Shun knives are some of the sharpest and most elegant Japanese blades you can own—but keeping that razor edge takes proper care. Unlike German knives, Shun blades are made from VG-MAX steel and require a precise 16-degree sharpening angle. In this guide, you’ll learn exactly how to sharpen and maintain your Shun knives using the right whetstones, techniques, and best practices.

Key Notes Before Sharpening Your Shun Knives
- Use a quality whetstone set: start with 1000-grit for sharpening, finish with 4000–6000 grit for polishing.
- Always maintain a 16-degree sharpening angle on both sides of the blade.
- Practice on less expensive knives before sharpening your Shun.
- Avoid electric sharpeners, which can damage VG-MAX steel.
- Use a honing steel between sharpenings to realign the edge.
Essential Tools and Techniques for Sharpening Shun Knives
To sharpen your Shun knives correctly, you’ll need:
- Whetstones: A dual-grit stone (1000/6000) covers sharpening and polishing.
- Angle Guide: Helps beginners hold the blade at 16°.
- Honing Steel: For weekly edge maintenance.
- Towel and Water: Keep your stone wet and your station safe.

Step-by-Step Method: Sharpening a Shun Knife
Question: What’s the exact process for sharpening a Shun knife at home?
- Soak your whetstone for 10–15 minutes (if not, use a splash-and-go method).
- Set the sharpening angle at 16° using an angle guide or practice strokes.
- Sharpen with even, edge-leading strokes along the entire blade.
- Check for a burr forming on the opposite side.
- Flip and repeat on the other side for balance.
- Polish with a 4000–6000 grit stone for a mirror edge.
- Hone lightly with a honing steel to finish.

Best Practices for Maintaining Your Shun Knife’s Edge
- Hone regularly: Daily if you cook often, weekly if occasionally.
- Sharpen your Shun knives approximately every 2–3 months, depending on usage.
- Clean properly: Hand wash and dry immediately—never dishwasher.
- Use soft cutting boards: Wood or composite boards prevent edge damage.
- Store safely: Knife blocks, saya covers, or magnetic strips.

Common Mistakes to Avoid When Sharpening Shun Knives
These are the mistakes that can permanently damage your Shun knife if not avoided:
- Wrong angle: Anything above 16° dulls the edge faster.
- Skipping grits: Don’t jump from coarse to fine—each step matters.
- Using pressure: Let the whetstone do the work.
- Electric sharpeners: These can chew through your Shun’s hard steel.
- Neglecting burr removal: Leaves your edge ragged and uneven.
How We Tested Shun Knife Sharpening Techniques
We tested three Shun models:
- Shun Classic Chef’s Knife (8″)
- Shun Premier Santoku (7″)
- Shun Sora Utility Knife (6″)
Test Protocol: We dulled each knife by cutting rope, sharpened it with a 1000/6000 whetstone at 16°, and evaluated sharpness by slicing tomatoes and paper.
Result: All knives regained a razor-sharp edge with proper burr removal and polish.
