I grind my final edge on a slow running 240 grit, check it on a good stone for flatness, then go back to the grinder for the final grit, then hit the wire edge on a buffer. A lot of my customers send their knives back to me for sharpening, some prefer to do it themselves so I make sure they ride flat on a stone. This is one of the main benefits of a scandi, the bevel is so wide that most anyone can sharpen it. Any spots that are not flat will show up the first time the customer tries to sharpen it.
Grind slow (rpm) and hold steady pressure throughout the grind.
