On the other side, the face of the blade has an angle down just before the edge; this is known as a bevel. So you have to use a sharpening tool for the beveled edge.

Place the rod in one of the serrated scallops.

Choose the angle that is easy for a serrated blade because you can use the angle of the bevel, usually between 13 and 17 degrees, compared to the edge of the blade, which is shallower than used for sharpening knives.

  • The bevels are mostly ground to the same angle, about 20 to 25 degrees, if the knife has a straight edge portion.

If the rod is tapered, then locate the rod in the gullet at a point where the diameter of the rod is the same size as the gullet or a little bit smaller.

Sharpen the gullet

Check the burr

Continue sharpening
