Material: Stainless steel resists wear and nicks. It will look as beautiful years from now as it does today.
Design: The new roller further reduces wear, while adding smoothness to the opening and closing action. The roller engages in a track, ensuring precise alignment.
Ergonomics: The restyled lever is easier to handle while opening and closing.
Geometry: The closing action is more uniform, closing with the same feel and requiring less adjustment between thicker and thinner parts of the neck.
