Keeping a Keen Edge
A sharp knife moves through ingredients with minimal pressure, relying on a refined edge rather than brute force. Keeping your blades functional requires a whetstone and a consistent angle, moving from coarse grit to fine grit to hone the steel into a clean, biting line.
Consistency beats speed every time.
The secret isn't how fast you slide the blade, but holding the exact same angle from heel to tip throughout every stroke. If you can't maintain the angle, the stone won't do its work.

Finding the sweet spot
Most kitchen knives thrive at a 15-to-20-degree angle. Use a matchbook stack to visualize the height needed between the spine of the knife and the stone to keep your stroke true.
The method.
Prepare the stone
Submerge the whetstone in water for ten minutes or until the bubbles stop rising, then place it on a damp towel to prevent sliding.
Start with the coarse grit
Place the heel of the knife against the 1000-grit side at your chosen angle. Apply light, steady pressure and slide the blade across the stone in a sweeping motion, moving from heel to tip.
Check for a burr
Run your thumb perpendicular to the blade edge—do not run it along the edge. If you feel a slight snag or rough metal lip, you have successfully formed a burr.
Refine the edge
Flip to the 6000-grit side and repeat the strokes using even lighter pressure. This polishes the microscopic serrations left by the coarse stone, resulting in a smooth, hair-splitting edge.
Test
Slice through a sheet of notebook paper. If the knife snags or tears, repeat the fine-grit sharpening. If it slices cleanly without hesitation, the job is done.
When it doesn't go to plan.
Keep the stone wet; it should always look like it has a thin layer of water on the surface.
Never pull the blade backward against the stone; always move the blade as if you are trying to slice a thin layer off the stone's surface.
Do not overthink the pressure. Heavy-handedness leads to uneven edges.
The ones that keep coming up.
How often should I sharpen?
When the knife starts to crush a tomato skin instead of piercing it cleanly, it is time to sharpen.
What is a honing steel for?
A honing steel does not sharpen. It realigns the tiny, bent teeth of the blade edge between sharpenings to keep the knife feeling fresh.
