10YT, I have one in the works from Lamson currently
11" blade, poly handle. Trying to work out the details currently, but it may be a few months or more if you can wait that long!
Prototype with Desert Ironwood handle. End ones will have pretty much the same profile, but with a Poly molded handle in Blaze Orange to keep the cost down vs the Western style handle. AEB-L Stainless steel blade. Also doing a 9" and 7", too.
In the mean time, I use a large Mioroshi Deba (240mm) on the big fish if I don't have the fillet knife prototypes on me for big fish. Only got Offshore once this year though
