An ideal knife for cutting fruits and vegetables. North knife series is made in German steel quality with a hardness of 56 +/- 2 rockwell. Robust and good knives that you will enjoy for many years. If you want to sharpen the knife after some time, we recommend an angle of 20 degrees with cutting steel. The handle is made of ash with an ergonomic and comfortable design that fits well in the hand. Foods with high salt and oxygen levels want to make your knives less sharp, so always rinse the knife after use. Then clean with a brush and detergent. Dishwasher will over time make a steel knife dull and the wood handle will slow down more quickly.
