single bevel heads

this might be a stupid question but how do you know by looking at a single bevel head whether it is left or right grind?

heartshot  :confused:

heart,
If you are looking down at the broadhead, with the tip pointed away from you, if it is ground on your right edge, it is right grind and you should use right wing feathers.
I hope that explains it well enough.

that makes sense to me...thanks so much

Why do you need to use RW feathers?   :confused:

[owlbait]

Right hand Single bevel heads have rotational penetration to the right and right wing fletch will enhance the penetration, so goes the reports!

[Last of the Breed]

If you are holding the broadhead point away, a right bevel will be ground on the left side of the head.  RW feathers spin the arrow to the right and the right hand bevel will also spin the head to the right, and on impact the head will "twist" to the right.

This is left hand:

Sometimes visuals just clear things up.

Here's a left beveled Zwickey:

   

Here's a left beveled Wolverine:

   

Of course a right beveled head, like a Grizzly, would be opposite of these.

That's funny Jeff we posted at the same time.

Nice pictures!    :D

It's a good thing pics were added.  Had I used the definition provided by John, I would have looked down the blade edge with the point pointed away from me and I would have come up with different answers than Tim and Jeff did with their pics.  I'll be receiving some Zwickey No Mercy Left Wing single bevels shortly, so I would have seen the obvious answer then.

so who is right John or Jeff?

[bowmofo]

So when its laid flat I see! but how does it cut better if the correct fletch is used ?

[britts]

Both!

re: "So when its laid flat I see! but how does it cut better if the correct fletch is used?"

The single bevel head will rotate while cutting through the animal. If the fletch and blade bevel are mismatched, the theory is that the arrow will waste energy while stopping and reversing it's direction of spin upon penetrating flesh. The reported main benefit of  single bevel heads is that upon striking bone, the blade will twist causing the bone to split opening up a gap for the arrow to pass through (improving penetration). The spiraling cutting action of the single bevel blade also may help to open up the wound channel possibly improving the blood flow.

Deff has it right, it's rotation.

Right wing fletching causes the arrow to rotate clockwise in flight.  

A single bevel blade will rotate as it cuts, with direction determined by which side is beveled.  A right hand bevel broadhead will also rotate clockwise as it cuts.

By having them work together, no energy wasted fighting each other, you should get better penetration.

(Left handed is just the opposite rotation, principle is the same)

[bowmofo]

You would think a right bevel would cut counter clockwise? I may be mistaken I'll try it tomorrow  MIKE
