I want a handle a long butaniku

and see how it feels in hand.
I am 5' 6" and the short butaniku feels too short to me by an inch or two.
The AK is a good short sword.
The TNT is great because the balance and speed are the best of all the short swords IMHO. It moves very quick and the point can be flicked around much easier.
I would love to see an INFI TNT-15.
The gladius is a beefy blade and its got ok slicing potential it has much more perceived weight and its harder to flick the tip around. Its strength is its stabbing capability its design lends itself to thrusting and its a heavier blade its the opposite of the TNT.
No experience on the Rucki, waki, chuckette or MOASH. The Moab is a monster. Its length could classify it a short sword to some. Its a super chopper, I wouldn't want to try to use it as a sword.
The F16 is much like the TNT, but not quite as nimble and light in hand, but has about the same reach.
Thats my .02
