FingerTech 3.5inch x 0.125in Asymmetric AR500 Disc

The popular 3.5in titanium blade is now available in AR500 - the same material 250lb BattleBots weapons are made from! This asymmetric AR500 weapon disc 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 our Blade Mount, 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!
