Many of the Victorinox Swiss Army knives include a set of scissors. The larger (3 1/2" / 91mm) Swiss Army knives have a medium-sized pair of scissors with a maximum opening of about 1 1/8" (29mm). The total length of this tool from handle to tip is about 2 5/8" (67mm).
Since 1991, Victorinox scissors have been attached with a rivet at their pivot, rather than a screw. Although it is not adjustable, the rivet will never come loose, and it generally keeps the scissors in great working order for many years.
All of the Victorinox scissors include a small return spring, which makes snipping go much more smoothly. Because the spring is attached directly to the scissors handle, you can use the scissors in any position. The blade locks into place when in the fully-open position, but you can also use the scissors when the blade is only partly extended.
The Victorinox scissors don't need any specific maintenance, although you might want to put a drop of mineral oil at the pivot point about once a year.
