Chisel grind angle?

[skippyW]

What is the edge angle on Emerson chisel grinds? Is it the same on all models? Yes, I know one side is zero degrees.

Every model has a slightly different angle. Use Ernie's sharpie trick. Rub the marker in the edge and once it starts getting stripped away you've found your angle

I have had luck using 35° on my 7a. The horseman I had was right at 40°.
