It Starts With Speed, It Ends In Destruction Backdraft by Deadly Kinetics is a fail-safe fixed blade broadhead wrapped in a patent-pending thermal deforming cartridge designed to do one thing exceptionally well:transfer kinetic energy where it matters most — inside the target, with or without the petals intact. That's right, when the substrate is thinner, the petals may tear off cutting their very own wound channel for the ultimate possible damage Skipping an arrow down the trail is wasted energy. With modern bows the KE is unmatched from just a few years ago. We harnessed it. It will destroy whatever it comes in contact with. When impact occurs, the cartridge thermally deforms under force, converting blistering speed into destructive trauma instead of letting energy escape out the other side. The result is violent energy transfer you can see — and trust. If you understand hollow point bullets and their energy transfer, you understand this. Want to be sure? We send 5 complete ready to hunt broadheads with 5 additional cartridges so you can see for yourself. Go blow something up. Seeing is believing.
