Yes, a high-quality knife can easily last a lifetime, and even outlive you, provided it is made with good steel and treated with basic care. How long it lasts comes down to daily maintenance, how you sharpen it, and what you use it to cut.

These surfaces are harder than your knife's steel. So every time your blade contacts them, it suffers microscopic edge deformation, chipping, or even rolling.
How long a kitchen knife lasts depends largely on how it is made, how often it is used and how well it is cared for.

Rule #2: Don't drop your knife on the floor.
