video How To Clean A Catfish Quickly
Cleaning catfish can be something that is challenging for some, but many go about it the wrong way. Using the correct tools and technique you can clean a catfish in less than 15 seconds. 

I prefer to use an American Angler MT3 electric fillet knife and can make pretty quick work of cleaning a fish using these tools.

I use a normal fillet knife. Had no idea electric would be like 10 times faster.
