Symmetric or Asymmeric edge?

Hello all Now that I have figured out the difference in the two edges, could anyone advise me the better of the two edges? And can you still order either edge on the knives? Thanks Bill
 
I think Busse would do assymetric if you want it. As for the difference, think of assymetric as a semi chisel with convex on one side instead of the typical angle. So it has the benefit of a convex grind but half the angle so it will cut much better than most any grind. The drawback is that most do not know how to sharpen it. I think the knives use to come with sharpeneing instructions. I went full convex on my users.
 
this knife has a zero convex edge and it is so sharp that I just shaved parts of both of my arms to remove pizza dough that had dried to my hair. It shaved better than a razor:thumbup:

And the one in the pick has anasymmetrical edge or only sharpen angle on one side of blade?

No that one is not assymetrical. Assymetrical would be half that edge thickness and would even shave better.:eek:
 
Thanks for the info., but now I am totally confused. Symmetical edge would be both sides of the edge ground at the same angles. And asymmetrical would be only edge angle on one side correct? Sorry real new at this..Bill

No, the asymetrical edge has both sides ground, but one side is at about twice the angle as the other, in other words, they are both ground, but not at the same angle. If only one side was ground, it would be a chisel grind.
 
Look at the Badger with the black blade (one on the bottom) in the first of the two photos, titled: Badger Attack III. It is asymetrical. In the first photo see how much edge you can see v. the second photo (where it is the top knife).

Very nice and clear way for making an example:thumbup:! My only concern is how difficult it is to maintain this type of edge? Is there any way someone can access any information with regards to this issue?
 
try sharpening freehand, i use the sharpmaker stones, steel rod, and leather strop. with a little practice it is pretty easy to find the correct angle on nearly any knife.
 
I recall Jerry giving instructions about this here, so just search for it.

It is something like steeling one side and then strop the other, I don't recall which side gets what.
 
Nice pics Tony:thumbup:

That edge on the BA III looks awesome:cool:
 
On an asymetrical edge you have both a convex or curved grind, and a flat grind, /)

The advantage to the Asymetric grind is Geometry, makes the edge last longer and is easier to resharpen by Steeling or stropping in the field.

With the asymetrical grind you get an edge that lasts longer in tests, about 40% longer doing things like Push Cutting rope, while remaining shaving sharpness.

There is more but I am feeling lazy
 
I use an Apex Edge Pro and sand paper for my asymetrical edges. But usually I convert them into symetrical. Not sure about this but I read somwhere that an asymetrical blade tends to pull to one side while cutting. Is this correct?
