Grizz Tricks are manufactured from 100% steel. The most common reaction to the Grizz Trick is a smile and a comment of "wicked". With a 1-1/4" 4 blade cut it was made to blow a comparable hole to a 1-1/2" 3 blade mech while having superior strength and penetration, and can't fail reliability. Grizz Tricks use the fail proof patented Alcatraz BladeLock, premium Lutz Solingen Germany .035" blades and a super stron Rhinosteel Ferrule to match the unbeatable design with the finest quality parts. Like its namesake, the Grizz has awesome performance taking down animals. Available in 100 and 125 grains. 3 per pack.
