Eyeballing the spec sheet in the Leatherman Library and the product page for the Core, there's not really much difference between the two, is there? The only real differences I see are the replaceable wire cutters and the cut out for the knife blade, yes? I'm wondering if I should just grab a Core from Costco (which I think I saw packaged with a knife for 40 or 50$). Does anyone know if the Core contains those zytel inserts like the Blast and Fuse?
