There IS a difference, at least on some of them (but it is a small one). After reading through the post, I went down to Fry's to check out the great deals on the "eurosport" (econowhatever, same thing) version of the climber. For eight bucks, I picked one up. The one that I bought has a different can opener blade-thicker because there is no grinding except on the actual edge (the regular versions have always had an almost saber ground bevel on one side). Still for eight dollars, it is a good deal. Might even make the can opener a bit stronger (but harder to use).
