I recently purchased a strange looking razor on eBay. This appeared to be something that
@efsk would get, however it took a regular DE blade.
The razor arrived today and it is an interesting design. The razor manufacturer is Archdale and it is an adjustable angle DE razor. I can be set up as a regular razor with the head perpendicular to the handle, at diagonal angles to the handle (from mild like a Mulcuto to extreme like a Neo Ras), and all the way down to parallel like a Japanese kamisori or a Razorine. It also has the ability to angle the head while perpendicular to the handle.
There is a long shaft that is threaded on the bottom that locks the head at the angle you would want. The top cap is threaded and so the screw post is attached to the pivot joint. When screwing the top cap to the razor, there is a long pin on one side and a short pin on the other and so you can only assemble it one way. I also found that when fully tightened, the head assembly is crooked from the angle joint and so it needs to be loosened a little to be able to use it at an angle.
An unusual feature of this razor is that it has differential shaving sides. This in itself is not unusual as many razors have differential sides for shaving. What is unusual is that the base and cap are shaped like a wave and so the edge of the blade exits at a different angle for each side.
The side that is marked “Once over shave” has the blade angled downward toward the guard like a regular razor. The side that is marker “Close shave” has the blade exit at an angle that is straight or maybe even upward. At first glance, this looks very dangerous to shave with, however having the head pivot downwards while perpendicular to the handle might allow for an angle closer to that of a straight razor.
I spent the whole afternoon getting to understand this razor and clean it up a bit. Tomorrow I will give my shave report.
