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. Knife Brand Bevel Characteristics Victorinox Clear, visible bevel on one side Wüsthof Pronounced bevel, easy to identify Global Subtle curve, requires good lighting Step 2: Use the Sharpening RodFollow these steps for each serration along the blade: Insert the ceramic rod into the first serration near the blade base Match the rod's angle to the bevel (typically 13–17 degrees) 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.Step 3: Remove the BurrAfter 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 when slicing.Step 4: Clean and DryRinse your knife under warm water and dry immediately with a soft cloth. Even stainless steel can corrode if left damp.Use professional cleaning accessories from our dishwashing and cleaning collection to maintain blade hygiene between uses. Key Takeaways Only sharpen the beveled side of a serrated knife — never the flat side Use a ceramic rod that matches the size of your knife's serrations Work patiently through each tooth with light, consistent pressure Remove the burr gently to avoid damaging the edge Clean and dry immediately after sharpening to prevent corrosion Caring for Your Serrated KnifeProper care extends the life and performance of your knives.
