into a shape from a cold rolled piece of steel and then ground, tempered, and sharpened. It requires many less steps than forging and results in a lighter, narrower blade. Stamped knives are easier to produce and therefore less expensive. They perform very well and can approach the quality of a forged blade (but not the weight or feel).
