Sharpening chisel grinds on Sharpmaker?

I sharpened my first chisel grind (kinda, sorta, not really), an Emerson CQC7A. (The blade is double ground but the edge bevel is all one-sided, partly serrated). It had been basically dull, now it seems quite sharp. I had adjusted my positioning on the Sharpmaker to fit the one-side edge, only working the one side, then laying the other side flat and with the weight of the knife lightly ran it down to remove any burr. (I did not sharpen it as I would a Spyderco per Sal's advice, on both sides, I decided to follow Emerson's advice for this knife).

My question is, on a true chisel grind (i.e., a tanto-point CQC7B), is it best to only hone the plain portion on the flat part of the rods? I acquired this CQC7B as well, and the edge angle is a bit more severe than the CQC7A, besides being a complete chisel grind. (this one, out of box, is scarier sharp than was my CQC7A was out of box).

Hi James. There's no real "rules". The thinner the edge = the sharper the edge = the weaker the edge.

If you want max sharpness from a hamaguri (single bevel plain edge) grind, sharpen thin on the beveled side (maybe 30 degrees) and flat on the "non ground" side as you did.
