i have a 8 in. mora gave to me froma fella that went gas and i got some new blades in the deal man oh man what a cutter i have no problem but you have to pace yourself kinda like drill a hole set you tip up drill another or maybe drill two than set your stuff so on and so on . before then i used my buddies gas auger when i went with him or i didn't go lol
and i'd say there are 150 -200 holes on my blades for to start off this year if the ice ever gets here lol.
hope they make it this season as i tried to sharpen the old ones and they will shave hair like no ones bussiness but just shave the ice like a blender chunks and all not wrth a hoot but them new ones whow can you say slushy anyone .
