My brother Brian and I have gotten into this vintage shaving mood. He and I both have recently bought old style double edged (DE) razors (mine just arrived today). We want to learn how to shave properly with DE with the hope that we can switch to a straight razor without cutting our own throats.
DE blades also cost a lot less, last longer, and are more renewable/recyclable than the current throw away razors. And they should give cleaner shaves than an electric. And it's kinda meditative to clear your mind, press a sharp piece of steel to your face, and proceed to shave off that morning stubble.
This is a picture of the razor I bought from Ebay. $10 with shipping, I think it was made in the 1940's.
