For an open comb, it is perfect. In combination with a good razor (such as derby premium or feather), it gives a super result with just one pass. However, it requires a lot of attention and no pressure (it does not forgive). For years, I used a closed Jagger and needed multiple passes. Now, with 2 passes, it does an excellent job. It has become my main head.

Quite aggressive. It scares, without not forgiving though.
The 4 stars are purely for the feeling it creates for me, without having experience from another "open" mind...
In terms of quality, classic Muhle!
