Bill,
I am pretty sure the shop etches the others as they are all done on the right side of the blade like normal. As to why the AG Specials were #'d that way... I have no idea, that's just what Gary told me. I guess in hind sight I could have asked him why but didn't think of it when it was mentioned. Scott may see this (if the water isn't too dirty and he's wearing his goggles ) and may shed some light. Perhaps AG just wanted something different from the norm, who knows?
