How many years have you used your kitchen knife?

The service life of kitchen knives varies with materials and frequency of use. Generally speaking, a high-quality kitchen knife can be used for many years. If properly maintained, such as cleaning in time after use, keeping dry and sharpening the knife regularly, the kitchen knife can keep sharp and prolong its service life. In China families, the average service life of kitchen knives may be between 5 and 10 years. Of course, this is only a rough estimate, and the actual service life will also be affected by personal use habits and the quality of kitchen knives.
