Good to hear about Leading Edge Sharpening service.
I have a Husquavarna 10" with the curved Lazer blades made by Mora in Sweden.
This year my spare set meant to go to a sharpen service got misplaced so had to go online and purchase new set Just in case.
Fast forward they arrived today $108.00 US dollars later Only supplier was on EBay.
A word to the wise Use a Shovel to clear snow down to Ice. All it takes to wreck a set of blades is drilling once thru a spot where someone had parked and sand and gravel stuck in wheel well dropped on the ice.
