Choosing a 2 blade broadhead...convex, concave, or straight?

[threeunder]

For the guys shooting 2 blade broadheads, do you prefer a concave, convex, or straight design?

Bear razorhead they have stood the test of time. I guess there convex but never gave it much thought.

[Zradix]

straight...I find them easier to sharpen.

I like the VPA 2 blades, but I'm a little biased.

P.S.  In all seriousness, our 2 blades are an excellent broadhead.  If you have any questions about them, let me know.  Lots of other good 2 blades out there too.  I think if I wasn't so impressed with the VPA's, I would be shooting a Grizzly 2 blade.  I looked at them while up at the K-Zoo show and Bill really has them looking good.  So they're another one to check out.

I have shot both convex and straight edge 2 blades and really can't tell a difference in them. I think the width and length of a broadhead is what really makes the difference.

I REALLY like my GK Silverflame XL's. I guess they would be considered convex.

Convex is my preference.

[Roger Norris]

I prefer straight. Easier to sharpen for me.

[onewhohasfun]

Which ever one you can get the sharpest.

I like straight.

[Red Boar]

I really like Silver Flames convex blade, but I had difficulty getting a consistent edge.  I changed to the ABS Samurai with a straight blade...much easier to sharpen.

Ace broadheads are awesome. Cheap, easy to sharpen, fly great and are super durable. Love them.

[Trumpkin the Dwarf]

I am shooting the Simmons Treesharks. so a definite concave edge there...

[Fletcher]

Straights are easier to sharpen for me and what I normally hunt with.  Convex is probably the toughest point; convex looks cool.  They all work quite well.

[Southern Sam]

Simmons heads for me with a concave edge!!  They create larger holes than straight or convex.

[John McCreary]

I've tried several over the years but always seem to come back to straight and wide the Zwicky Delta and Magnus being the best. The ACE standard would be my next choice, convex, but still easy to sharpen. The concave, such as the Howrd Hill style, is good in theory but I found it very difficult to sharpen. Tom Mussatto, who had a great tutorial on sharpening these heads, may contest that point.

Straight for me. STOS and Abowyer are my favs, a long cutting edge work well too.

[Shedrock]

Straight for me as well. STOS is my 2 blade choice.

[LCH]

Concave Simmons for me I get them sharpe quick and they leave bigger holes more consistantly with great blood trails.LCH

[magnus]

I like the straight also.

Some things to consider in your choices.

Even a round head does OK on a direct broadside, but as you move away from broadside you start to see an angled impact.  If the blade is narrow and somewhat pointed, a straight blade, like maybe a Zwickey No Mercy or Grizzly head, it has a certain point profile that contacts the animal and allows point on impact at very sharp angles.

It might TEND to not be deflected and enter the body more in line with its travel.  

If the blade is very wide,  or if it is convex or concave,  more than the point might make contact with the side of the animal in a very angled shot.  In some cases (I have seen this first hand) the sides of the head contact the animal before the point and cause it to deflect, skid along the side of the animal or even flip out of line.  You have seen some pictures here with some broadheads "opening up the animal" for numerous inches.  This is the likely reason for that to have occurred. No it won't happen all the time, but it can.  If the blade hits the animal in an up/down position, there is no problem, if it hits with a flat position. .  possible difficulties.

IF you get enough penetration, into the right area,  well great.  But if that causes the blade to skid, open up the animal, and hit further back or forward and not so deep, you have a very injured animal that looks like hell running away.

Just a thought
