Gladius
I was looking for a gladius template online, but couldn't find one, so I went and made it myself. Would make a good prop for any model-making, or, if you find a printer with the space, it could make a good prop for a Roman Legionaire or gladiator costume.
This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/0ClF106GTwO
