I grabbed a ton of these blades at an estate sale today. Being that these are old blades will these rust a razor if left in after use? How do these compare to persona UK version blades? Are these old or am I assuming wrong?
Those blades are stainless. I am not sure how old they are, but you might be able to find some clues on the packaging. The older Wilkinson blades were made in the UK. Newer ones are made in Germany, and have similar packaging.
The "New Chromium Edge" came out around 1970. They are the famous Light Brigade blades, named after the painting on the packaging. Those are thought by some to be the best blade of all and/or the best Wilkinson Blade........ Congratulations!!!
