To produce the toughest and most durable products available, we are using high impact polycarbonate plastic which we are machining by hand to exacting standards. This high grade material is the same stuff used to manufacture bullet proof glass and high impact lenses. Its specific gravity is similar to the mulga wood once used in the heart of Australia for throwstick making, but it is much more durable than hardwood. Unlike desert mulga wood, which may possibly warp with age, the polycarbonate holds its tune forever unless forcibly warped under considerable force.

But to answer your question more specifically, the below novel, cringe worthy and extremely boring video was recorded in one take. It features the destruction of a granite boulder by the use of a polycarbonate throwstick. The boulder aside, no throwsticks were apparently harmed in the production of this video, although the thrower got very tired....

Spoiler alert: After more throws than we want to go back and count, the stick didn't ever break.... If you have the patience to do the count for us, please leave the number in the comments section below the video on youtube.

How tough are polycarbonate throwsticks? After making and selling many hundreds of them internationally since 2017, with many subject to significant abuse, only a few have been reported broken in that time. Every piece of polycarbonate is unique. We've had reports of a few sticks breaking when coming into sharp contact with hardwood trees. We believe this is because the edge is captured in the bark in these instances and stopped abruptly at whatever the sweet spot is that over stresses the material for a given mass distribution. Polycarbonate likes to wiggle its way out of trouble. Also, sub freezing temperatures can make polycarbonate more fragile than otherwise and make breaks more common when throwing in that weather.

Although the stick in this video didn't shatter, we have been able to shatter one particular stick in other tests in as few as 11 throws in extreme conditions. These tests were conducted as hard as we could throw against large boulders, at point blank range.

In any case the durability results are extremely impressive. The bottom line is that polycarbonate throwsticks are very durable. In spite of this they can possibly break and we don't warrant that they won't or encourage our customers to abuse them so that they would. Don't try this at home. Be safe, sane, and respectful of your throwstick. Throw at softer targets. But whatever you do, have fun!! With a product this durable, it's meant to be thrown!
