Vintage blades for vintage shaves! The luxury of pairing a vintage blade with a vintage razor is one that won't befall many, and will always be remain an experience to be cherished and savored. Although most vintage blades will not be as good as modern blades, they offer something more important, namely nostalgia and exclusivity, not to mention bragging rights with friends and family! Do keep in mind that razor blades prior to 1960 were mostly carbon steel, and today's blades are mostly stainless steel, stainless is more resistant to corrosion and wear, and lasts much longer. Expect less shaves with your vintage blade and dry it immediately after use to get the maximum amount of uses out of it.
Silver start blades seem to have been the 'Feather' blade in the era just after the second world war, They were produced and marketed from 1948 to 1953.
In that post-war era, they were advertised as being so sharp and smooth that you'd not know a blade was loaded, as with all blades, this was not necessarily true, or at least not for all users, much as with modern blades.
They were an early stainless steel blade, uncoated, from ASR. Duridium was a trade name for 404B Stainless. Two blades in this unopened pack.
Note* For obvious reasons vintage razor blades are a lot harder (and more expensive) to find than vintage razors, and such items will come and go on our website, grab more than one pack if you could, one to try out and one for your collection, soon enough they may not be available at all!
