Why Your Kitchen Knife Feels Dull (And How to Fix It Without a Sharpener)

Published: March 06, 2026

Most 'dull' knives aren't—they're just dirty or misaligned. 1. Clean the blade with vinegar + baking soda to remove micro-residue that dulls performance. 2. Use a wooden cutting board—glass or stone chips the edge. 3. Always cut on a stable surface; a slipping board damages the tip. 4. Store in a block or sheath—tossing it in a drawer causes nicks. 5. Use the 'paper test': if it can slice a hanging sheet of paper cleanly, it's sharp. No tool needed.
