Compressor Viper Shank: OAL: 7.5” / Blade: 2.8” Why Choose Xtra-Flex? The TAK Compressor Viper Xtra-Flex was engineered for practitioners who want to train harder, longer, and more realistically while reducing the risk of unnecessary injury. Built from the same high-density rubber foam as the standard TAK Compressor series, the Xtra-Flex incorporates additional compression slots along the leading edge. These engineered compression zones allow the blade to flex and compress under impact, helping absorb energy during thrusts and strikes while maintaining excellent durability and realistic handling. The result is a trainer that encourages full-speed, full-contact combatives with a higher margin of safety. Recommended For Beginning practitioners learning realistic combatives Bringing new students up to speed with less pain and fewer training injuries Advanced practitioners conducting full-contact fight training Striking, clinch work, and grappling where realistic contact is desired Instructors who want increased safety without sacrificing realism Not Recommended For The Xtra-Flex series is designed to absorb impact against the human body—not rigid surfaces. Do not use for: Striking hard armor or protective helmets (except approved eye protection and neck guards) Heavy bag or hard training dummy work Repeated impact against rigid training knives or other hard objects Any application that forces the blade beyond its intended compression range Repeated impact against rigid surfaces can over-compress the engineered flex zones and shorten the service life of the trainer.
