Viper Asymmetrical AR500 Blade
FingerTech 3.5in AR500 Asymmetrical Blade
The FingerTech 3.5in AR500 asymmetrical blade is a single-tooth vertical spinner weapon designed for bigger hits and durable performance. The counterweighted shape spins smoothly like a standard bar, but concentrates contact into one tooth for extra “bite.” Use it as a single blade or stack two or more for a wider bite. Includes a 4-hole screw pattern for mounting to common hubs or custom weapon mounts.
- AR500 steel: Abrasion-resistant weapon material – the same amterial used in Battlebots weapons
- Single-tooth bite: Big hits instead of small chips

AR500 Bite For Custom Spinners
This FingerTech AR500 asymmetrical blade is built for custom vertical and horizontal spinners that want reliable spin-up and huge impact “bite.” The wide counterweight on the short end keeps the weapon balanced and smooth, while the single tooth concentrates contact—so when you connect, the opponent is closer to the centerline and the hit can be much more dramatic than a multi-tooth bar.
Use it as a single blade for a clean hit profile, or stack two or more for a wider bite and more contact surface. The integrated 4-hole pattern supports common hub mounting options, including the FingerTech blade mount and many custom hubs.
Safety
Spinning weapons are dangerous. Never power up outside a safety enclosure, always use a safety lock, and follow proper activation procedures.

FAQ
What kind of spinner is this blade for?
This asymmetrical blade is intended for custom spinners that want a single-tooth “bite” and smooth balance. This style blade is used in Fingertech's Viper Tail Spinner as a horizontal spinner.
Can I stack multiple blades?
Yes. You can run it as a single blade or stack two or more to create a wider bite surface, as long as your hub and fasteners are designed for the added thickness and load.
What screws do I need, and what tools should I use?
The mounting pattern is designed around 6-32 screws (not included). Use the screw length required for your hub stackup, and use the matching driver for your chosen fastener style (for example, hex/socket, Torx, or Phillips).
Does this fit the Viper Vertical Spinner Add-On?
No. FingerTech notes this is not a direct upgrade for the Viper Vertical Spinner Add-On.
What safety steps should I follow?
Never power up a spinner outside a safety enclosure. Always use a safety lock, keep spectators clear, and follow a consistent activation procedure every time.
