The Professional Line knives are especially made for kitchen professionals. The incredible high quality of the blades is a result of a thermal treatment which consists of hardening (heating the blade), sub-zero (cooling from 50 to -196 degrees), and tempering (increasing the steel elasticity) for a longer and more efficient life. The anatomical and ergonomic textured polypropylene handle with antimicrobial protection is directly injected on the steel bolster, ensuring a comfortable, safe use. The Line is certified by the National Sanitation Foundation (NSF), an organisation internationally recognised by its consultancy, inspection, and training practices aimed at guaranteeing the sanitation of food, water, air, and the environment. Easy to clean, these items are dishwasher safe.
