I picked up these vintage blades from eBay the other day and thought I would share.
Not used any of them (I probably won't even try - I want my face kept in one piece!) but I think the look of the packaging is superb
They may be fine to use,did you check the edges with a loupe or magnifying glass for rust ?....You can try one blade,if it tugs and pulls,then just keep them as a piece of history,you will know after 2 or 3 strokes.I feel the old carbon blades were actually thinner than most of todays blades.The old Gillette "blue blade" was very thin and super flexible.
