Boner Broadheads

The what and how and what sets us apart...


Why? Well…because we are frustrated and concerned by the ineffectiveness of many of the broadhead and arrow combinations being shot by bowhunters at living, breathing animals.

There are too many companies today hocking gimmicky junk to well-meaning bowhunters. They have been talking to us for the past few decades about Kinetic Energy, speed and shooting one pin to 60, marketing products designed to whack ‘em and stack ‘em, open big holes, fly like field points, rage against nature, and a bunch of other nonsense.

The problems with these products arise when the broadhead meats the bone!

We as bowhunters owe it to the animals we hunt to shoot a set-up that maximizes momentum and penetration on sub-optimal hits – like a front shoulder or rib. If you’ve been doing this long enough you know that sh!t happens – animals jump strings, nerves get ya, arrow deflects off a branch you didn’t see. When your broadhead hits bone, you have to know it’s going to have enough oomph to break solid bone and poke a hole through both lungs.

Our mission was to produce heads that tune easily, whether out of the best engineered compounds or your stickbow, and “Break Through” bone.


How They Work...


  • Single bevel blade that when matched with the correct fletching creates rotation through the air and through the animal
  • Narrow to minimize planing and drag through tissue and bone
  • Heavy and solid to increase your arrow’s FOC and maximize penetration on bone hits
  • More weight toward the tip than your typical triangular designs, to minimize bending on bone hits
  • No venting to minimize drag created by vents hanging up on tissue or bone, and eliminate inconsistent flight and noise created by wind moving through vents
  • Longer ferrule on the 225 grain head to increase stability throughout the length of the head
  • Teflon coated to minimize drag and increase penetration

Single Bevel Rotation

A single bevel head rotates in flight due to the uneven force being applied to the blade as it flies through the air. In order to achieve proper rotation, the head bevel must be matched with the correct fletching.

If you’re shooting a compound: a right bevel head needs to be matched with a right helical or right offset fletch, and vice versa with left bevel. If you’re shooting a stickbow: a right bevel head needs to be matched with right wing feathers and fletched in a right helical jig, and vice versa with left bevel.

The head rotation creates a lever when the blade hits bone, opening up a big hole for the rest of the arrow to pass through with minimal drag. Compare this to a mechanical head, or chisel tipped three-blade design. Those designs simply don’t penetrate bone as well. They are not efficient designs. See some video evidence here.

The in-flight rotation also creates increased consistency. Think of rifling in a barrel as an example – spinning the projectile keeps it on a tighter path.

Benefits of a narrow head

  • Narrow head = less drag = better penetration
  • Narrow head = less planning = optimal arrow flight = better penetration
  • Narrow head = easier tuning = optimal arrow flight = better penetration

I often hear guys complain about the difficulty of trying to tune fixed blades out of a compound, well it ain’t that hard…if you have a properly tuned set-up. I don’t like saying “properly tuned bow”, because really you have to tune your arrow to fly correctly out of your bow. You can change things on your bow to accomplish this but ultimately it’s arrow flight we’re concerned with. If you can shoot field point tipped bare shaft bullet holes down range, then you can tune those arrows with the correct fletching to shoot our broadheads. Check out some video here.

Heavy, Solid Heads

A heavy head ensures that more of your total arrow weight will be front of center. High FOC arrows are more accurate because they are less susceptible to being pushed off course by wind or other factors. High FOC arrows also penetrate better because the mass is up front, acting like a hammer, while the tail of the arrow is only there to help steer. Here’s a great illustration to show what we mean:

Straw vs. Pencil vs. Dart illustration

Our blades have more weight toward the tip

Your standard triangular designs are more prone to bending on bone hits, which impedes penetration.

No Venting

Anything on a broadhead or arrow that might hang up on tissue or bone is going to negatively impact penetration. Venting, especially on broadheads shot out of high speed bows, make noise and noise is bad. Venting can also create inconsistency in arrow flight, especially at longer distances.

Longer Ferrule on the 225-grain head

Running the ferrule further up the length of the blade provides additional stability and strength on bone hits.

Teflon Coated

Less drag = better penetration…and the white Teflon looks cool with the red ferrule.

The bone breaking magic

only happens though when you have the right broadhead AND bow/arrow combination.

What we mean by this is a bunch of scientific stuff that we are about to explain below...

Some Applied Physics

In order to get an accurate representation of an arrow’s ability to penetrate bone, you have to take into account total arrow weight, % of arrow weight that is front of center, efficiency of broadhead design, bow and arrow tune, etc., as these things enable us to better quantify how much drag our arrow will have on a bone hit. Less drag = better penetration.

Maximum Penetration =

  • Adequately weighted arrow +
  • High Front of Center +
  • Efficient Broadhead+
  • Properly Tuned Bow and Arrow

Importance of an adequately weighted arrow

Momentum = Mass x Velocity (at impact)

Momentum in the example of bows and arrows measures your arrows ability to penetrate at point of IMPACT. It does not account for resistance factors such as drag, broadhead efficiency, etc. but does give us a great baseline to compare arrow weight combos with all other variables being consistent.

Two arrows shot from the same bow:

Arrow #1: 350 grain arrow x 320 fps at point of impact = 112,000

Arrow #2: 500 grain arrow x 270 fps at point of impact = 135,000

Arrow #2 has 20.5% greater momentum at point of impact!

If you play around with the numbers you’ll see that an arrow’s mass has a greater impact on momentum than the velocity. A heavier object is also more resistant to being moved off course.

Kinetic Energy = 1/2mv^2

This measurement is incorrectly applied to hunting projectiles in that it overemphasizes the effect of velocity and measures it at the point in time when the projectile leaves the weapon. In both archery and firearms, it is irrelevant how fast your projectile is going when it leaves. What we care about is how fast it’s going when it get’s to the bone.

The kinetic energy calculation is worthless when talking about ballistics as they pertain to killing animals.

Importance of High FOC

High FOC arrows are more accurate because they are less susceptible to being pushed off course by wind. High FOC arrows also penetrate better because the mass is up front, acting like a hammer, while the tail of the arrow is only there to help steer. See illustration above for a simple way to think about FOC.

Importance of an efficient broadhead

A bowhunter shooting a brand new 70 lb draw weight compound might build an arrow with high front of center and adequate total arrow weight, and tune it to his bow perfectly. He’s in a baseball at 100 yards. Then he screws on a mechanical head that “flies like a field point”. That’s not an optimal set up for a bone hit at any distance. Period. End of discussion. It’s just not. This is a fact that is not debatable …regardless of how many more podcasts get recorded on the subject.

Importance of a properly tuned bow and arrow

If you try and throw a light fixed blade head on a soda straw weight arrow you are 100% going to have problems tuning your bow. The problem is the light arrow and light broadhead NOT necessarily the broadhead design.

Think back to the illustration of the straw vs. pencil vs. dart.

Before you screw broadheads onto your hunting arrows you should be shooting bullet holes through paper out to your maximum effective range.

Sometimes I actually leave my arrows just a touch weak because I know that putting fletching on one end and a broadhead on the other is going to a result in a dynamically stiffer spine. This is a probably a good opportunity to talk about static vs. dynamic spine as well.

Static Spine

Static spine is what’s measured at the factory. It’s measured by calculating how an arrow reacts when an 880 gram or 1.94 lb weight is suspended from the center of a 29” arrow, supported by two points, 28” apart. How far the arrow bends (measured in inches) is multiplied by 1000. So, a 300 shaft arrow bends .3” when the weight is applied as described.

Dynamic Spine

Dynamic spine measures the real world behavior of the arrow when force is applied to it by your bow. It accounts for arrow length, weight applied to either end of the arrow, nock fit, center shot vs. non center shot, etc. Any change you make to your arrow or bow will affect the dynamic spine of your arrow.

Some basics on dynamic spine

  • Adding point weight weakens the arrow. Your arrow will have more whip or bend in it with a heavier point on the end.
  • Removing point weight stiffens the arrow. Your arrow will have less whip or bend in it with a lighter point on the end.
  • Lengthening the arrow weakens the arrow. Point weights being equal, a longer arrow will have more bend or whip than a shorter arrow.
  • Shortening the arrow stiffens the arrow. Point weights being equal, a shorter arrow will have less bend or whip than a longer arrow.
  • Anything that creates drag will stiffen the arrow: If you take off your field point and screw on a broadhead, your arrow will act stiffer. Same with adding fletching, etc.
  • Adding a heavier nock (lighted) will weaken your arrow, as you a are adding weight to the end.
  • More bow weight (applied force to arrow) will make your arrow act weaker.
  • Less bow weight will make your arrow act stiffer.

Bare shaft Tuning

Start with a full length bare shaft (no feathers or fletching) and a field point of the same weight as the broadhead you will be shooting. Shoot an arrow at 30 yards and note what the nock end is doing.

  • Nock left = too weak
  • Nock right = too stiff
  • Nock high = nock point too high or end of arrow is bouncing off rest or shelf
  • Nock low = rest is set too high or nock is set too low
So applying the dynamic spine basics above…

If you want to make your arrow act stiffer, cut it shorter or increase your bow weight.

If you want to make your arrow act weaker, shoot a longer arrow, add more point weight or lessen your bow weight.

You can also play around with feather or fletching configuration, nock weight, nock fit, etc. to dial in your arrow flight.

When the arrow is flying straight (as an arrow) you’re good to go!

Once I get my arrow bare shaft tuned I fletch it and shoot it again to make sure it’s still going flying correctly. Then I paper tune it to make sure there are no flight imperfections that I’m not picking up with my naked eye.

Last, I broadhead tune. I start at close range and keep shooting until I get to my max effective range.

If you bare shaft and paper tuned correctly, your broadheads should group with your field points out to your max range, but at longer ranges they may group a little below because of the increased drag created by putting a broadhead on the business end.

If the broadhead shots pattern (I say pattern because I only shoot one at a time and chart where they hit – otherwise you’ll be ruining arrows!) together but to the right of where your field points group, your dynamic arrow spine was likely too weak to begin with. Cut a ¼” off your arrow and try again. You could also dial your bow’s weight back a few pounds. If you’re shooting a stickbow, you can raise your brace height a touch, which will create a shorter power stroke resulting in less applied force to the arrow.

If your broadhead shots group together but to the left of where your field points group, your dynamic arrow spine is too stiff. You’ll need to shoot a slightly longer shaft, heavier point weight or crank your bow’s poundage up a few. If you’re shooting a stickbow, you can lower your brace height a touch (assuming it doesn’t create string slap to your bow arm), which will create a longer power stroke resulting in more applied force to the arrow.
