Unfortunately, unfortunately, the blades are not commercially more to get, so I look forward all the more that there is Amazon. Have now excited more than 25 years in use and am still this kind of blade. Of necessity, I crossed over to newer 'blade models "and find they are not nearly as good as my old Gillette. I think there is always with new blade systems, usually as plastic, made a lot of money, blade systems, which no one really needs.
Hopefully there are those blades that are cost effective and very sharp, very long time !!
