Years ago I coworker brought a nice JA Henckel knife to work for me to do something with.
It was in the shop I worked in and I used the white grind stone to do it.
The same one we used to grind profile knives for the shaper.
My boss came by and said you are putting a 100 dollar knife on the grinder, in shock.
I hadn't started yet and showed him the knife.
He was flabbergasted it looked like someone had used it to cut stone.
Round on the cutting edge with nicks.
His reply was, "Well I guess you dont have much of a choice".
The coworker had received the knife set as a wedding gift and had no idea how expensive these knives were.
Of course the blade spent more time in the water cooling than it did on the grinder.
Then I finished with a smooth cut file and then India stones.
