Bishop Archery Dicing Drill Tool Steel - 100 gr Single Bevel Broadhead

Description

Bishop Archery Dicing Drill Tool Steel - 100 gr Single Bevel Broadhead.
Description from Lusk Archery who has tested many broadhead manufacturers and designs. Please check out the testing videos at the link below. Note that this is the Bridgeport 41L40 tool steel version with a Rockwell hardness of 55 vs 58. Note that these blades are not sharpened. I can sharpen them for you prior to shipment for an additional per package of 3.

Here is a description of the Broadhead based upon his testing:
The head is a single bevel, two blade head. It is sharpened at a 40 degree bevel on all sides, including the back edge and the tip. It has a very stout tanto tip that may look blunt, but is anything but. It is created by two single bevels converging, at a different angle than the main blade angle. It resembles a Helix in design, but is much stouter.
Beyond the thickness and the geometry, is the fact that this head is machined out of a sold piece of Bridgeport 41L40 Tool Steel. This steel has unique properties, not the least of which is its ability to be treated to a Rockwell Hardness of 55, without becoming brittle, as most steels would at that hardness. This is especially significant because it is a single bevel head. As you may know, single bevel heads rotate upon being forced through a medium. This rotation helps in three primary ways, as Dr Ashby and others have demonstrated:
(1) It aids in bone splitting. Rather than just penetrating directly into a bone, it penetrates and rotates, prying the bone apart.
(2) It twists hide, organs, and tissue around itself and thus often cuts more than a double bevel head would. You can compare it to a fork cutting spaghetti vs a fork twisting into spaghetti and then cutting it. You will cut more spaghetti with the twisting taking place.
(3) It creates a circular wound channel that is more difficult to seal up than a single plane wound channel, thus aiding in blood loss.
But the inherent weakness of single bevel heads is there is so much pressure on the leading edge of the of the blade, that they are prone to chip or break. And there can be so much twisting pressure on the ferrule, they can shear off there.
This is where the tool steel is supposed to make a huge difference. It is so hard and so durable and so resistant to chip or shear, that it eliminates the inherent weaknesses of the single bevel head. This, combined with the thickness of the Bishop heads, and the geometry which is supposedly superior to Ashby's designs, allows all the benefits of a true single bevel head with none of the weaknesses.
These Broadhead shoot like field points. Please let me know if you have any questions about the Broadhead.
