Vibro-Blade

A Vibro-Blade is a unique sword used by Jason Black and his family members before him. The Vibro-Blade was exclusive to the Black family.

Tactical Analysis
The Vibro-Blade is a blade that gives off a unique vibration (hence the name) which may decrease its use against average soldiers, but it cuts right through personal energy shields, making Sangheili and Spartans vulnerable to the wielder.
