File sharpened “toothy” edge vs razor sharp polished edge?

From a physiology standpoint the more jagged the cut the more clotting is activated as the chemicals that trigger the clotting cascade are released be damaged cells. So if you damage twice as many cells for the same width cut you trigger more clotting without increased hemorrhage.

If the blade angle is the same I don’t see how a more or less polished edge would dull faster. Does anyone have insight on that?

In my experience, you can polish edges without actually achieving a refined apex. Leaving the burr on can make an edge feel super sharp but it will dull quickly. Likewise, it’s possible to round over the apex using softer polishing wheels or poor stropping technique. You can see your nose hairs in the reflection, but if the apex isn’t refined properly it doesn’t matter.

I don't think thats true. If you think you have a grabby sharp edge check the opposite side of the bevel to see if it was just the burr you are feeling.

There is a lot of info on testing the best edge and steel on Bladeforums.com. The competitions where they cut through Manila rope are probably the best determining factor on what works best in our case with BH's. I have seen a couple of guys comment that they hone the edge down then hit it with a rougher 400 grit diamond. I've seen others that are a big fan of a micro bevel at a wider angle to make the edge tougher.

We need them sharp but also a little bit durable as the head might encounter bone.
The design matters too. The longer tapered designs put less dulling pressure on the bevelled edge. The short heads chop their way in with more hair, hide and bone contact which can dull an edge fast. It's all a trade off and thankfully just about everything works most of the time.
