You are correct. It was taken to ~.009 behind the edge, I'm very happy with it. For the first couple of years I didn't carry it much because it was more obtuse than the design called for, but it slices like a laser now.
One reason I really like the Ikuchi, is because it has the geometry that the Mantra 2 should have come with, in my opinion.
The Air is another that I carry everyday, thin M4 in a dry environment is hard to beat.
