Just FYI but there is now 2 versions of D2, the regular D2 and the CPM Powdered Metallurgical CPM D2. They have the same composition but the CPM D2 because of the ways its made is the SUPER version oif the regular D2. It can have a keener cleaner edge while at the same time is more corrosion resistant. CPM D2 is tougher at the same hardness. Kershaw has 3 folders using CPM D2 but in a new way. They stuck the CPM D2 to regular stainless steel as the edge and made it look like a hamon line.

Spyderco made a Military out of CPM D2 but I think that those are sold out.
There is also a variant of the regular D2 but tempered in a different way. Its called Friction Forged D2. Only available so far from 1 maker and they make only fixed blades.
