A truly dull knife is more than just frustrating; it’s dangerous. When your blade has lost its bite, or worse, developed unsightly chips, it clearly indicates that honing is no longer good enough; you need to actively take away material and reform the cutting edge. Fix a Dull Edge Removing Chips is a fundamental skill for any serious cook, taking a seemingly ruined blade back into a precision cutting tool by way of restoring its original geometry.

Chip Depth: Assessing the Damage
Before beginning, take a close look at the blade: small nicks or an edge that is generally rounded calls for less vigorous grinding. With deeper chips, more time and material must be taken away.
- Expertise: It is not simply a matter of removing the chip but of putting a new, consistent apex the very tip of the cutting edge above the deepest point of the damage. This generally involves grinding down the entire edge slightly in order to maintain a uniform profile, which is so critical for the Fix a Dull Edge Removing Chips procedure.
The Right Tools: Coarse Grit First
For serious dullness or chips, you have to begin with a coarse sharpening stone, generally in the range of 200-grit to 400-grit. The aggressive grit takes off metal quickly and efficiently.
- Authoritativeness: It is useless to try to sharpen a really dull or chipped blade with fine grit; it will take way too much time and effort without ever truly re-forming the edge. Any respected professional knife maker always states that one must start coarse in order to establish the new geometry. Waterstones provide the perfect lubrication when properly soaked for this process, preventing overheating and assuring effective material removal.
Restoring Geometry: Consistent Angle is Key
This is where the true sharpening skill comes in: you need to be able to hold a knife at your desired sharpening angle let’s say 15 to 20 degrees per side for Western knives consistently while moving the blade across the stone.
- Experience & Trust: Concentrate your efforts on grinding away the shoulders of the blade until the entire cutting edge intersects with the stone above the deepest chip. The motion should be smooth and controlled, using the full length of the stone. You’ll know you’re making progress when you see a consistent slurry forming and, eventually, feel a burr (a tiny wire-like edge) along the opposite side of the blade. The burr signals that you’ve ground all the way through and established a new apex essential for fixing a dull edge by removing chips.
Refining the Edge: Progressing to Finer Grits
Once the new geometry has been set and the burr is present, start moving up to finer grit stones 1000, 3000, 6000-grit to refine the edge and remove the burr, resulting in a razor-sharp, mirror-polished finish.
