Tapered GrizzlyStiks are for compound bows, longbows, and recurve bows. They're an incredibly strong, heavy, hunting arrow shaft.
They were developed do one thing very well...
to drive broadheads completely through big game animals for quick, humane kills.
The incredible momentum that can be delivered by a heavy hunting arrow is proven and simple (Heavy English war arrows made the armored French knight obsolete) but the design of tapered GrizzlyStiks is state of the art.
GrizzlyStiks are designed to drive broadheads THROUGH bone.
Continuous Taper Technology
Slow motion photography proves that when an arrow is shot out of a bow, it bends and flexes. (Called the archer's paradox) The sudden acceleration causes this bending. Draw weight, shaft, and point weight also play an important part in this bending and recovery process. The quicker an arrow can straighten out from this paradox the less drag it has and the greater the retention of forward momentum. The very momentum responsible for penetration.
The GrizzlyStik, because of its continuous taper design, has less weight on the rear portion of the arrow enabling it to quickly straighten out from this bending. (More energy retention)
However, very little thought is given to what happens to an arrow when it decelerates as when striking a target. The reverse happens. Now, however, the bending takes place in animal tissue, and this bending causes friction...drag...which slows penetration.
The GrizzlyStik, because of its lighter tail weight, straightens out much more quickly when it accelerates and decelerates resulting in less drag and therefore greater penetration.
Also, the widest and strongest part of the GrizzlyStik is directly behind the point, which results in less shaft failure. When the shaft breaks, penetration stops.
In addition, if bone is hit and penetrated, the GrizzlyStik continues to get smaller, allowing the shaft to slip right past the bone. Less bone friction results in greater potential penetration. Greater penetration results in more pass-throughs, better blood trails, and more recovered game.
Wide Spine Range
Because of the continuous taper of the shaft, the GrizzlyStik has the widest spine ranges available in the carbon arrow market. Of course, this spine range is dependent on the type of bow used, (longbow, recurve or compound) the arrow length and the point weight of the arrow.
Generally, the Sitka is designed for bows in the 40-55 pound range. The Alaskan, 50-65 pound range and the Safari, 60 to 100+ pounds of draw weight.
Extreme Forward of Center (EFOC)
GrizzlyStik is the only arrow shaft with a built in EFOC, which is proven to significantly increase lethal penetration by up to 15%. Secondly, EFOC along with the continuous taper design instantly stabilizes arrow flight for improved accuracy.
The broadhead and the first third of the shaft actually helps...pulls...the arrow through the animal tissue rather than relying totally on the arrows shaft pushing the broadhead. Pulling is much more efficient. Pulling and pushing working together is unstoppable.
Critical Mass
The GrizzlyStik shaft is designed to maximize arrow momentum by allowing the bowhunter to build arrows in the 10 grains of total arrow weight per pound of bow draw weight. Simply put, the Sitka can be made into a finished arrow weighing 400 - 600 grains, the Alaskan, 500 - 700 grains and the Safari, 700 - 1000+ grains.
Multi-Directional Woven Carbon
The tapered GrizzlyStik is the only hunting arrow to use the Multi-directional Woven Carbon. Other arrow shafts manufacturers use linear carbon fiber that is wrapped in multiple layers, similar to a sheet of plywood. These ply's can delaminate and fracture on hard frontal impact. The GrizzlyStik structural design is similar is steel reinforced concrete. In other words, chances are you'll lose them before you ever break them.
Custom Shaft Inserts
GrizzlyStik tapered arrow shafts come with custom brass point inserts and push-in, tunable nocks.
