I have 2022 kendo's but haven't skied them much as I was babying them and was injured in 2023. They got beat up a bit at Attitash last week so need to tune. I just checked the edge angle on the first ski with sharpie method and it's 4 degrees. I also have the FK side angle gauge and it was either a 3 or 4 using that, but the tool leaves a lot to be desired so I really don't trust it fully. Could I be doing this wrong or is this something that is possible from the factory? They skied well so not sure if I should just sharpen at 4 or file to three. Thoughts?
