replacement blades

[Knoodles]

I just picked up an older strikemaster 10inch auger from my grandparents.  The auger bit is blue.  This is a two blade system but the blades are not serrated like the new lazer blades.  Anyone have this type of auger and if so do the new lazer blades work.  Can you swap out the non serrated blades with the new ones?  I cannot seem to find these blades online.

They are mora blades. As far as I know the only blades available are the hand auger ones. They will work just fine
