Rare Schick Platinium TTO Safety Razor - Made in Holland I have found little information on this rare razor. Is all plastic with the wings of the butterfly head of metal and metal gear. The shaving experience should be similar to Krona but I haven't tried it yet.
I have a Schick Platinum razor as well; I find it gives a great shave and the handle is very grippy which is another plus for this razor.
https://theshaveden.com/forums/threads/schick-krona-de-timeline.62806/ They were first introduced in Canada in 67, those models usually have a grey handle. I don't think they were sold in Canada past 67 but were sold in Europe later on and into the 70s since some exist that can be dated to after Warner Lambert bought Schick. The European ones usually have a black handle but also show up in other colors. This style razor to my knowledge was never sold in the US.
