VPA Broadhead Battle: Single Bevel vs Double Bevel
Вставка
- Опубліковано 27 кві 2021
- This is a comparative test of 2 models of 150 gr VPA broadheads--the Classic Double Bevel & the New Single Bevel. Which one do you think will prevail as the winner of the this broadhead battle?
I have also picked up a new sponsor with my top recommendation for Broadhead Sharpening. staysharpguide.com or @Innovative Outdoorsman The support I get for that has helped me improve my channel.
I want to explain a bit about the testing protocol that I'm using at this point in 2021.
I have a new test for edge sharpness and edge retention, using the Edge on Up Sharpness Tester. I test it out of the box and then again after Penetration Test 1, to see the edge retention. I also have a different test for flight--shooting one field point and two broadheads at 40 yds to see how well they group. And then I have a new overall Lusk Grade that I assign to each head--they receive anywhere between Zero and Ten Golden Arrows.
Here is my sharpness scoring scale, using the Edge on Up Sharpness Testing Machine:
First of all, what are some common scores for other edges? Here are some examples:
A butter knife takes 2000 grams of pressure to break the co polymer wire.
A new high end cutlery edge takes approx 375 grams of pressure to break the wire.
A utility razor blade takes approx 200 grams to break the wire.
Based on the many broadheads I have tested, here is my scoring scale:
Out of the Box Sharpness:
0-200 gr: 10
201-300 gr 9
301-400 gr: 8
401-500 gr: 7
501-600 gr: 6
601-700 gr: 5
701-800 gr: 4
801-900 gr: 3
901-1000 gr: 2
1001-1100 gr: 1
1101+ gr: 0
Edge Retention: Sharpness difference after Penetration Test 1:
10 minus 1 point for every 50 grams of sharpness difference. For example, if the initial sharpness was 400 gr of pressure and the sharpness after Penetration Test 1 was 450, the head would receive a 9 for Edge Retention Score.

The Rolls-Royce of broad head testing is now you. There is no other in your class.
Agreed
Thank you Jack...that's really encouraging to hear. I've worked pretty hard to keep improving the testing over the years, and will keep doing so.
@@LuskArcheryAdventuresfirst place i come if i hear about a new broadhead or considering one..plus your a believer. ❤ pray for me pastor..struggling bad in my walk. Let sin in and been in a web since. Scared of where im at
I really like your broad head tests, keep up the great work!
Thank you Justin. I really appreciate it brother.
Very helpful video! I’ve been looking at those 150 grain single bevels. You just made my decision easy. Thanks a lot!
Very good. Thanks Ron!
Wow, you have really upped your game on the broadhead tests since the last time I watched one of your videos. Great comparison. I like that you have a better way to measure the sharpness now. I am going to look into those single bevel heads now.
Thank you Art. I've been really trying to keep improving. I appreciate the encouragement.
Excellent video John. And really nice to get to see two broadheads on one video, great touch. 85F or so in Lafayette today. :-)
Thanks Dozier. I love Lafayette!
John, Great comparison and amazing review!
Thank you brother. Excellent job on the heads.
Great test pastor john .. as always enjoyed the video
Thank you Benjy.
That was Awesome, looking forward to more ... 😎🏹
Thank you Cosmo!
John, you must have ESP! Today I just finished shooting the VPA double bevel along with the Iron Will Solid and Valkyrie Blood Eagle. All 150 Grain from Broadhead Connection. All flew well but the VPA was the winner. Shot right with my field points out to 50 yards. From a crossbow @ 360 fps. Think I'm going to try the Single Bevel though, especially after watching your video. I learned about broadhead connection from watching your videos and ordered the broadheads to test based on results from your videos. Even though you hadn't teste the VPA two blade yet, I thought it would fly well based on what I've learned from watching your tests. Thanks and great timing!
Thanks Daniel. Sounds good!
Curious to see a direction comparison of the VPA single bevel and the Iron Will single bevel. Both seem to be top notch regarding higher end SB broadheads.
As always, excellent job John. Keep up the great work
Yeah, that would be a good one. Both have their advantages. I really like the bleeders on the Iron Will.
Good stuff John! VPA makes the best affordable heads on the market. Tough, accurate and manufactured 40 miles from my home in Ft. Wayne, Indiana USA. These single bevels are a breeze to sharpen and fly like missiles. Based on our testing, the VPA single bevel head is the frontrunner to be on the tip of our arrows for the 2021 Indiana deer season. Your testing and other sharpening content confirm that choice as the correct one.
Thank you brother. Great comment. Thanks for sharing that.
Outstanding.
Thanks Jason.
Good vid.. Great looking heads
Thank you
I was very concerned on the tip design on the single bevel, glad you confirmed it’s not an issue whatsoever
Yeah, it's the same design as the Bishop Archery Scientific Method...very simple and very effective. Super easy to sharpen.
@@LuskArcheryAdventures looking at it, it’s just a flat surface and that worried me for penetration, but I see it’s an actually sharp blade instead of being a flat tip
Two very awesome heads for sure. With the higher Rockwell rates on both either is a winner, IMO. The arrows and insert systems is very impressive too. 👍👍👀
Yep. Thanks Tim.
John, Exceptionally good video. Your videos are always well done and very helpful for all of us. I have a question, will the stay sharp sharpen single bevel broad heads? Thank You, John!!
Stay Sharp makes a specific sharpener for Single bevels, based on the bevel angle of the head.
John, another great job...thanks! Since the tip of your arrow’s insert seems to be a larger diameter than the base of these broadheads’ ferrules, might that be hindering penetration just a bit?
It depends on the head, but it's consistent with all my tests.
Vpa has always been my favorite 2 blade
Yep--good stuff. And this new single bevel is really top notch.
Great as always John, sb seemed best, would it be a hassle to do a 45 degree deflection test on these bh battles?
Thanks Mark. I used to do that on plywood--but every head did fine with it, so I felt it was kind of a waste of time.
Killed a doe on opening day with the single bevel. Phenomenal performance, they offer a left bevel now as well
Congratulations! Thanks for sharing that.
I have to agree with you. The test was very fair for each type yet the single bevel slightly outperformed the double bevel. Either would be a great broadhead but after watching the video, given the choice I'd choose the single bevel.
Thanks Frank.
Single bevel was the easy winner. The first time I watched one of these, I wasn’t sure what to think, but now it’s my go to favorite comparison videos. 👍🏻👍🏻
Thank you. I have since realized that the rotation of a single bevel adds an extremely minimal amount of total cut. I got a Physics Professor to give me a formula for it, and for 1" head that rotates 90 degrees (which none have ever done in gel), you get a total cut of .031" more.
@@LuskArcheryAdventures I used the SB on Cape Buffalo, my arrow setup is unconventional by today’s standards, total weight 578 gr with 17% FOC. I was fortunate to have both an entry and exit wound, there was no obvious rotation that I could see, yes it possibly could have rotated 180 degrees, but not likely. I wish I could post photos. It’s nice have real results to compare to the theories.
It was a very interesting test, since in my area we mostly hunt cinder blocks and masonry bricks, they're invasive species 🦺👷♂️😅
Just kidding, couldn't help it. It was a great test, informative and well done! 👍
Haha. Thank you!
Great test, amazing how much better the SB did. I’ve heard some say that single bevels tend to produce weaker blood trails than DB. That never made sense to me, have you found that to be true?
Blood trail is determined by many factors, and double vs single bevel plays very little role IMO. Shot placement and getting a pass through have far more of an affect on blood trails than whether or not one or two sides of the blade are sharpened.
That's a fallacy, Kelley. As Barak said below, blood trails is about 90% shot placement. Even with the exact same shot placement, animals vary in their specific anatomy and whether their lungs are full or empty makes a big difference too. So it's really impossible to "compare" blood trails.That being said, ALL THINGS EQUAL, If you cut more tissue and if you cut a wider hole, you'll get better blood. Again, ALL THINGS EQUAL, single bevels will make a better wound channel & cut more tissue, so will theoretically produce more blood letting. But again, it's mostly shot placement. I've taken hundreds of animals--I've had tiny two blades produce incredible blood trails and then huge 4 blade mechs produce zero blood.
Both good heads for sure. I'm a big fan of taking shots 30 yards and under. Without a doubt these heads would do complete pass thru shots.
Absolutely. And my goal with heads is to: 1. Get a pass thru and 2. Cut as much tissue as I can while getting that pass thru. That's why I like the single bevels, cause you're going to get more cut due to the rotation.
Can confirm they punch right through. Havent had any contact with heavy bone yet but not worried about it if I do. Pretty bizarre considering how the tip is basically flat but if you get those edges to a super sharp state it moves right through tissue like anything else. Smoked a doe on opening day with these singles and she went 30 and piled up. Edges take a while to get sharp but rehoning it after shooting her was a breeze they barely lost any
Another great video. I wish they made a left bevel.
Thank you.
Just saw your comment, they do now. Gonna get some for my recurve next year
Did you do the rotation test with the double bevel? The owner of Day Six gear, was trying to explain to me that double bevel will rotate just as much as single bevels? I was trying to argue with him as I was shooting the Strickland helix and said they are hard to pull straight out of my foam targets, because of the rotation? He was try to tell me double bevels are superior heads and single bevel are essentially out dated. But he was very Adamant about the double bevel rotating just as much as a single bevel but I did not see that in your test I’m wondering what your opinion does a double bevel still rotate as much as a single barrel??
He's wrong. The arrow is rotating in flight from the fletching, and that can continue a bit--based on the medium it is penetrating thru. But the single bevel, provided the blade is thick enough, will promote even more rotation while the double will not. Just look at all my rotation tests of single bevels--they have varied from 8 degrees to 70 degrees based on the thickness, bevel angle, and cutting diameter.
I like the single bevel and am probably going to switch to them
They are a great choice. I wish they had a bleeder, but they are really good even as they are.
Can you do a test on Bishop single bevel Pipeline SR Stainless steel in 200 gr, against the VPA single Bevel PTS in 200 gr and compare both thickness in blades and what bevel they have in degree. Thanks
Thanks for the suggestion, James. Unfortunately, I don't have any of those heads to test like that.
Which 200 grain broadhead would you choose between VPA Single bevel or the Cutthroat single bevel with the Tanto tip?
I'd take the VPA. The bevel angle is much better.
You do good tests. Id rather have a slicktrick that blows through anything than a big clunky concrete shooter.
Well the STs have done very well against the concrete as well.
Nice. Vpa start making 300 grain single bevel. I'll buy some.
They are nice!
I didn’t catch it in the vid, but did you sharpen the double bevel prior to penetration tests or shoot then as they come out of the box?
Out of the package
We need a Lusk/Ranch Fairy collaboration. The 2 best in the game
I like a lot of Troy's stuff too.
I agree with this statement
I haven't seen their single bevels in person, but I know the VPA doibke bevels are dull as heck when they arrive and require sharpening before hunting. That could account for the high numbers on the sharpness test.
Yes, I tried to note that in the vid; they're designed to need home sharpening.
Yes and they take a minute since the steel is so hard. But very easy to bring back to sharp, smoked a doe opening day this year with one and it's back on my quiver after a few minutes on a stone and strop
I'm not sure if it's been commented to death but what about the the megameat test?
Man, I'd really like to test them. I've tested the Deadmeat a lot, but not the Megameat. If someone sends me a pack, I'll gladly test them out. My budget for buying heads is overdrawn :)
Single bevel broadheads are awesome. I wonder why they chose not to incorporate a tanto tip. Does VPA manufacture Cutthroat broadheads?
I like the lack of a tanto tip--just like the Bishop Scientific Method. From the way it performed on the concrete, you can see it's not necessary if the bevel is steep enough and the blades are thick enough and the steel is strong enough. It makes resharpening a breeze.
@@LuskArcheryAdventures Interesting, that is a valid point.
Just realized there are two different “penetrators”. Those with a tanto tip like I have, and those without such as this video shows.
I’d also like to point out that the VPA single bevel out performed the Iron Will Single Bevel you tested 3 months ago. This is a great contender for my next broadhead.
They're different based on the weight of the heads.
VPA SB is harrrrd to get sharp.
@@TheDonsRiche I’d use Diamond Plates to sharpen these, wouldn’t even play with sandpaper.
@@ThumbsMcThumb thank you for the advice! I think they have more potential than the tuffhead evo, but damn those are sharp
@@TheDonsRicheThe VPA SB is super easy to sharpen if you use diamond plates for your first couple of grits. I went DiaSharp 300, DiaSharp 600, King 1000, King 6000 and finish stropped on newspaper and it only took me about 5-7 minutes per head to get them straigt razor sharp.
Why do you think this single bevel held up better than tuffheads? I understand the bevel angle is steeper, but it’s only high carbon steel as opposed to s7
The bevel angle makes a HUGE difference. For example, with the Iron Wills, they first came out with a 27 degree bevel, and I tested them and saw quite a bit of edge chatter. So Bill re-worked them to 32 degrees and they held up much better. Those 5 degrees made a big difference. Now compare a 35 degree to a 20 degree and you can see the difference. Actually 45 degrees is optimal for durability and rotation, but they don't "feel" very sharp at that angle, so companies lower the angle in order to get the sharpness feel they desire. That being said, I do wonder if the S7 on the Tuffhead was flawed in hardening. I didn't expect them to bend like that.
@@LuskArcheryAdventures thank you so much! Yeah I’m most confused about the bending
Hello John. What did you use on your Cape Buffalo Hunt?
I used a Bishop Scientific Method. I show it in the Cape buffalo video as well as the Arrow Build Video before that hunt.
I’ve killed 2 deer w vpa DB. Try r excellent. They didn’t have SB at the time. Next ones I buy will be SB. But those DB are nasty
Thanks for sharing that. Well done.
Single bevel for the win!
:)
Single bevel had a grudge against that cinder block
:)
I don’t really understand why people would want to deviate away from the single bevel. The whole single bevel premise is that is creates a huge amount of torque in rotation. Adding another bevel greatly reduces that rotational torque.
Well, the drawback to that argument is that that rotation also impedes forward momentum. That's the toss up.
That looks just like bishop archery scientific method head
Very similar design.
Anyone hunt with the vpa sb yet? Just ordering a set now.
I've not, but they sure are a solid choice for a single bevel two blade.
Which is better for bleedig ability?
The single bevel.
Single bevel for sure….
:)
The edges these heads come with is terrible for the price.
Yeah, I've heard that.
Both of them was really dull
Pretty easy to sharpen though
Vpa heads are dull as hell geez
Yeah. They plan for you to sharpen them up.
Same steel? One blk one green.
S7 and carbon steel.?
Just a thought.
I believe these are the same steel.
