Just a caution. I found the M2 to be run too hard for advertised uses of some knives, and suffered some broken tips and chipped edges. They were in the middle of the "highest Rockwell wars" opening battles started by Loveless and his claimed 62Rc.
They saw in M2 a tough tool steel they could push hard, but neglected take into account slicing paper in a paper mill different than more common daily stresses, and especially for combat knives.
They are excellent long lasting cutters, and nothing can take away from that, but most definitely need at least the same respect in limitations which one would accord a very hard D2. This not an indictment against Gerber, but only that they pushed hardness to limit, and what with not near modern precision heat treat controls of that era, some blades might be over the top, while others spot on or just below.
