Scaling a fish can be done easy enough with a knife, but a fish scaler is made to make quick work of the task. The tool has a grated surface which when ran down the skin of a fish, pull up the scales pretty quickly.
Most models have a single row or double rows of serrated blades (that may be curved), but some have an additional blade that points outward to gut the fish after scaling.
