Demarle Différence^® Knives are ergonomically designed to fit in your hand. Notice how the curve on the handle fits perfectly in your palm. The Demarle Différence^® design gives greater control. It does not put pressure on your wrist or hand when using. Demarle Différence^® Knives are perfectly balanced to yield a more even cut. Demarle Différence^® Knives are fully forged. They are made from one piece of high-quality stainless steel honed down instead of stamped for a lifetime of resistance and efficiency. Demarle Différence^® blades are tempered. This is a method of heating steel that smoothes out imperfections and makes the blade extremely strong.
