sorry, im not gonna be much help with the knife making. im a big fan of bowie styled throwers also (and just throwing regular 15-16 inch bowies). i have the CS perfect balance and i like it alot. does everything the bigger bowies'll do without being "too big" (carrying). another cheap/fun one (but they wont last long)=any old rusty 15 inch pakistan bowies you find (>$10). i throw them until the brass guard and wood handles break off and then just keep leather wrap on handle after that. (i have a few damascus bowie blanks i leather wrapped the handle on too). i dont think ive thrown anything over 13'ish inches that didnt eventually bend (some more drastic than others). ive only ever broke 1 and it was 1 of a set of 3 from Hibben (the 12 inch hall of famers), and i think it was a defect in the metal. broke right away, just snapped clean in half, straight line. they replaced it and ive had no more problems.
