I’ve had this system for a few months so still learning and finding out what techniques work a couple of blade I have re profiled the last blade I sharpened I noticed a gape while I was sharpening so I might not be getting the angle completely towards the back of the blade or dinging the sweet spot, Finding the sweet spot might be the issue also I do get a bur along the whole blade but I might not be doing it completely thanks for the help!!
