Pretty sure it is the same head. They made a bunch of "different" razors that all had the same head and just different handles.Slightly off topic (don't want to hijack this thread, I apologize in advance), but does anyone know if the Mühle R106 has the same head as the 89? They all look alike to be honest. The R106 has a black resin handle, that may be the only difference? If It is a different head then I may trie the 89 at some point as the 106 is really quite mild.
