What to Look For
Honing ≠ sharpening. Honing realigns the edge (a 5-second pass on a steel rod before each use). Sharpening removes metal to create a new edge (every few months). Most home cooks only need to hone — the edge stays effectively sharp for half a year.
Test before sharpening. The paper test: a sharp knife slices through printer paper cleanly with one downward stroke. A dull knife tears or won't cut. The tomato test: a sharp knife glides through skin with zero pressure. If your knife passes both, don't sharpen yet.

Frequently Asked Questions
How do you know when a knife needs sharpening?
Use the paper or tomato test. If the knife can slice paper cleanly with one stroke and glides through tomato skin with no pressure, it's still sharp. If it tears paper or crushes tomato, time to sharpen.
Can you sharpen a knife too often?
Yes — every sharpening removes a tiny amount of metal. Over-sharpening shortens knife life by a decade. Hone weekly, sharpen quarterly maximum. Most home cooks over-sharpen.
What's the best product to fix this?
We'd reach for the SHARPAL Pull-Through Knife Sharpener. Easy pull-through sharpener for monthly maintenance on budget knives.
How long does this take to fix?
Most solutions are 10-30 minutes of active work. Prevention takes 30 seconds per use.
