![]() Others, like a Grim Reaper or a Spitfire, use no o-ring and have an internal locking device to keep blades from deploying prematurely. Some, like the Sidewinder or Jackhammer, have their blades held in place by a rubber O-Ring. The Rage broadhead is the one that really set the world on fire about 10-12 years ago with their rear-deploying slip cam design, which took very little kinetic energy to deploy as opposed to over the top heads like a Rocket Sidewinder or a Spitfire. As they evolved, blades got thicker, cutting diameter got wider, blades were added, etc. screw one on and go hunting, no broadhead tuning required. The main advantage at the time of creation was the field point like accuracy and sidestepping any potential tuning issues, they were (and still are) basically a plug and play design. There were early prototypes of mechanicals from way back in the 50's or 60's but they really didn't come into play until the 90s.the NAP spitfire is the one that was most people's introduction to mechanicals. A Slick Trick is a good example of a modular 4 blade style head with a chisel tip, and a G5 Montec is a good example of a 1 piece 3 blade cut on contact ( where the cutting surface runs the full length of the blade) When compounds came along, you also saw the advent of more modular style heads like the Muzzy and NAP Thunderheads that featured Trocar/Chisel tips for encounters with bone, changes in blade angles and shortening of the broadheads. Somewhere along the way they invented 3 and 4 blade heads to increase the cutting surface to increase hemorrhaging (bleeding) as the broadhead passed thru the animal, but like most everything in life, there is a trade off, and that tradeoff is reduced penetration compared to two blades. The experts claim that a single bevel has some rotational twist when it hits a target and is better for splitting bone than a double bevel when encountering shoulder blades, heavy ribs, etc. These broadheads were originally designed for Traditonal archery which shot a fairly heavy arrow at what is now considered a slow speed, using momentum to drive the broadhead thru the target animal. Double Bevel are more common and examples of those are Magnus Stinger, Zwicky, Bear Razorheads, etc. Examples of Single Bevels are Kudu Points, Simmons Landsharks, Tuff Heads, Rocky Mountain Cuththroat, etc. There are two types of Two blades, Single and Double Bevel, meaning the single is sharpened on one side of the blade and the double is sharpened on both sides of the blade. You have three types of Broadheads Fixed, Mechanical and Hybrids, with Fixed and Mechanicals being the most common so we will stick with those.įixed blades are the original broadheads and the two blade was the original design. I'll take it a step further for every newbie asking about a broadheads for archery equipment (Disclaimer, these are my opinions based on experience, but I would say it holds true for all forms of archery) Yes, accuracy issues with fixed blade at xbow speeds is what Ive been told. I was not impressed with the Trypan whatsoever The rage Hypodermic is a good broadhead but for archery I personally recommend a 3 or 4 blade head vs. I may start a separate thread on fixed vs expandable for xbow.Īt crossbow speeds you can get planing issues with fixed blades, especially at distance. They have worked fine but I have a small sample size. I use Rage Hypodermic because the bow shop recommended. ![]() For that reason I assumed I would want fixed blade but I kept getting told with a crossbow to go with expandable. I like to keep things simple and certainly as few moving parts as possible. Ive only hunted with a crossbow and only a couple years. ![]() Im an experienced hunter but new to bow hunting. ![]()
