The headline says it all. I like safety razors with handles that screw/thread into the cap, passing through a hole in the plate. There's just something about them. More minimalist, I guess. It seems like a simpler way to attach the pieces of a razor together, with fewer parts that can break off or rust. And, most of these type of razors seem to be quite solid and heavy, and appear (to me) to predate the razors that attach the more usual way. However, I haven't noticed many of these type of razors around. Darwins are the most well known, of course, and obviously the most "high end". On a more humble level, there's the (plastic?, bakelite?) Contact Propeller razor. In any event, here's my contribution to the search: Two Empire Razors from Australia (Gumtree acquisitions). I'd be really pleased to see if anyone else has come across any other brands.
