Questions & Answers

Why do concave Broadheads cut bigger holes than straight blade or convex shaped heads?

Answered by Dr Ron Sanders

  • Summary... As we begin this brief tutorial, remember that high-speed photography clearly shows that a broadhead wound is produced by the front 15% of the broadhead cutting edge and the last 10%.
  • Remember, the middle 75% of the cutting edge doesn't contribute to the cut because the skin is already stretching. Because of the markedly-wider wings of concave broadheads, compared to the moderate tail width of most broadheads, the wound is much larger. Concave broadheads regularly produce wound channels at least 50% wider than the broadhead's width, and as much as 200% the width, depending on impact angle.
  • When the tip contacts skin, a hole is cut and natural skin elasticity stretches the hole wider than the tip, relaxing the skin. Next, the wings of the concave cutting edge slice through the already-relaxed skin which is offering much less resistance, producing an extremely large wound channel.
  • A second , and HUGE advantage of concave cutting-edge broadheads is what we refer to as "dig-in". An extremely angling shot can produce a long cut until the concave broadhead wing "digs in" and directs the arrow internally rather than glancing out.

Why Cut on Contact?

  • By design a better penetrating broadhead. A cut on contact head is in the "boiler room" while the other types are still stretching skin.
  • Generally tougher than other designs. Complete penetration without damage to the head is the norm.
  • Economical. The initial cost and the continued reuse makes it so.
  • Confidence of knowing the sharpness of your blade while enjoying the participation in one of the basic and oldest skills of bowhunting - sharpening

Why should I select a concave design?

 

  • Superior flight characteristics stemming from less surface area which allows any width concave head to fly better than narrower heads.
  • Creates a large wound. The hooking effect of the concave edge or shape doesn't allow blood vessels or tissue to roll around and not be cut.
  • Takes less force to create a wider cut because there is little steel in the hook performing in tissue much like a cheese cutter does in cheese.
  • Allows little chance for a glance off on severe angle hits. Even if the hook touches first, a drag is created keeping the arrow in contact until it bites in.

How can I sharpen the concave edge?

Our high quality carbon steel blades are hardened to be tough while retaining a high degree of sharpenability. Tools that are round, oval, or narrow should be used so as to retain the width of the all important hooking effect. We offer some hand tools that work very well in addition to our Steel Master (tm) angle holding device that will do major edge beveling when required in addition to final finishing. It's very fast and easy to use and is also used on bleeder blades and knives.

Should I use the Bleeder Blade?

A hard question to answer because of so many variable such as:

  • The force your bow delivers to the arrow
  • The weight of the arrow
  • The angle of the shots you generally take
  • The size of the game hunted
  • Terrain hunted (swamp, dense, etc...)

If these variables were known along with where the animal was hit, a very accurate answer could be made.  In most cases, the answer would be to use them.

What will help me get better arrow flight?

  • Determine the shafting and spine that shoots best from your bow and fine tune
  • 5" helical fletching quickly stabilizes arrow flight if needed or desired.

Any Tips on Shooting?

  1. First and foremost, your arrow must be spined properly for your bow weight. This can be easily done by checking the arrow charts to match your bows weight.
  2. To get your broadheads to shoot the same group as your field points we suggest the use of helical fletching, 4” fletching is acceptable, but 5” will stabilize your arrow in flight much faster and give you better overall flight. What most people don’t realize is that the faster your arrow stabilizes the more room you have for error on your part. In a nutshell, 5” helical fletching is much more forgiving, particularly when you make shooting errors such as hand-torque. In most situations, especially in a tree-stand, we need all the help we can get shooting in awkward positions.
  3. The recent development of the “drop away” arrow rest is probably the best thing to happen to fixed blade broadheads. Perfect arrow flight can now be achieved at high speeds using ultra light carbon arrows. We cannot endorse any individual manufacturer, but we have tried several different ones and they all seem to give the same flight characteristics. We do recommend that you look for a simplistic design without too many adjustments and be sure to take note if it has enough drop to fully clear your fletching.
