Where could I commission custom sparring-safe butterfly swords?

**I'm poking around at the idea of ordering butterfly swords, and I'd like to find some that are explicitly safe for sparring; can anyone suggest a smith I could reach out to?**

Specifically I'd like to be able to spar with these swords against my friend who practice HEMA. If anyone has an idea on where I could go to pursue this further, or has any insight on the feasibility of this project or even the kind of price range I might be looking at, I'd appreciate any guidance or insight!
