If you wanna shell out the big bucks for a Bubba knife they're nice.
However, if you just want a good fillet knife the old Rapala fillet knife is a great knife.There are several other brands that work well that you don't have to spend a bundle on. I also have a white handled Shakespeare fillet knife that I really like.
Look up Smoky Mountain Knife Works catalog and look up fillet knives. They have dozens at good prices.

In 2000 I was at the Wichita Falls Texas boating expo downtown at the event center with my then fiance Mom Dad and brother's, they had carnival rides and games in the parking lot. My wife and I were walking to the door to get tickets when this lady in a booth yelled come try your luck at the Dime Toss for this $1,000 Crystal punch bowl set, now I'm not really into that kind of stuff but my mom my lady friend with me certainly would, so I pluck out 10 dimes out of my pocket tossed three dimes toward the goal which was a shot glass in the center of the bottom of the punch bowl sitting on top of a board with all the other Crystal cups glasses shot glasses and goblets surrounding the punch bowl when I toss the three dime over into the punch bowl one hit the target. The lady look dumbfounded not expecting somebody to win the prize so soon, the lady inside the booth started looking for reasons to disqualify me but luckily the city manager wasn't too far from the booth and she said absolutely not he won it, give him his prize! That thing come in handy for 25 years of Christmas parties punch and eggnog.
