Digby Antiques (Wiltshire) has dated this Silver Cigar Cutter Penknife to the 1960s.

The mechanism is quite stiff and show very little signs of use, the cutter is opened by pressing down on the small lever on the side, this is very stiff and I have found it quite difficult to operate, but the cigar cutter opens well.
