Of course the saga continues. A few years ago, PPI discontinued producing Polsilver blades. I still have a few of them, but I find them to be mid-sharp, sort of similar to Gillette Platinum and Gillette branded Wilkinson Sword blades made in India. While such blades are wonderful for many shavers, they were not really sharp enough for my tough beard. Availability of Polsilver blades is limited as inventories have diminished and prices have risen..
A few years ago, the PPI plant started producing Wizamet branded blades that lacked any reference to Polsilver. I did not use these blades until recently but found them to be very sharp and very smooth. They are not as sharp as Feather and BIC Chrome Platinum blades, but nearly so. I liked them so much that I purchased 100 blades, even though I already have enough blades to last for many years. If you like sharper blades, you might like the PPI Wizamets.
Earlier this year Gillette announced that they would discontinue producing blades in Russia for export. The blade production is being relocated to India and China. I suspect some blades might even be made in other countries where Gillette has production facilities. AFAIK, the only new production blades that have been seen in the market are Astra SP blades from India and King C Gillette blades produced in China. However, there are still Russian PPI blades in the supply chain. Only time will tell if all the PPI brands will be relocated or if some will simply die out.
