Single bevel 3 blade head?

[Zradix]

First off I'm not trying to bash anyone here.
Most likely this will be one of my many displays of ignorance in public..lol

I've heard about a new single bevel 3 blade head.
Isn't the benefit of the single bevel head supposed to be the bone splitting/breaking action of the head as it spirals deeper into the animal?

I would think a three blade head would sort of negate this bone breaking effect. I fact I would think it might be very hard to split heavy bone with a 3 blade head. Seems like you'd want it to poke straight through.

Don't get me wrong..I know just about any sharp head makes dead.

I just would like to understand the idea behind a single bevel 3 blade head.

Please give me an education.

Thank you.

The inventor is a member and I am sure will post here shortly.  The single bevel three blade should rotate as it cuts thru the animal and may make a huge wound channel.  I think your right.  The 3 blade single bevel is less likely to penetrate as far as a two blade single bevel.  More surface area = more friction = less penetration.

The head is the Phoenix, made by Red Feather Archery. Stan is a great guy. The idea as told to me by Stan, was not so much in the twisting of the head, but in the angle of the cutting blade. They are also teflon coated to assist in penetration. They are a very well made head, and I am using them this year on mule deer, elk, and moose.
I hope to have great field test report at the end of Sept. I am sure Stan will chime in and elaborate.

Zradix, great questions!

Ryan, is right when he states that originally, I designed the Phoenix as a single bevel to decrease the blade angle.  Double bevel three-blades sharpened two blades at a time produce a 60 degree bevel.  We sharpen ours at 34 degrees, by definition 26 degrees sharper.  Given the quality of the steel used in the construction of these heads I had no worries about the integrity of the steeper angle holding up.

I knew from playing around with some prototypes that I'd made from old MA-3's that I could come up with a number of ways to sharpen them and that sharpening by hand really isn't that hard.  I also discovered that I could make them really, really sharp.  Turns out a member here, L82Hunt, found an even easier way to sharpen them with a Redi-Edge.  Because we're no longer dealing with a 60 degree bevel these types of sharpener become viable.  Here's a link to a video that Glenn made;

You can see how effective it is.

Although this was my initial intent the rotation that the single bevel causes has proven to be very valuable as well.  I'm not sure that a 3-blade head of any design will out penetrate a two-blade head for the reasons Clay stated above, but I do notice an increase in penetration with this head compared to traditionally sharpened 3-blades, especially through hard surfaces.

In testing this broadhead in 3/4" plywood, frying pans, broadhead targets and just about anything else you can imagine this is what I'm finding.  The rotation that blades apply seem to increase the size of the wound channel at the very center of the cut, where the shaft of the arrow must follow.  This appears to decrease the drag on the shaft allowing for increased penetration through hard substances.  We've killed hogs and turkey's with this head with pass-through's and to date they've performed very well on bone, but more real world testing (hunting) needs to be done to determine the effect on bone.

I hesitate post a lot of my findings, because I don't place a lot of stock in promoting my own things.  There's a lot of room for skepticism because I'm the one selling them.  It's why I'm very excited to see what other people post from their experiences.  So far, all the feedback has been positive.

We did have a couple of guys do an independent review of our head.  They do a lot of product testing and have no affiliation with our company.  Their video is posted on our website, check it out.  They shoot with both a longbow and a compound so I won't post a link here.

They have a penetration test on the video that they've done with all of the heads they've tested consisting of shooting through thick rolled up plastic.  They have never had a head penetrate all the way through all ten layers of the plastic...until they shot a Phoenix at it.

Thanks again for the questions.  If I haven't answered them well or if you have others please let me know.  I am leaving tomorrow, however, on a muley deer hunt so it may be a while before I can answer them.

Thanks a lot for the reply.
Now I understand the theory behind them.

Good luck on the hunt!!!
