I've skated on Wilson Coronation Ace for many years now. Eclipse at one time had a knock-off, the Mist. But it was also carbon steel and cost more than than the Coronation Ace. No motivation to try it. The Mist has been discontinued and replaced with the Aurora. It is only $25 more than than the Coronation Ace, but it is made of 440C stainless. Very tempting. Anyone here switch from Coronation Ace to Aurora? Is the blade pattern essentially the same? Does the Aurora require less frequent sharpening?
