It might help to declare what extreme uses you plan for it. Subhilt fighters are generally considered self defense "fighting" knives with limited utility applications. The subhilt itself is copied from a much older design, Loveless I believe, and was a custom. It pops up marketed toward younger buyers who like the looks but don't know the utility is compromised by the actual subhilt itself, the blade grind, and other factors that aren't found on designs for actual hard use knives.
