To what extent are the DIN test’s 60 cycles comparable to real-life use?
The DIN test is designed to quickly and reproducibly dull a knife’s blade. The speed at which a knife used in a kitchen environment becomes dull varies wildly and depends on numerous factors, such as the produce cut, the cutting surface, pressure, technique, frequency, cleaning, storage etc.
Using the ZWILLING SharpBlock to regularly sharpen your knives and treat them well generally keeps them sharp for many years and prevents the need for additional sharpening.
