Serrated knives are the unsung heroes of the kitchen. Whether slicing crusty bread, ripe tomatoes, or delicate pastries, they deliver clean, precise cuts without crushing soft textures. However, their jagged edges can make sharpening tricky — unless you know the right technique.
At Hospitality Connect, we understand that maintaining your knives is essential for performance, safety, and longevity. In this guide, you’ll learn how to sharpen a serrated knife, what tools to use, and how to care for your Victorinox, Wüsthof, and Global knives for years of professional-grade performance.
🧠 Why Serrated Knives Are Different
Unlike straight-edge knives, serrated blades feature scalloped “teeth” or gullets that bite into the surface of food, reducing friction and creating a cleaner slice. This design means they stay sharp longer — but when they do dull, sharpening must be precise.
Common Uses for Serrated Knives
-
Cutting crusty bread or baguettes
-
Slicing soft fruits like tomatoes and peaches
-
Trimming cakes and pastries
-
Carving roasts or meats with crispy outer layers

⚙️ What You’ll Need to Sharpen a Serrated Knife
To sharpen a serrated knife safely and effectively, you’ll need:
-
Ceramic Sharpening Rod or Honing Steel — ideally tapered to fit each serration.
-
Soft Cloth or Towel — to stabilise your knife during sharpening.
-
Leather Strop or Fine Sandpaper (Optional) — for polishing and refining the edge.
💡 Pro Tip: Match the rod’s diameter to the size of your knife’s serrations for consistent results.

🔪 Step-by-Step: How to Sharpen a Serrated Knife
1. Identify the Beveled Edge
Examine the blade closely — one side will be beveled (angled), while the other remains flat. Always sharpen only the beveled side.
-
Victorinox and Wüsthof knives have a visible bevel.
-
Global Knives, made from single-piece stainless steel, may have a subtler curve — use bright lighting for visibility.
.
2. Use the Sharpening Rod
-
Insert the ceramic rod into the first serration near the blade base.
-
Match the rod’s angle to the bevel (typically 13–17°).
-
Slide the rod forward and outward with light, controlled pressure.
-
Repeat two to three times per tooth.
Continue along the entire blade, maintaining the same motion and angle. Patience ensures uniform sharpness and prevents tooth damage.
3. Remove the Burr
After sharpening, a small burr (metal ridge) may appear on the flat side.
-
Lay the knife flat on a fine stone or leather strop.
-
Gently draw the blade backward once or twice to smooth the burr.
This final polish preserves cutting precision and reduces drag.
4. Clean and Dry
Rinse your knife under warm water and dry immediately with a soft cloth. Even stainless steel can corrode if left damp.
🧽 Tip: Use Hospitality Connect’s professional cleaning accessories to maintain blade hygiene between uses.
🧰 Caring for Your Serrated Knife
Proper care extends the life and performance of your knives:
✅ Do:
-
Use wooden or plastic boards (never glass or marble).
-
Hand wash only.
-
Store in a knife block, sheath, or magnetic rack.
-
Lightly hone every few months.
❌ Don’t:
-
Chop or twist with serrated blades.
-
Force cuts — let the serrations do the work.

⚡ How Often Should You Sharpen a Serrated Knife?
Because serrated edges stay sharp longer than straight blades:
-
Home chefs: Every 12–18 months
-
Professional kitchens: Every 6–12 months, depending on use
In between, maintain alignment with a fine honing steel or ceramic rod.
🪶 Pro Tip: Protect Your Investment
-
Apply food-safe oil after cleaning to prevent oxidation.
-
Never store knives loosely in drawers — it dulls edges and poses injury risks.
-
Rotate knives for different tasks to reduce wear.

🔍 FAQs: Serrated Knife Sharpening
1. Can you sharpen a serrated knife at home?
Yes, with the right tools — a ceramic sharpening rod or tapered steel. Always sharpen the beveled edge and avoid aggressive pressure.
2. How often should I sharpen a serrated knife?
Most serrated knives only need sharpening every 12–18 months (home use) or 6–12 months (commercial kitchens).
3. Should I sharpen both sides of the blade?
No. Only sharpen the beveled side of a serrated knife. The flat side should remain untouched, except for light deburring.
4. What’s the best tool to sharpen serrated knives?
A ceramic sharpening rod or tapered honing steel works best, fitting perfectly into the serrations without damaging the blade.
5. Can I use an electric sharpener?
Avoid it. Electric sharpeners can flatten or deform serrations. Manual methods are safer and more precise.
6. Where can I buy professional sharpening tools?
Visit Hospitality Connect for Australian-standard sharpening rods, steels, and knife care accessories.
7. What’s the difference between honing and sharpening?
Honing realigns your blade between uses, while sharpening removes material to recreate the edge. Serrated knives typically need more honing than sharpening.
8. Can dishwashers dull serrated knives?
Yes — heat, moisture, and vibration can damage edges and handles. Always hand wash and dry immediately.
