I learn that there are thus 2 types of blades. I understand better because when I told to have been disappointed by Iridium, certain members of forum, here in France told me not to understand. I bought the version in dark blue (without the registration in the back), and openlyit is far from what I read.
Maybe the others ones are the "authentic " Iridiums.
