The EDC-2 is slimmer, lighter, and less expensive than the original EDC-1. It accomplishes all three of those with the removal of hte detachable wrench feature found on the EDC-1. The EDC-2 also features an improved Phillips driver and a thinner slotted driver. The Emerson Commander inspired, 440C blade is still present as is the wicked self-defense implement masquerading as an awl.
The Emerson EDC-2 is available with FDE or OD Green G-10 scales. Check it out at Emerson Knives.
