The Pro 'S' line is for semi-professional to professional kitchens. These knives will last a lifetime, due to the high carbon steel they use in Germany to make then and the ice-hardening process that keeps them sharp, stay sharp and durable, and remain chip and rust-free. The straight full bolster is great for balance and keeps your grip tight and comfortable. The German knives don't come much better than these! Room for your own favorite steak knives, too!
