An urumi (Malayalam: uṟumi; Sinhalese: ethunu kaduwa; Hindi: āra) is a sword with a flexible, whip-like blade, originating in modern-day Kerala in the Indian subcontinent. It is thought to have existed from as early as the Sangam period. [~600BC-300AD]
The urumi is handled like a flail but requires less strength since the blade combined with centrifugal force is sufficient to inflict injury. As with other "soft" weapons, urumi wielders learn to follow and control the momentum of the blade with each swing, thus techniques include spins and agile manoeuvres.
These long-reaching spins make the weapon particularly well suited to fighting against multiple opponents. When not in use, the urumi is worn coiled around the waist like a belt, with the handle at the wearer's side like a conventional sword.
I mean, if a military were to have the financial means to offer a cannon to every soldier, they would. Economics are the backend of every war. In 600 BC, a flexible sword would be both far more expensive and less effective than a spear, which is the crux of my question. I only read the wiki after my comment so I take back halberds. 7355608 proposed an interesting use case in a casual carry belt that feels reasonable.
“Thaddiffer, I do say, what are those Frenchmen doing across the hill?”
“My dear Billiam, I believe they’re attempting to flank us. Shall we preemptively prepare a ceaseless 500 grape shot barrage to render them, the landscape, and everything else within a quarter mile into an unidentifiable vapor?”
“No, no, we shan’t be rude, we simply must offer them first volley. Anyone for tea in the meantime?”
*raucous agreement*
(Yes, I know what you’re referencing but this is magic “everyone gets a cannon” canon)
When slashed around, creates a very dangerous bubble around the user that can keep multiple enemies at bay
Can be several meters long, giving it more reach than most polearms
Effective against shields since the end can wrap around the shield to hit the enemy
Look badass
It's not meant to be a mass produced weapon that gets distributed to everyone in the militia. Spears are far and away a better choice for that. It takes years and years of training before a fighter should even consider learning how to use one. But in the hands of an elite warrior they can be incredibly deadly.
