  • This asymmetric Gr5 titanium weapon bar is ideal for vertical spinners. Use single, or stack two or more for a wider bite!
  • Includes a 4-hole screw pattern that can be used with the Blade Hub or with your own custom hub.
  • The asymmetric shape is balanced by having a wide counterweight on the short end. It spins as smooth as a regular blade, but with only a single tooth to contact the opponent, you get twice as much "bite" - the opponent will be twice as close when you hit them, which can mean a huge hit instead of a small chip!

As with anything related to combat robots, it is potentially dangerous to add a spinning weapon to a robot. Never power up the robot outside of a safety enclosure. Always use a safety lock and follow proper activation procedure.
