When I sharpen a double bevel blade, 95% pop out in the 140 – 155 gf (PT50B) range without really jumping through any hoops. Most of the time, right about 150 gf. Just a basic sharpening. When I see 160 gf or greater, I always suspect that there is still burr. When that happens, a little more deburring will almost get the blade back to expected sharpness.
I have no idea what’s up with that 150 reading. For whatever reason, my method of sharpening/deburring just produces edges about that sharp very predictably. If it’s much sharper than that I am surprised, and if it’s much duller I suspect burr.
It seems that it is common not only for me, but also for others, to generally end up right around 100 gf for single bevel edges. I wonder if there is some similar, common sharpness that folks see for double bevel edges.
So, I’m curious – what sharpness do you guys usually end up with when sharpening double bevel edges?
I'm not asking how sharp you can get a blade. I'm just curious as to if there is some common sharpness for double bevel edges that you guys see after a basic sharpening and deburring.
