637. Picknicker (91mm)
The Victorinox Picknicker – old and vintage 91-mm model which is similar to more popular Camper, but with serrated blade instead of regular blade and pruning blade instead of small blade.
From SAKWiki: In Germany this knife initially was known as Campingmesser.
Interesting (and confusing) fact: in old Victorinox catalogs (see pictures below) under Picknicker name were listed two models – with and without saw.
