I like these a lot. What are the abilities of the painter ninja? The fella on the top left with the 'cypher' nightstick swords; Wouldn't they work better if the edge of the blades faced away from the perpendicular handles? That way you could hold them with the extra handleswithout fear of cutting yourself.
Part of the problem with bladed Tonfa is that part of the more common styles for regular tonfa have the long end being used for an "inside cut" meaning the side that would normally be against the arm is brought back across the opponent if the blades were reversed then the attack would be like hitting them with Kenshin's reverse blade sword. though "back hand" attacks with this form would have the same problem best way to go would be a European short sword style so both sides cut though it would remove all chances of using the tonfa defensibly which was there original design.
