I disagree, the sword is massive enough and it looks like it has two separate blades folded up, those could easily fold outwards and form a Scythe. In addition, since when did we see anything about it lacking a ranged form, it probably still has one. Just because we've only seen the sword form so far does not mean it doesn't have two other forms. It probably is a sword-sniper-scythe. 

Plus I'd argue sword and nunchucks are just as different as sword and scythe. The only similarity those two have are being blunt weapons, while sword and scythe are both bladed weapons.

Given that most of this is opinion based and there is evidence to suggest both I'm not going to argue furthur.

Just curious though who did they have that had a sword/nunchuck weapon?
