I get the impression most sharpening is done using each stone grit on both sides and progressing to finer grits.
Is there a reason not to complete one side at a time going from the first to last stone on one side then doing the same sequence on the other side?
Theoretically you could, but the problems with that are:
1. you will probably have uneven bevels
2. large burr formation and over-stressed apex which will lead to a weakened edge
3. problems w/ burr minimization
🙂
but you could work one stone for a bit, then use the other hand and work the other side with an equivalent stone for a while before moving to a finer grit – I do that all the time.
