Ooh, now thats a razor! I have a Merkur Futura myself. But that sure looks nice with exactly the same adjustable feature. These old school razors are FAR better then the modern toy multiblade gimmick excuses for razors.....
I have seen those Merkur Futuras for sale and they look very nice, I kind of like the older stuff though and got the Gillette for crimbo of my lovely wife.
Its got to be said that I wouldn't complain of it were more aggressive though. I usually shave my chin with it on the 9 setting (the most aggressive setting) and the 5 setting does my head nicely.
Would be nice if the 9 setting was a bit more aggressive cos I also have another Gillette which is non adjustable but takes a fair bite. Its not one to use after a few days without a shave but its good each day.
I've a similar as part of a 1950's travel set including brush, I'll take some pictures when I eventually return home. The only time I use it is when abroad on holiday, its a nice thing to use.
That's kind of why I like mine, its just a nice piece to use and to be honest I find it a better shave than the twenty blade modern plasticky thing with lubristrip I now haven't used since crimbo. Not hard to get the hang of either, no significant cuts when starting out with it.
Seriously, modern razors are NOT better, not nicer to use than older ones. They just have more advertising.
