I used to thought when you sharpen the blade the sharpest edge should be straight line. looks like this
--------------------------------
i have tried Many stones and check the edge 100x to see what is going on with the edge while i progress from 1k to endless.
Always this was the case. AT the end edge was straight line.
Recently i have gotten strange stone.
Edge doesn't come out from this stone as a straight line.
It comes out saw tooth.
in 100x i can see clear it is not straight edge. it is straight saw tooth.
Now i took Blade to shave test 3 times 3 different blades and they will shave as fine as my Jnats or escher used edge only 1 differences i could notice.
it is Cutting nose is different. it seems like winter time you walk on the snow.
Any ideas?
