Le Coq Palmer
Big Adjuster Knob

This is the Version with the over sized adjustment knob.
Its a zamak razor as can be seen from the head and the raized text under the head. This one is going to have to be treated carefully.
The adjustability is the same on all the versions - it has the strong centre spring that pushes the blade against the topcap.
There are alignment grooves on the topcap and base plate.
They also don't have lather grooves so need more rinsing than other razors.

How does it shave?
I haven't used it, so can't really say.
That said - I suspect that this will be like the others which I find to be very mild shavers and as a result open them up pretty wide. Once they are opened beyond a full turn, they become pretty effecient shavers.
