The Praetorian dual blades
Used and seen in TLJ by Snokes guards.
These dual blades are a 1:1 screenaccurate production, they are strong and can be (dis)connected from each other. The is a aluminium bar to support the connection and its covered by two plates with strong magnets.
Its a good show / cosplay piece but not mend to use as sparring weapon. The way we printed it it can handle a a hit.
