Firenock SwingBlade Series

SwingBlade is a mechanical broadhead that utilizes a deployment system never before seen. As its name implies, the three blades on a SwingBlade deploy by swinging out from their clasped position upon impact. This design allows it to be used on high-speed archery projectiles (550 fps) with accuracy due to a minimum crosswind signature during the flight (3/4" for Falcon & Raptor blades.) Further, designed as a completely interchangeable series, the head, blades, and bodies can be field swapped.

The SwingBlade standard head is made of stainless steel. It has a sharp edge pyramid design. The three channels of the head are designed to allow the screws that unite the head with the body to be flush with the base of the head for structural integrity. These channels additionally lower the surface contact, acting instead as air ram chambers and blood flow channels during its cutting phase.

SwingBlades utilize the single bevel front and back design. Blades are 0.5 mm thick surgical grade stainless steel hardened to no less than 52 HRC.

All three bodies, like all Firenock broadheads and field points, are equipped with FACT 2.0, our Double O-ring system that helps self-concentricity. The Falcon blade provided the better angle of cutting while the Raptor blade will comply with the laws of the state that has no barbing rules as it has an 89 degree back cut. The latest Talon blade is designed for those who are not shooting over 315fps and prefer a larger cutting diameter than SwingBlade Falcon, and Raptor can provide (Talon is just over 1 2/3" cut while it is 3/16" cut on Falcon and Raptor).

To satisfy the need for the lower poundage and large cutting diameter of the heavy FOC thin diameter arrow, for falls of 2019, Firenock offers the Saber blade set. Just like all Swingbalde set, it is interchangeable, and this blade is designed to fly true with Aerovane III at up to 300 fps. It, however, has the largest close and open blade diameters. Saber's17-degree blade angle shall maximize penetration with the least amount of force and energy lost. When fully open, it is 1 13/16"/ 46mm.

Deployment Method 

SwingBlade’s blades will only deploy when there has been a change in density—the only thing actually keeping the blades from swinging open is one rubber O-ring!  After contact with something of a different density than air, such as flesh, the blades will open via their hinges which are directly perpendicular to the impact surface. This process of opening overrides the O-ring that originally held the blades tucked.  The hinge pin screws, although extremely tiny in diameter (0.175mm), are critical in this application, which is why we choose to make them from HRC60 CRMO steel. These pins also allow one to easily replace or switch out blades.

    Super excited to try this out hunting deer. Everything I have read shows this with aerobolt and aerovane 3 will be a devastating combination. Hope to post more after using in the field. Great design and quality of products.
