I have the Cutco and the Dexter wood handle with carbon steel blade as well as an old Herter's Canadian filet and a very old Western. My wife likes the Cutco best. She does the fish cleaning at our house. However, we do not cut through bones with a filet knife. I use the Western because I like the way the handle fits. They probably quit making them 50 years ago.
A fishing buddy down on Chesapeake Bay cleans fish like you do, by cutting through the rib bones. He uses a discontinued Browning knife that is serrated and thick bladed just above the handle and then tapers to a thin flexible blade toward the tip. He says it is the only knife that works for his manner of fish cleaning. Of course, that knife was discontinued 10 years ago. Ted Trueblood said that if you find something you really like, buy two of them because if it is any good they will quit making it.
