For 2021, Rage has solved the “collar” issue on its famed Trypan. A two-inch cut killer, the Trypan is fitted with .039-inch blades that are both sharp and durable, and the super swept-back blade angle boosts penetration. Putting icing on the cake is No Collar technology. Now Trypan lovers can go without the grey Trypan specific collar and remain confident their blades will remain closed in flight.
