I have my Strikemaster Solo Lazer Pro 8″ for the last 3 years and this past weekend slapped on a new set of lazer blades because I decided to do something dumb. Attempt to sharpen my blades by using one of those retail auger blade sharpener purchased from fleet farm. No matter how sharp the blades look to me it render my auger useless as it wouldnt cut or grip ice after this at all.
But before this I had purchased an Otter Auger shield and have felt that the shield may have dulled my blades from the beginning. The first year I purchased my Solo it was cutting great with absolute no down pressure needed. Half way through the season I decided to invest in the Otter shield to protect my auger and blades and that where it the issues started. Once I started using the otter shield I notice my blades werent cutting as good and would have to use minimal down pressure. The blades have trouble gripping ice without minimal pressure. Even had the auger bit tested at D rock for pitch issues to make sure. I had the feeling that the blades were rubbing up inside the shield and have contributed to dulling the blades even though they looked very sharp with out any dents or visual damage.
So I continue to use the auger as is and stopped using the otter shield. After making the mistake this past weekend of attempting to manually sharpen the blades I swap to brand new blades that I carry as a backup. Wow what a world of difference. The auger was cutting like I had just purchased it new and used it the first time on the ice. And absolutely no down pressure was needed.
I currently use the snap cap to to protect my blades and am very hesitant on using the otter auger shield again due to scare of dulling the blades.
