See what makes the Urban Legend Archery Broadhead stand out from the crowd
Accuracy
Accuracy is a crucial aspect of broadhead design. That's why we dedicated extensive time to designing and testing the Alpha-1 to ensure its accuracy is never compromised. One key advantage of a mechanical broadhead is that the blades remain concealed within the body until impact, reducing the cross-section and, consequently, the drag. In the Alpha-1, 82% of the blade width is hidden within the body, which minimizes drag and enhances long-range performance. The slot running through the Alpha-1's body allows for maximum blade concealment while maintaining the strength needed for the toughest conditions.
Reliability
Second only to accuracy is reliability. If the blades fail to expand, open prematurely, or the design isn't robust enough, even a good shot could end disastrously. While there are several designs on the market, we believe our style is the most fail-safe and will always open reliably. Additionally, we wanted to avoid the need for extra components, such as rubber bands, to ensure the blades stay closed until impact. By positioning a spring washer between the blades, we provide ample friction to prevent premature opening, thus eliminating the need for a rubber band.
Blade Retention System:
The red dot shows the center of mass of the blade highlighted in blue. The blade is designed so when it is shot, it will rotate inwards (closed) rather than wanting to open. This in combination with friction disk, eliminates the need for rubber bands.
Versatility
We aimed to develop the most versatile broadhead on the market, one that can be used in any situation and adjusted in real time. The expansion can be adjusted by over an inch, and the shape of the blade acts to control penetration. In the maximum position, the blades have a flat surface that will increase drag thereby reducing penetration. This configuration is ideal for a closer, broadside shot on a doe or small buck. With a quick turn of the body, the expanded blades transform into a narrower profile with a more swept design for maximum penetration.
Engineered for Strength
Our team consists of experienced and degreed Mechanical and Materials Engineers. Each part was engineered and analyzed using Finite Element Analysis (FEA) to ensure optimized strength. Through our work, the strength of the final blade design was increased by over 400% while only adding 10% additional weight compared to initial concepts.
First Rate Materials
Materials selection is a critical decision in any design. In this application, each component has a different role to play and therefore the material properties need to be cohesive to optimize the design. There is a balance between strength, weight and toughness, especially with a broadhead which needs to be both lightweight and able to withstand a tremendous amount of force.
Tip: The tip should be hard and tough to penetrate hide or bone without deforming. We used a hardened tool steel for this which has the edge retention and toughness to maintain its form. The chiseled design cuts better and saves vital weight.
Blades: The blades need to be sharp, tough and have enough flexibility to flex around bone when needed. The 400 Series stainless used for the blades have exceptional toughness, corrosion resistance and are the ideal material for this application.
Body: Aircraft aluminum was used for the body to have a strong core that is both lightweight and corrosion resistant. 7000 series was selected due to its superior strength to weight ratio.
Rigorous Testing
The final design underwent extensive testing for accuracy, reliability, and functionality. Shooting a projectile at over 400 feet per second into a target quickly reveals any weaknesses in the design! Each identified weakness was addressed, which then exposed the next potential issue. Through this iterative process, we continued through accuracy testing with distance shots, ballistics gel testing, and destructive testing to ensure we achieved a design that we knew would perform optimally in the field.
