Hand ground or CNC'ed?

I am currently stripping a CG Bushwacker and I believe this is the first blade I've done that looks like it was hand ground on a belt as opposed to being buzzed out on a CNC machine. Pretty sure it is the oldest Busse I have done too. Anybody know if these were actually done by hand?
 
Cant remember, is that full height flat ground? not sabre? There have been other reports of full height flat ground CG blades being very clean under the coating.

This one is kinda full flat but kinda sabre too. It's like the entire grind is one big convex (if that makes any sense), and on each side it still has a strip of the small INFI dimples a little ways down from the spine, like it was ground on a slack belt.

You nailed it. I just ran across this:

(this is a screenshot clip of the original ad)

The BWM CF is about .20" thick and also has a convex grind.
The BWM LE is .220" thick with a saber grind.
