Hi everyone, just got my blades sharpened yesterday for the first time after having shims put on to help withy pronation, spent 2 hours on ice today and for the life of me could not get over my left outside edge going backwards which is not normally a problem. Had a look and after a lot of squinting and lining the blade up with horizontal surfaces and using a straight rule to check the edges (as described by tstop4me elsewhere on this forum) the left outside edge looks ‘higher’. The right blade has no perceptible unevenness, but I only have a very thin shim on the right, the left boots shim is thicker as my pronation is worse that side. It occurred to me that the uneven edges could be due to the shims as they were sharpened upright on a ProSharp machine, anyone else experienced this? If so should I get my blades sharpened by someone else on a different machine that is less likely to do this?
