The Victorinox Cavalier is a slim 74-mm knife with just three tools, accordingly to the SAKWiki, based on model Prince (same tools set, but scales are from stainless steel). I suppose that lot of variation of this model (Cavalier) should exists with different scales and combination of presence \ absence of toothpick, tweezers and key-ring.
This one has a key-ring, but without toothpick and tweezers; another variation with smooth Alox scales I already have in my collection; both aren’t present in SAKWiki.
Interesting fact: name Cavalier also was used for another knife in 58-mm format. Ah, this eternal problem with the scarcity of accessible words, if you know what I mean…
