Hello everyone, I am new to the forum. I have been using T8 since 2020 with standard, CBN and diamond wheels, mostly on 8" kitchen knives and a little less on my folder collection. I was so happy when KS-123 came out because of the time economy compared to the Edding/sharpie method. I check my angles before and after sharpening with a laser goniometer. I experienced a consistent difference of 1 degree that the KS-123 is below the reading of my laser instrument. Can anybody in this forum confirm that difference by his own experience?
