well, since you asked....
My dream Bowie would be SR-77, with approx. a 2" wide, 10" long blade, 3/8" thick, (i guess saber grind is a given, though in the "perfect world", i'd choose full convex grind), The same overall profile of the Reg TT, but with a steel guard (like the Battle-Guard) between the handle and the blade to protect the Res-C, Satin/DC finish, a variety of handle colors...
So basically just a Reg TT enlarged about 50% with a metal guard in front of the handle. That's about as perfect a knife as i can imagine...
