Well, I wonder. A fellow Sly here, a couple of months back, hearing my distress over the loss of a favorite discontinued razor (a Shick injector) actually went so far as to send me, gratis!, an antique (circa 1940s) model--amber Bakelite handle, gold-plated metal, really classy object, and I think it puts current instruments to shame, if not for "perfection" of shave, certainly for aesthetics.
Well, I put in a blade (still available) and, folks, it's still giving good shaves. I'll admit that some of my shaves are at the gym with a disposable razor, but the blade in the "Golden Razor" yet provides a reasonable shave! Maybe it's magic; maybe it's luck, but I'm amazed. I sometimes wonder if we are all somewhat deluded. How so? In that shaving technology has long been perfected, and our panting after the newest implement is only a sign of the effectiveness of "the sell." Well, anyway, I'll go to my grave with a single-blade razor in my hand.
Other "old fashioned" fans out there? I will admit that I'm not so old-fashioned as to want to go to a cut-throat blade...
For head shaving I stick with the more modern headblade, but for shaving my face my main tool is a double edge razor (Red Tip SuperSpeed). I haven't found an "eternal" blade yet but I do get much closer, less irritating shaves from my double edge than anything else. I get a week or week and a half on one blade shaving pretty much every day. The other plus is that blades are quite cheap and the selection is huge online.
I've thought about going back and trying a straight edge but I haven't convinced myself to go for the investment/ learning process.
I think those are the true eternal blades though just a little upkeep and those puppies last forever!!
Ming, that's great!

You know when it comes to shaving my old noggin I prefer the HeadBlade over anything else that I have tried. But when it comes to shaving my mug, well, I prefer the old fashion DE Gillette, a badger brush, cup, Proraso shave cream and hot water. There's nothing like it.

If I actually thought that I could shave my head with my favorite 1966 Super Speeder without lopping off an ear or causing some major lacerations elsewhere, I would give it a try. I guess I'm just too chicken.
Hell, i'm all about the 20 blade new fangled razors! One stroke and your done (well, if you have a flat head).
