I posed this question in another thread but received no response. The Caly 3 is such a refined design. In so many small ways you can see the thought that went into this knife over its generations. What I cannot figure out is why it has such a bulbous, protruding pivot pin. On a knife this thin it is quite noticeable, not troublesome, but definitely out of place (to my eye at least). I'm sure there is a reason, anyone know what it is?
