sounds like to me you have a mora style auger, the blade will have swedish stamped on them.
I think I have seen lazer jet blades with swedish stamped on them as well.
to know if your is a lazer or mora, the mora has a pair of flat rectangle blades. the Lazer Jet will have a pair of bow triangular shaped blades.
If I remember right the flat side of the blade goes to the mora auger, "some one can correct me if I am wrong." You cant get the lazer wrong because they only go on one way.
now here is the problem if your mora wont cut a hole with new blades, and the reason I dont care for this style auger.
people including my self tap the auger against the ice lightly to knock off the ice build up. When you do that you bend the soft metal frame the blades are mounted to. hence the auger will never ever cut right again.
a sign that this has been done to your auger or it has been droped on its blade is when you attempt to start your hole it wants to skip across or bobbel around on the ice.
if this is what is happening, you can put a peice of shim stock on the cutting side of the bolts when placeing the blades on. It dose help a little, but it will never cut like new again.

this is a power lazer blade
gas and electric, hand lazers look the same with out the serated teeth.
