I have a 12 inch Forschner Cimiter and for fish >8 pounds, there is no better knife IMO. The granton edge reduces suction from the flesh to the blade, and the weight and sharpness allow you to break right through rib bones and maintain a straight, even fillet cut.
OTOH, it is kind of a worthless knife for those that butterfly fillet all their fish, regardless of size. Also seems a bit big and clumsy for the surgeons in our group that like to "operate" on their fish and take it apart chunk by chunk!

I just don't see Doc liking that knife for how he chooses to hack on his fish. I could be wrong on that.
As F4B pointed out, the folding Kershaw is the "go to" knife for that application. It holds a good edge, it can be folded up for easily packing/travel and even has a little fold out blood line scooper thing. Oh, and they are cheap. I have 6 of them....and buy a couple every time I'm up at Trusty Hardware in Soldotna. On sale, they are about $10 each.
I'd let the style of how one prefer's to fillet their fish dictate what knife to use. As always, one's results may very depending on what they are doing.
I have seen that knife in action by Bucket on a 4-million pound prime rib (or whatever slab it was)! Seemed to do an awesome job on big old slabs of meeeeeet!
I could use one of those......as I love knives..especially good ones.
