I have a question that I think fits this discussion. When doing multiple knives of the same, once I put the knife in the jig do i need to complete it from start to polish? Or can i rough grind them all then fine grind them all and so on? I recently picked up some restaurants and I feel like Switching my stone from rough to fine grind on each blade builds up a lot of slurry and uses up the stones faster. Just courious if my thinking is right or am I way off?
