Quick Summary
- Angle: Shun sharpens its double-bevel knives to 16 degrees per side; keep that angle.
- Hone gently with a few light strokes per side before use; don’t hone for minutes.
- Sharpen on whetstones: 1000 grit to sharpen, about 6000 grit to refine.
- Avoid pull-through carbide sharpeners and coarse grinding, which can chip hard Shun steel.
- Not confident? Shun offers a free sharpening service for its knives.

Shun knives are made in Seki, Japan, from hard steels such as VG-MAX. That hardness lets them take a very sharp edge, but it also means they need gentle, careful sharpening.
This guide covers honing, whetstone sharpening and what to avoid. For background on the brand’s lines, see our Shun knives review.
Honing vs Sharpening
| Honing | Sharpening | |
|---|---|---|
| What it does | Realigns the existing edge | Removes metal to create a new edge |
| Tool | Honing steel or ceramic rod | Whetstone or quality sharpener |
| How often | Before most uses | Every few months for home cooks |
| Time | A few seconds | 10–30 minutes |
Our older guide said to hone for 5 to 10 minutes per side. That’s far too long; a few light strokes on each side is enough.
Shun’s 16-Degree Angle
Shun’s double-bevel kitchen knives are sharpened to 16 degrees per side. That’s slightly wider than Wüsthof’s 14 degrees but much finer than many budget knives, and the hard steel holds it well.
Shun’s own 3-piece whetstone system pairs a 1000/6000 combination stone with a stand that has a built-in 16-degree angle, which shows the angle the brand recommends.
How to Hone a Shun Knife
- Hold the honing rod vertically with its tip on a damp towel on the counter.
- Set the blade at about 16 degrees to the rod.
- Draw the knife down and toward you, heel to tip, with very light pressure.
- Alternate sides, three to five strokes each.
- Wipe the blade to remove any fine metal particles.
Use a smooth or fine ceramic rod, or Shun’s own honing steel. Coarse, grooved steels can damage hard Japanese edges.
How to Sharpen a Shun on a Whetstone
Step 1: Prepare the Stone
Soak a water stone until it stops releasing bubbles, usually about 10 to 15 minutes, then set it on a damp towel or holder so it can’t slide. Splash-and-go stones only need wetting.
Step 2: Find the Angle
Lay the blade on the stone and raise the spine until the edge sits at about 16 degrees. An inexpensive angle guide clipped to the spine helps beginners keep it consistent.
Step 3: Sharpen the First Side
With the edge facing away from you, push the blade across the 1000-grit side in smooth strokes, working from heel to tip. Keep light, even pressure.
Continue until you can feel a tiny burr along the opposite side of the edge with your thumb, brushing from spine toward edge, never along the edge.
Step 4: Sharpen the Second Side
Turn the knife over and repeat with the same number of strokes. Aim for an even burr along the full length of the edge.
Step 5: Refine and Polish
Switch to the 6000-grit side and repeat on both sides with lighter strokes. Finish with a few alternating single strokes to remove the burr.
Step 6: Clean and Test
Rinse and dry the knife, then test it on a sheet of paper or a ripe tomato. A sharp Shun should glide through with almost no pressure.
Stropping for a Finer Edge
After the finest stone, a few passes on a leather strop, spine first, can make the edge even keener. Keep the blade nearly flat and use very light pressure.
Stropping also removes any last trace of the burr. A strop loaded with a fine polishing compound works especially well on hard Japanese steel.
Which Grits to Use
| Grit | Use |
|---|---|
| 300–400 | Repairing chips or a badly damaged edge only |
| 1000 | Regular sharpening of a dull edge |
| 3000–6000 | Refining and polishing the edge |
Our older guide told beginners to start on a 300-grit stone, which removes metal very fast and is only needed for repairs.
For more on choosing stones, see what grit whetstone to use.
Single-Bevel Shun Knives
Some Shun knives, such as traditional yanagiba and deba knives in the Pro line, are single-bevel. Sharpen the beveled side at its existing angle, then lay the flat back fully on the stone for a few strokes to remove the burr.
Our older guide said to sharpen single-bevel blades “at 45 degrees to the stone”. Traditional guides do hold the blade at about 45 degrees across the length of the stone, but the bevel itself should lie flat on the stone surface, not be tilted up to 45 degrees.
Signs Your Shun Needs Sharpening
- It slides on tomato skin instead of biting straight in.
- Onions crunch or tear rather than slicing cleanly.
- Paper tears instead of slicing smoothly.
- Honing no longer helps for more than a day or two.
If honing restores the edge, you don’t need to sharpen yet. Sharpen only when honing stops working, which saves metal and extends the knife’s life.
Repairing a Small Chip
Hard steel can chip if it hits a bone or a hard board. Small chips can be removed by sharpening on a coarser stone, around 400 to 1000 grit, until the edge is even again, then refining as normal.
Large chips or a broken tip need more metal removed and are best handled by Shun’s service or a professional sharpener. Don’t try to grind them out on an electric grinder.
What to Avoid
- Pull-through carbide sharpeners, which tear rather than grind hard steel and can chip the edge.
- Coarse grits for routine sharpening.
- Heavy pressure; let the stone do the work.
- Electric grinders not designed for 16-degree Japanese edges.
- Testing sharpness by running a finger along the edge.
Shun’s Free Sharpening Service
If you’d rather not sharpen yourself, Shun lists a free lifetime sharpening service for its knives on its website. Check the current terms and shipping instructions before sending knives.
Safety
The UK Health and Safety Executive’s guide to safe knife use stresses training in safe sharpening methods and keeping knives sharp, since dull blades slip. Keep your fingers clear of the edge and work slowly.
Keeping a Shun Sharp Longer
- Use wood or soft plastic boards.
- Hand wash and dry straight after use.
- Avoid bones, frozen food and twisting cuts.
- Store in a block, on a magnetic strip or in a saya.
Cleaning habits matter too. As Wüsthof’s guide to cleaning knives notes, dishwashers and soaking in the sink damage edges, and the same applies to Shun.
For a general walkthrough that works on other knives too, read how to sharpen kitchen knives with a stone. Good examples of knives this method suits include the Shun Classic 8-inch chef’s knife.
