In that case, the manufacturer has gotten too aggressive with the filework. Jimping is also common on skinners, capers, and other blades that require a bit more control and dexterity.

The correct tools for scaling a fish are a teaspoon, a butter knife, or a garden hose with a pressure nozzle on it.
