For hunters who rely on dead accurate arrow flight and fail safe rearward blade deployment, the Tekan broadhead provides everything you'll need. Requiring less than three pounds of energy to open, a rock solid one-piece stainless steel ferrule, and a fatal 1-1/2" cutting diameter, this newly designed mechanical broadhead offers complete pass-through and produces massive entrance and exit wounds. Improved O-ring retention system for enhanced performance. Black finish reduces glare. Made of 100% steel with a cut-on contact design and diamond cut sharpness. 100 grains.
