I have a Benchmade Emerson and have a question about the edge of the knife. If a knife is only sharpened on one side is that called chisel grind? Also, what are the pros and cons of this type of edge style? Thanks,

Mike
 
Yes, if the edge is only ground on one side it is called a chisel grind. Some Emerson knives(Commander), are ground on both sides but only sharpened on one, this is a chisel edge.

Some of the pro's of this edge type are that it is stronger, as their is more steel behind the edge. It can also be made at a more acute angle, as it is only ground on one side, leaving more steel behind the edge. Many also claim it is easier to sharpen as you only have to worry about one side.

Some con's are that it won't really cut straight as the extra steel will push the blade off. It can also be harder to sharpen if you don't have experience with the edge. It is also not a good for general utility work for these reasons.
 
IMO chisel grinds suck, they always pull to one side, you can get just as sharp an edge with a normal V edge if you thin it out enough, there is no reason for chisel edge's IMO except maybe its cheaper to make since you only grind the edge on one side.
 
My only problem with the chisel grind is that a lot of companies grind the wrong side. when using a chisel, you want the flat side of the chisel to be against the wood. same as when you're cutting. Most brands (for reasons I don't understand) put the grind on the left side of the blade, which makes most cuts pretty difficult for a right-handed user. I don't get why they do this. The same thing is usually done with serrations, but the only blades I have wih serrations are a Spyderco Meerkat and a CRKT Ryan model 7, and both these knives have such good serrations, it hasn't been a problem for me yet.
 
Chisel grind is when only one side of the knife is ground, the other side is completely flat.
"chisel edge" or single side sharpening is when the edge is made by sharpening on one side, and the knife could have a V grind.
The Emerson Commander has a saber grind and single side sharpening.
Some japanese kitchen knives are Chisel grind, but I've yet to come across a sample of a folder with Chisel grind. I know they're out there (and probably Emerson makes them too) but I just haven't seen one myself.
Chisel edge is quite annoying because it tends to veer off, making the cut curved.
