How Often Should You Sharpen Kitchen Knives?
Sharpen when cutting performance indicates the edge needs restoration—not because a universal calendar says so.
The practical answer
Frequency depends on steel, edge geometry, cutting board, technique, use and maintenance. Heavy daily use differs from occasional home prep.
What matters most
Use performance and safe cutting behavior as the signal, then choose an appropriate sharpening method.
