I normally do not scale fish but rather fillet them with my electric knife. I have an elderly widow down the street that loves to eat pan fish. She has asked me several times to scale her some crappie. I told her I did not scale fish but would be glad to give her all the fillets she wanted. Well I got to feeling guilty and decided to scale her a couple of crappie. I just happen to have hanging on my shop wall a device called an EZ Scaler. I don't know how long it had been there and really thought it was just another device to make money. Well I decided to give it a try and was I surprised that it actually worked. Therefore, my Tip is if you are going to scale fish give this thing a try. It fits right into your Mister Twister fillet knife and makes short work of scaling a fish.
