The gladius, the weapon that made the Roman Empire. It was a steel, double-edged thrusting sword designed to kill quickly with minimal effort.
The pila, a type of javelin. Every Roman legionary carried two pila into combat. The pila had a special tip that broke as soon as it made contact with a hard surface; this prevented the enemy from picking it up and using it against the same guy that threw it.
The scutum, or "tower shield". It was made primarily of wood with a reinforced bronze edge. The scutum was designed to give the bearer optimal protection, and could be used to form the famous testudo formation, where mutiple legionaries would overlap their shields to create a protective wall.
I don't quite well remember Urumi used with prominence, at least not in the commonly available documentation of major wards or at museums etc.
Probably because it had only limited and very specific scope of application.
Traditional khanda was a bit wider towards the tip because it had to be used on both sides & make contact with adversary's body as soon as possible.
Khanda was the weapon of desperation visible in final stages of battle.
It could be used to butcher an awed enemy and finish the story. Also when a Rajput warrior would see that victory was not near, he would wave the Khanda blaze-fully to cause maximum damage before laying down his life.
Every people have a distinct way of looking at wars. Among many examples, Rajput desperado can be summarized also perhaps by these lines from - The Bhausahebanchi bakhar which quotes Jayappa Shinde's correspondence back home during his campaign in Rajasthan:
"These are Marwadi Rajputs, incredibly valorous; their bodies dance around even if they are beheaded"
Actually we dont have any reliable articles on Ancient Indian Weapons over Internet!!
Dunno about the Rajputs but it seems Kingdoms of Kerala used Urimi a lot. Urumi can be used has secondary weapon, They are light weight can be used used has belt across the warrior belly.
In Battlefield, Kings and Officers are said to be carrying Urmi with them always.
