The blade is a gorgeous chunk of M390. The ergos are very good, as there are no hot spots.

Button lock is solid, and action is as good as it gets. No blade play, or lock rock, super solid knife in everyway.

The only con for me is the very sharp edged thumb studs that chew up thumbs and spits em out. I had to file the sharp edges where the thumb comes in contact. Then had to wait several days for thumb to heal, to use again. But now I am very happy again.
