Mora’s work. They just do. Been around a long time and aren’t going anywhere any time soon. Given that most Mora style augers are virtual copies of the StrikeMaster, I’d give it an 8. Like the Dr. said, blades are available almost anywhere and can stay sharp a long time. I can’t fault Eskimo’s “Mora” style augers either. My first auger was an 8” “Mora” Eskimo. Still works just as good as my 8” Lazer 8 years later.
A lot of things factor on to the “best” hand auger. Cost to budget, blade availability/cost, customer service, aftermarket service, build quality, etc.
In my experience, I’d put Eskimo on par with StrikeMaster cut and quality wise. Can’t really go wrong with either, IMO. Having said that, I really enjoy my Lazer. I’ve considered downsizing the 8” on my Milwaukee with a 6” Mora style auger. Between StrikeMaster and Eskimo, it would all come down do which one I could find cheaper.
