The Most Common Beginner Mistakes in Knife Sharpening

Most sharpening mistakes don't come from lack of knowledge, they come from impatience. Once you know them, you generally stop making them. Here are the eight we see over and over, in beginners and in people who have been sharpening for years and still can't get the results they expect.

Mistake 1 – Too much pressure. The logic "more pressure = more material removed = done faster" is technically true, but it costs you precision: the blade sits unevenly on the stone, the angle drifts, and the stone wears out faster than it needs to. The fix: the weight of your hand is enough, let the stone do the work. Rule of thumb: if your forearm gets tired after a minute, you're pressing too hard.

Mistake 2 – Not holding the angle steady. This creeps in especially near the tip of the blade. Sharpening from the handle toward the tip, many people forget to lift the handle slightly as the curve of the tip comes around. Result: the tip gets sharpened at a different angle than the rest of the blade, and afterward feels either sharper or duller than the rest.

Mistake 3 – Using the wrong grit. Starting on a very dull knife with a 6000 grit stone is like working wood with a nail file, technically possible, but it takes forever. Going the other way, using a coarse stone to "refine" an already-sharp knife removes far more material than necessary. The fix: work from coarse to fine, and let the actual condition of the knife decide, not habit.

Mistake 4 – Using a dry stone. Grabbing the stone off the shelf and starting right away sounds efficient but backfires. A dry waterstone cuts unevenly and clogs with metal swarf faster. The fix: soak until no more bubbles rise before you start, and keep adding water as you go. The slurry that forms isn't a mistake, it's part of the process and actually helps the result.

Mistake 5 – Not checking for the burr. Many people sharpen a self-decided number of strokes and switch sides automatically, without ever checking whether enough material was actually removed. The fix: every few strokes, run your thumbnail across the edge. No burr means that side isn't done yet, and it needs to be felt along the entire length of the blade before switching.

Mistake 6 – Switching sides too early. A bit of sharpening, switch sides, a bit more, switch again. Feels productive, accomplishes nothing, because neither side ever gets enough material removed. The fix: work one side through completely until the burr runs the full length of the edge, only then switch. Patience here pays off directly in the test result.

Mistake 7 – Not washing the knife afterward. Sounds obvious, gets skipped constantly anyway. Sharpening releases fine metal particles that have no business ending up on a blade that touches food afterward. The fix: wash with warm water and a drop of dish soap after every sharpening session, dry it off, two minutes of effort for a genuinely cleaner result.

Mistake 8 – Never flattening the stone. Over time, every stone develops a dip in the middle, because you naturally use the same spot most often. Many people don't notice until results suddenly get worse and they can't figure out why. An uneven surface makes it impossible to hold a consistent angle. The fix: check regularly whether the stone is still flat, and correct it with a flattening stone when needed.

The good news

None of these eight mistakes is complicated, and none require expensive gear or years of experience. They're things you learn once and then just avoid. For maintaining your stones in between sharpening sessions, take a look at the Naniwa flattening stone in our recommendations.
