It is the standard cheap knife grind, take a piece of flat stock and just grind an edge, it is how you sharpen lawn mower blades for example. Ironically some makers have been able to push it as a superior grind which would make Barnum very happy.
The fact that they had single bevels really isn't the critical factor, I would look at the steel choice, handle structure, general blade shape, lock construction, etc. . For the price of an Emerson I would expect a primary grind. If you like the angle that a single bevel gives the edge then that is fine, use a more acute primary angle which will increase the cutting ability further and radically increase ease of sharpening, i.e., make a better knife.

so ya are saying an emerson ZBG is a great edc?? how many have you used in that capacity?? i would say the thin edge IS a critical factor, thats pretty much the concensus of most folks who do edc them.
have you ever even seen a ZBG emerson much less handled one?? you sure dont sound like ya have.
also havent seen any lawn mower blades as sharp as my CQC8 either.
sometimes i wonder WTF ya are talkin about............

No, I am saying that the fact that there is a single bevel grind would not exclude it from such consideration which should be obvious because all the cheap utility knives have that exact grind.
Single bevel edges are very thick because they lack a primary grind, the thickness is essentially the full knife stock. The bevels are essentially formed from low sabre primary grinds and thus about 10 degrees or so is standard. I EDC knives which are both far more acute and thinner than any of Emerson's knives.
A. G. Russell's Deerhunter which many will carry as an EDC knife has an edge of about 0.010" thick and ground at about ten degrees per side. Many of the newer Spyderco's with high flat grinds are coming in at similar profiles. Measure the thickness and angle of your single grind emerson and see if it is significantly more acute in profile.
I leave mine as filed but you can polish it up to 0.5 micron if you want. How can you possible contend that adding a primary grind to the knife which is more acute than the existing edge bevel on a single bevle grind reduces the cutting ability of the knife? This should be obviously absurd which means that the single bevel knife has a lower than optimal cutting ability. It is used simply because it is cheap and that is why it is the grind found on $0.25 disposable utility blades.

A couple definitions seems to be in order.
Obtuse angle: an angle between 90 and 180 degrees
Acute angle: an angle less than 90 degrees.
Acute or more acute: Having a smaller angle measure in degrees etc. E.g. 15 degrees is more acute than 25 degrees.
Obtuse or more obtuse: Having a larger angle measure in degrees etc. E.g. 25 degrees is more obtuse than 15 degrees.
Zero grind edge bevel: A knife that tapers at a constant angle from the spine (back) of the blade to the edge of the blade.
FWIW. A zero grind edge bevel requires more metal to be removed in order to sharpen the edge because you must remove steel from both sides of the blade in their entirety to preserve the constant angle/taper of the blade.

Rus, that is not how the term is used in Europe - home of the zero bevel. There, the term refers to a knife with a single bevel, whether from the spine to the edge or from a line soemwhere between the spine and the edge.

Not that I have purchased. The less expensive ones are saber/flat with the flat grind beginning more than half way down towards the edge. The ones I have that are saber/convex are Rosellis and Fallknivens.
still wanna know have ya ever seen a emerson ZBG or used it as a EDC???
dude i'm telling ya they aint the best edc utility knife - i have used mine as such and while they will work "ok" that aint what they were designed for i dont care what mora designs theres for, also have talked to several folks who use them as edc and blade chipping was/is a problem , what are ya saying "dont believe your lying eyes"??? and again while they will work in that role, really ANY knife with an edge will work as a edc utility knife, they aint the best for that. i dont have to measure this/measure that to prove that to myself lol i know its a fact.
but then again as you havent ever seen/used one, and i have, WTF would i know about 'em, huh??
Excellent point Mr. Litton.
I did in fact forget that variant. I stand corrected.
