I get a ton of these every time I buy a vintage razor. I'd always wanted to try, but have been concerned they were rusty or otherwise unusable. These, however, I'd been confident to try. The shave is different! The blades are not as sharp as modern blades, but by no means are they dull. But, the shave is more thorough. I get a closer, cleaner shave than I do with modern blades. And my skin (usually rather sensitive) is not nearly as tender the next day. I hope to continue using these. There seems to have been something lost with modern blades that is working quite well for me with these -- unusually and surprisingly well, actually!
