So reflecting on this.... Do I really even need more than a single diamond stone and a good strop to sharpen broadheads to extremely durable apex hair popping sharp edges? Why even use different grits other than a pretty polish?
Kinda what I am thinking.So reflecting on this.... Do I really even need more than a single diamond stone and a good strop to sharpen broadheads to extremely durable apex hair popping sharp edges? Why even use different grits other than a pretty polish?

Im talking about a single fairly coarse stone with a strop. Which is all that is needed to get a knife extremely sharpAre you referring to a dual grit stone? I suspect you'd want a medium to get the majority of the material off to get an edge, the the finer one to refine the edge even more. The strop to finish and remove the burr. Otherwise I would imagine it would be like trying to dig a ditch with a trowel - sure, you'd get there eventually!
That's what Alex does in one of his videos and he gets it crazy sharp.Im talking about a single fairly coarse stone with a strop. Which is all that is needed to get a knife extremely sharp
Exactly! So why not my broadheads?That's what Alex does in one of his videos and he gets it crazy sharp.
Those too!Exactly! So why not my broadheads?
I would say it would be more that a rougher edge would just glue itself back together easier than a smoother cut edge, that's why you always rough up a surface to be painted or adding a patch to.Those too!
One of the things that Ashby discusses is the clotting cascade and how an ultra fine edge creates better bleeding than a rough edge. The cut with a rough edge blade (like a file sharpened edge) produces the chemical that induces clotting faster. A smooth edge bleeds better and longer.
No, a clean slice does not clot as fast as a rip or a rough cut. There is a chemical reaction involved.I would say it would be more that a rougher edge would just glue itself back together easier than a smoother cut edge, that's why you always rough up a surface to be painted or adding a patch to.
When you progressively sharpen an edge, sometimes what you do is instead of reducing removing the burr you're actually hardening the burr which is useful with certain applications. Field knives don't need to be highly refined you would for fine kitchen knives.
In the stopping video, Alex addresses that at some point the burr might be hard to detect. But he shows it under high magnification and yes indeed there's still a micro burr.
I'll admit that for most of my knife applications, I really don't need to go to these levels. But then again, when I see Alex demonstrate the durability of the edge when the burr is truly removed, I can see the reasons for taking this to the next level.
I can put a pretty good edge (or what I THINK is good) on our kitchen knives but they just don't hold up well. I assumed it was from knife abuse that my wife tends to do. In hind sight, I now believe it's that I'm not completely removing the burr. A burr is weak, and it rolls quickly and the edge is gone.
If I'm going to take the time to sharpen knives, then I may as well make the most durable edge that I can.
And that mindset is obvious when we talk about broad heads. I insist on the sharpest, most durable edge possible.
There's some applications for it. Mostly for skinning and fleshing purposes. If you have a burr that's angled up relative to the skin, it will keep the edge from digging into the hide causing a cutRight but why harden a burr instead remove it
Go to the Ashby Bowhunting Foundation and you can read or listen to the factors that lead to the clotting cascade.It's all about the plateletts. Plateletts stick to the damaged walls of the veins/arteries. They'll catch on ragged edges easier than on smooth.
That report says the same thing I'm saying which you agreed with. The reaction your talking about will take place regardless how sharp the blade was. Amounts of the agents produced would be less with a cleaner cut vs the ragged.Go to the Ashby Bowhunting Foundation and you can read or listen to the factors that lead to the clotting cascade.

The fibrin attaches to the
ragged tissue tags at the cut edge of the blood vessel to form a
clot, sealing off the vessel.
What's important to recognize is that the type of edge
finish on your broadhead has an effect on the clotting cascade.
When you use the thinnest, smoothest, sharpest edge finish fewer
of the cells lining the blood vessel's inner wall are damaged.
This means less porthrombin is released. At the other end of the
cascade this means less fibrin is produced; but there's more.
That thinnest, smoothest, sharpest edge also results in fewer
tissue tags at the cut end of the blood vessel. That means there
are now fewer tissue tags for the reduced amount of fibrin to
attach to.
