Nothing confirmed that I could find, but presumably it's some type of arm mounted blade, that comes out either with a spring on it, or using a lock unlock system with momentum as the method Zed uses to shoot them out. Or he just uses shadow power, that's possible.

The only thing that wouldn't really work is that the swords physically would be unable to retract with how the gauntlets are designed, but maybe he just stores them in a shadow dimension or something.

Most likely, it just looked cool and so it became his weapon. If you want to find something simirlar look up arm mounted blade, but it looks like it's somewhat inspired by a Katar if you want a weapon actually used seriously in history.
