I would suggest neither of those are current production. This is the current logo design on their global website, which is also found on all the Dorco blades I purchased in the last year.However, there must also be a difference in the material used compared to the razor blades of a couple of years ago, but I do not understand what.
The one on the left in the photo is a two-year-old razor blade and looks very different from the current production as well.
