I assume you are referring to the blue G-10 on the BladeForums Spyderco Native. I like it.
I would call it Royal Blue or perhaps medium blue. [Now if you want to call it bright or intense blue,
that would be OK.] It is the same Royal Blue available in thread for thread work on fishing rods. It looks very good on a black rod blank.
I just went out to the garage and compared the two. Nice match, but I'm not sure 440V would be good for a matching fillet knife. Rusts a little easily and I would not want to loose my Native.
See Lynn, a new market, Royal Blue G-10 handled fillet knives.....but what would be the ideal steel or other cutting material? I went back and added the latter because I would not want to rule out non-steel materials such as Talonite. I wonder if a relatively thin piece of Talonite would be strong, flexible and tough enough. It would not take much for a modest sized fillet style knife, but the savings would not be directly proportional as I recall thinner stock being more expensive [?????] I would certainly like to volunteer to test one.
A local custom maker makes them in 440C. He says he has one model which is more of a user, but the ones I have seen at the local show are too long and too fancy. Since they take him so long to make, they are too pricey to fit my wallet, especially for a knife used over water.
What I actually use is a 6" Wusthoff Trident boning knife. It was a little too stiff to suit me in the kitchen and better than most of the cheapies out there so it became my fishing knife. Yes, it is probably a little stiff to be the ideal filleting knife, but the stiffness actually makes it more useful for other fishing tasks.
