Pocketknives made of steel may require additional pulls because of its hardness compared to any other type of metal knives. For better leverage, place the sharpener on a flat and sturdy surface when sharpening.

To sharpen a serrated knife and gut hook, use the tapered rod. Extend the rod and match the grind angle to the serrations. To avoid damaging the serrations, choose the diameter of the rod that is slightly smaller than the gullet or tooth of the knife. Push the rod into the serration or hook with light downward pressure, gently rolling it as you do. Repeat on the entire serrations.

Continue pulling 4 to 5 times until the necessary sharpness is acquired. After sharpening, continue to pull the blade on the fine ceramic blades to polish the edges and set the durable sharpness.

The carbide slot is very aggressive in sharpening and can be used for really quick sharpening but is not advisable for frequent use as it could remove more metal from the knife and in time could damage its original formation. Use this slot only for severely damaged knives, making 3 to 4 strokes with moderate downward pressure.
