The razor head 2 Merkurs is extra: precise, soft, comfortable, well-slice ...
The handle of the 23C is also perfect: excellent grip, and long enough, which provides very good maneuverability (I blamed that of 34C to be too short ... but it's personal, it depends on the hands and faces).
The weight is perfect, neither too light nor too heavy.
In sum, the Merkur 23C is my favorite razor.
