Make a proper Saber blade.
I would like to see a blade model with a proper saber curvature.
Straight for about the first third of the blade and then actually curved like a historical saber.
Not straight blades with a curve on the front edge like your current models.
This would require a partially bent core, but those do exist so that should not prove such a problem.
With such a blade you could easily create many different saber models and styles.
A Polish saber
A Russian Shashka
Not to mention all the fantasy saber models that are out there.
This would make me a happy and quite poor Swedish larper.

Many options to choose
Really would be fantastic if they made sabres, especially Polish and British sabres.

Elren'dar blade is pretty damn close actually. Just a little longer. Marginally more curved. Remove the "hump" on the back, no lettering and we're in business.

put this into the custom tool also please as an option on ALL pirate swords.
A russian shashka would please me to no end.
