Maybe we could get Karnak to look into the future and see if this will happen. Naw, leave him alone. I get the feeling that Spyderco probably won't be putting out anything bigger than the Manix or Chinook anytime soon. Geez, what would the price be on something 30% bigger? I just don't see that helping sales at all.
It would be cool to have such a beast, but I think that producing such a thing would be an "uncool" business decision. Although, if it wasn't made of a premium steel, and perhaps produced at the factory that makes the Tenacious.....that would certainly reduce the cost to a manageable level.
