When i got my steel heart 2 awile back it was advertised at 1/4". I never thought much of it until i recently started checking out the boards and seeing what the infihogs had to say. I then measured my SH2 and found it to be .287" which falls between the 1/4 and 5/16. Is this normal? I also measured my badger attack and it was .291", never thought it was thicker than my SH2 but the micrometer doesn't lie. Are all busse blades diffrent? I always thought they were ground from the same size bar and should be approximately the same thickness besides the 5/16 which i figured was ground from a thicker bar than the 1/4 models. Any info here would be great, thanks.
