I have noticed that the Emerson Commander is described as Double V Ground. The knife looks like a chisel grind to me. I have always heard it described as a chisel grind as well. What exactly is a Double V Grind and is a chisel grind a version of a V grind or vice-verse? Educate me o wise ones.
 
I've never held a commander...

But I would bet that double V means both sides ground, as opposed to the chisel ground blades (one side ground).

:)
 
It's confusing to refer to the Commander as a "double v grind". It's a "v grind", period. That is, for the primary bevel. It is symmetrically ground on both sides of the blade, not a "chisel grind" where only one side is ground.

But, the secondary bevel is only ground on one side, which gives it a tendency to do that chisel-grind skid off to the side when you slice something slowly. This does not make it a chisel grind, though, which refers to the grind of the main part of the blade.
 
A V grind could be a convex grind or a flat grind or a saber grind or a hollow grind. It just means that the primary bevel is symmetrically ground on both sides of the blade.

A chisel grind leaves one side untouched and only grinds the other side of the blade, generally in what would be called a saber grind, like a woodworking chisel.

I just got a Running Dog knife (thanks, Rugger!) with what they call an asymmetrical grind: unground on the left side and a high saber grind on the right. This is a kind of chisel grind, not a V grind.
