I have a theory ...
SuperMax have had a major brand revamp, just that we didn't notice because I think they've streamlined it largely in the Indian market which we only get a glimpse of in the west via certain eBay vendors.
Looking at their global site, they're down to just two double edge blades: the (new) SuperMax Blue Diamond Platinum and what appears to be an old(er) design SuperMax Super Stainless (in green pack with three yellow lines). Gone are the old SuperMax Blue Diamond Titanium, gone are the old SuperMax Platinum Plus and the Stainless, gone is the (rather good) SuperMax Super Platinum (white pack with three blue lines).
Now, over on what I think is the Indian side, there's SuperMax, Vidyut and Zorrik branding ...
There is a Super Platinum in all three lines ("With new sputtered technology ...") which I have tried from the Vidyut line so far and it put me very much in mind of the discontinued SuperMax Super Platinum mentioned above. In the SuperMax line, it's the Blue Diamond (listed as a Super Platinum "I like the way it feels ..."). I'll have a better idea once I've tried from the other brand lines, but I think that's the same blade but "with new sputtered technology" as they say.
There is also a Titanium in the SuperMax and Zorrik lines both citing "Swedish Steel" and sounding a lot like a "new and improved" SuperMax Blue Diamond Titanium. Meanwhile in the Vidyut line, there's also a Platinum Plus (again "New Improved").
What else is there?
Zorrik Talvar, a chrome blade which could be the old Supreme single/saloon blade. There's also a simple Super Stainless in the Zorrik line. It does look like the existing blue pack Vidyut/SuperMax Super Stainless and the legacy Vidyut/SuperMax Stainless (Red/Yellow pack) & Vidyut/SuperMax Platinum (White/Blue pack) are still widely available across the sub-continent as well as very popular in Indian supermarkets worldwide.
I think I can point to any/all of these (new?) blades as their old SuperMax and Vidyut/SuperMax counterparts but they're all citing "new and improved" and have other quote lines like "new sputtered technology ..." and "new robotised technology ..."
It's a revamp and a rebrand. It's perhaps less confusing when you drop the old lines and see all these extras as a new generation.
Blimey! I should get out more
