University Study - Arrow Vane Designs for Improved Broadhead Flight

Thank you. We invested thousands of engineering hours in this two year study. I wanted a better scientific understanding of arrow flight with broadheads on the front, which has been lacking in the industry, so that I could become a better bowhunter myself and have the data to advise our...

University Study - Arrow Vane Designs for Improved Broadhead Flight

All the modeling and empirical testing was done with Iron Will broadheads vs field points, but the findings would apply to any fixed blade head and even some mechanicals where the geometry creates a significant lift when at a slight angle to the airflow.

Iron Will Broadhead Singles Available & Free Shipping

From our fluid dynamic modeling, our single bevel heads create a small amount of rotational torque, but it is very small compared to vanes at 2-3 degrees. We have had a couple customers swear they make their arrows fly better. In my experience, flight is similar with single bevel and double...

Yes, you can call our tech support at 970-236-4884. Generally, if you are properly spined, the bow is relatively well tuned, and you have enough vane on the back, they should fly well for you. Our tech support can help you figure this out.

For Those Of You Who've Been To Total Archery Challenge (TAC)

If you haven't shot a TAC before and haven't practiced a lot at long distance, bringing a bunch of very low cost arrows is not a bad option. You will likely loose some and put some into boulders on the harder courses. Another approach is to put more money into the arrows and strengthen them up...

Iron Will Vane - Personal Feedback

I appreciate any feedback, even when it's critical. It gives me a chance to explain and sometimes rethink. I never said the IW Hybrid Hunter vane was the quietest. It was about average in the CU testing. The max stealth is a little quieter. I did say that we found the hybrid material to be...

Iron Will insert with Slick Trick? Insert depth?

HIT inserts get pushed .458 inches into the arrow. This allows for variation in the shank and thread length of various field points and broadheads per the industry specification. It is normal to have a small gap between the HIT insert and the shank of the broadhead and this is actually needed...
