So...What exactly is a "conventional v-grind"? is that referring to a double-v or a v-grind with a chisel edge?

which knives are v-grind and which are chisel?

EDIT:
specifically, the CQC-13 and CQC-8? but i would like to know about other models too
 
I'm pretty sure v grind is a v grind, 20 degrees on one side and 20 on the other side (20 is hypothetical I do not recall what is the angle is). A chisel grind is a grind with only one side sharpened.

See how the V looks like a edge or a grind on a traditional blade.
 
The "v" ground blades are ground on both sides but have the final edge bevel on only one side.

The chisel ground blades are totally flat on one side and have both the primary and edge bevels on the other side.
The only blades with a chisel grind are the CQC-7s, La griffe, Kerambits and Sarks.
There are others but the ones listed are the ones you will see on the EKI site just now.

Nope. None of Emerson's knives have a "traditional grind" (by "traditional grind" I mean the type of grind you would find on the edge of a PE Benchmade or Spyderco) on the very edge. One side is always left unfinished ground, like that you would find on the remainder of the PE portion on the back (non-serrated side) of a combo-edge Spyderco or Benchmade.

Well, in my experience (many EKIs), EKI's "conventional v-grind" isn't referring to the very edge of the knife, it is referring to the primary grind only. If you take a look at the edge of an AK-47 bayonet, you will see the type of edge grind that EKI uses on all of its "conventional v-grind" knives. Here's a link that may help you: http://emersonknives.com/ekEK_FAQ.php#grind

It's kind of confusing, like how EKI refers to some of their production knife blades as having a "satin finish," when in actuallity, they have a bead-blasted finish, and it states so in EKI's glossary, under the term "satin finish." Now, in my way of thinking, a knife blade with a "bead-blasted finish" could in no way, shape or form also be considered to have a "satin finish," but perhaps I'm missing something. EKI is now offering a "stonewash finish," which is a lot closer to a "satin finish," in my opinion, than their previous "satin finish" blades were.

There satin finish was a coating, not bead blasted. They now use a two tone tumbled / true satin finish on the blades described as "satin".

Haze, I'm a little confused. I have a "satin finished" CQC-7, from 2007, that is anything but. It is a bead-blasted blade with whatever coating they were using at that time (perhaps Cerracote?). I have yet to see a true "satin finish" on any non-custom, non-ECA, production piece. Per the EKI glossary, under "Satin Finish," it states, "The term satin finish refers to the grey finish on Emerson Knife blades. This is a bead blasted finish that is then coated with any of several coating finishes that we may use." I am aware that EKI is now using a "tumbled" or "stonewash" finish on some of their knives, but even this is not a "satin finish" by my way of thinking. A "satin finish" is a "satin finish," not a "bead-blasted, tumbled, stonewashed, two-toned" or any other type of finish.

The bit on the out side you and I see and would be described as the "finish" was untill very recently a coating. The preperation for the aplication of that coating is not the "finish".
Make of that what you will but EKI have never had a bead blast finish on any of the production knives.

I have stripped satin and black Emersons and they had what I would call a tumbled finish under the coating.

The old satin finish was a cermic coating that did look more like a bead blasted finish than true satin but it was still a coating.
 
Haze, Now I think I understand. Thank you for explaining!:thumbup: I always took the "finish" to be the consitency of the steel on the blade, not the coating. Now I see I was mistaken as it pertained to EKI. It made it kind of confusing when EKI stated in their glossary, "This is a bead blasted finish that is then coated.....," as I took EKI's meaning of the word "finish" to be the same as mine. Thank you for your help.

On a side note, do you happen to know if EKI's new "stonewash" finished blades are coated? Thanks.

In that text from EKI they describe what a machine shop would call "finishing" as part of a process in the same
breath as describing what a consumer would get on the final product so I can see why that may be a bit confusing.

The new Emerson "satin" blades are raw steel, no coating by the way :thumbup:
 
That coating on my Emerson came off with green scrubbies and 15 minutes...RAW 154-CM!!
