The Katana is built with the finesse thrower in mind. Recommended downwind driver. Hit the angle right and watch it bolt out of sight. The physical characteristics resemble a Boss with the flight characteristics of a Sidewinder on steroids. Master the technique of Katana and rule the course. Blizzard technology incorporates thousands of microbubbles into our durable Champion plastic. This results in high speed, premium plastic drivers in weights all the way down to 130 grams! Testing indicates that models under 140 grams are light enough to float in water!
