I would think it would be sharper and stay sharp.. easiest way to look at it is a knife how many times do you have to sharpen the serated part compared to the normal blade 50 to 1 I have a Gerber gator I have had for years I have sharpened the main blade [emoji817] of times but never have on the serated part and it is still sharp. Once I put that fact into perspective it should be sharp even after going through a deer.

Lets ask this....
Would a 1" wide skinning knife or a 1" wide keyhole saw blade push through flesh/bone better?
Which would cut through a rubber band quicker?

I think common sense will answer the question.

 

If you know how mammals tissues clot and scab over, you'd know that tearing cuts with more tissue damage bleed less and clot faster. The more tissue that's damaged, the more clotting factors are released and the faster the wound clots and stops bleeding. That's the last thing you want on a marginal shot. Double lung shots won't matter but hit back a little too far and you want that wound to bleed as long as possible.

 

I shoot both and see no penetration difference. I was of the mind set of razor sharp is better because it cuts and the other prob cuts and tears. I may be wrong but I have always had 2 holes so doesn’t matter really as long as they don’t close up.

Now for target damage the serrated will year the guts out of a good target.

 

Did he say the more tissue damage you do the more clotting and less blood you'll get?

^^^yes he did!! I totally disagree with that statement. Go to Ranch Fairy videos on YouTube. You'll hear the same thing I've said. And he's killed more wild hogs as well as other animals than most will in their lifetime.

Well go become a doctor like I did and when you learn about hemostasis, argue with your professor about it. I'll do you a solid and save you a couple hundred thousand dollars and will give a very simplified explanation why this happens.

When you get a clean smooth cut like from a razor edge, the surface are of the damaged tissue is less but the same amount of vessels are damaged. Because there is less damage to the tissues in the immediate area, fewer contractile proteins are activated so they release fewer factors like ADP, thromboxane A2, among others, which activate more platelets and promote vascular spasm. Less platelet activation means less clotting. Less vascular spasm, aka vasoconstriction, aka constriction of the blood vessels, means there is more blood loss because the vessels stay wide open. On top of that, a clean cut offers less surface area for the platelets to "grab" onto and form the clot. Platelets are covered in sticky stuff called glycoproteins that stick to exposed collagen fibers around the wound edge. Collagen is a protein found in almost all tissues of the body. When there's less tissue damage, there's less collagen exposed and the platelets have less to "grab" onto and can't clot as easily. Platelet activation is also a cascade effect. Once one platelet becomes activated, they activate a few more and those few more activate a few more and the process grows exponentially. Decrease the number of platelets that can find that exposed collagen to begin with and you decrease the number of platelets that will be activated to even begin clotting.

So now imagine a blood vessel....... a long tube full of fluid. Cut that cleanly in half and the liquid will come rushing out all at once. Will it rush out faster if the cut was torn or cut cleanly? The answer is that it doesn't matter. If it's bisected at any point it will come out just as fast because the blood up stream is still confined to the same size blood vessel. Once that vessel is completely bisected, it can't be cut any larger. All the way is all the way.

So, knowing the very simplified process of hemostasis, you should be able to see how it's best to have smooth, clean cuts from your broadhead.

I will qualify this with the fact that if you make a good shot, it won't matter because the animal will bleed out almost immediately and die well before any of this process would matter. However, on a marginal shot where you need to leave the animal lay for several hours or over night, you want that wound to keep bleeding as long as possible. That's where it'll make a difference.

 

Are you agreeing with serrated or non serrated?
I think I would rather have a head that cuts going in and on the back side in case of no pass through. I haven’t had many not pass throughs but the one I did didn’t have much blood, but it died in sight so didn’t matter.

I guess the marginal shot is something like a liver or a gut shot .so there's a disadvantage to more tissue damage. I think there's also an advantage to more tissue damage.

Great answer Huntinsker, I have noticed with working with youth and women with short draws and low poundage the non-serrated fixed 2 blades seem to penetrate more and have better trails.

 

Thanks much for your thoughts on this question, folks.

 

The good Doctor is 100% accurate.
I'd like to clarify "serration" and a few bowhunting specific things covered in my video.

The MOST IMPORTANT thing in this discussion is blade damage, if and WHEN it is damaged, no cutting occurs, no science solves that. I am going to start doing more videos, my moderately "*******" autopsies, etc. to explore this fact. Its sad to think of the animals I've lost and a BUNCH of my guided folks have had "weird" blood trails on perfect hits (when you guide every shot is perfect), especially magnum hogs, but a few deer, I have a hunch the broadhead blades were destroyed on impact. I bet more than a few of you have had broadheads, shredded, and there's a ton of comments on Mech threads about them "being disposable", even when you kill stuff. But it should give you pause - especially on rib hits. Ribs are quite elastic, by nature of being a set of bellows and quite whimpy. If your chosen broadhead leaves you any concern on a rib hit.
Be concerned. Because your broadhead is garbage.

Seriously, that is not hubris. As I like to say "there's a bunch of ribs and stuff" Here's a bad picture of that kind of stuff your skeet load has to penetratte before it kills anything. YES THAT IS 6" OF STUFF before it hits the lungs. Of course if your bow shoots over 335 FPS.........it goes through so fast the blades can't be damaged. RF can only get Pamela to "put out" 200-230 depending upon whats in the golf bag. 6" brace height and IBO be damned.

Anyway, in the Magnus video's we see what Mike Sohm calls a "chiseled serration". I've been trying to find a better way to put it, my buddy Blake Davis said it best. Its' a Blade Interruption. Normal serrations are set up to cut and shred with the tips, they aren't that sharp. So, all of the science and hemostasis reaction, etc. is 100% accurate. The more damage and shred, the greater the reaction from the body to plug the holes and save itself. But, the Magnus Interruption, leaves the straight edge intact, there are literally flat cutting tips and then each interruption is a very sharp scallop. You literally sharpen the broadhead as if the interruptions aren't there. Yes, there is still shred.....hang on......man

The good Doctor is probably considering Xanax or pulling a typing Ninja on me, because we still have Hemostatic reaction to over come and other science.
Here's the bow on the thing.

If you hit something hard and I have spent the last 12 month intentionally pushing the limits of aiming at hard stuff (see golf bag pig video). But let's just say you're the best shot ever. Like Gillingham and some of the blow hard long range guys, they never miss and their shot placement is always perfect, because they are way better than you, I mean 8th grade recess fight better. They also prefer to shoot over 100 yards because its way better.
Taking those 5 guys out, leaves us mortals
So, lets say you accidentally hit a rib dead center or the edge of the shoulder blade at some pecker measuring distance like 27 yards (Heaven forbid the animals jump - 100% jumping in my videos). The edge could be compromised, potential for the blade(s) to flatten and no cutting or significantly reduced cutting occurs. BTW - arteries are pretty tough, you get a rolled edge, they will roll around it, I've done blood gas sticks a ton. Silly things have a mind of their own. Your arrow is going pretty fast and hits a fixed object...well, relatively fixed. It slams into something.

Mike's Interruption is protected to a certain degree. The lung tissue has potential to drop into the interruption, it has potential to at least nick arteries and veins, allowing it to cut at some degree. If the blade isn't compromised, good clean cuts and interruption. If the sharpest, flat part of the blade takes on some damage, interruptions are way better than a butter knife.

I am not a fan of 100% serrated heads. The good Doctor is 100% correct. We don't want to start there.
BTW - this is not supposed to be a Magnus promo. He's the only one with the interruption (I havne't looked closely at steelforce stuff) and the cutting flat (except for my single bevel shredders!!!).

You can always get a chainsaw file and tweak stuff!!!

 

OK so the serrated version does more damage but the Blood Trail is less and you're less likely to find the animal?

On a marginal or poor shot, yeah maybe. There's a lot of factors but if it came down to the hemostasis process of a mammal's tissue, you'd want a smooth cut.

I think we should qualify "more damage" a little too. Say you have the Black Hornet and the Black Hornet Serazor. Both are cut on contact and have the the same width of cut so they will both cut the same width of wound channel through the animal. The "more damage" comes in when we're talking about the smoothness of the cut, not the amount of stuff that is being cut. If there's only 2 major arteries within that 1 1/4" wide wound channel, that's all that's going to be cut by either of them. The difference is that one cut will be very smooth where one will be more jagged. The jagged cut increases the surface area of the severed blood vessel and that allows increased clotting and vasospasm which in turn decreases blood loss.......all things else being equal.

 

Troy:

I have enjoyed your Ranch Fairy videos.
Have you tested or hunted with the Black Hornets without the "chiseled serration"? Do you notice any difference with and without the serrations?

 

Yes, they worked fine. As well as multiple other straight blade broadheads. I will add, the edge integrity on either type of blade edge improves significantly when blade thickness exceeds .05.

 

Let's see what the owner of Magnus has to say about this

Mnarrow I always have to chuckle when I see someone saying the stinger buzzcut chisel serrations are just marketing, this is so far from the truth. The chisel serrations have many more cutting edges on them, each and every edge of the chisel serration cuts and this creates a lot of damage and since it is a chisel serration it doesn't grab hair like a scalloped serration does. We have tested these heads since 2006 when we first come out with them and every single time, penetration is exactly the same as a smooth edge but the holes and blood trails are always better. I shoot 52 lbs out of my compound and I always get pass thrus with our stinger buzzcut 4 blade. Two broadheads are in my quiver, stinger buzzcut 4 blade broadhead 125 grain and black hornet 4 blade ser rated broadheads. Thanks

I practiced with a Buzzcut for quite awhile. That head stayed sharp considerably longer than anything else Ive ever shot. I haven't hunted with them but only because I only had one.

 

Don't over-think this.. Just choose one or the other, make sure they fly right and go kill something.

 

I think this guy is on to something

I cannot hardly wait to send my ser razor 100 gr through a whitetail!
Also gonna shoot a regular bladed hornet as well.
This is gonna be good.

Just shoot em with a 3 inch shwacker and you won't have to worry about any of this.
