canivete

a small single-edged knife; a pocketknife

Inherited from Old Spanish canyuete, canivete (1291), either from Old Occitan and Old Catalan canivet, ganivet (“small knife”) (Catalan ganivet), both from Vulgar Latin *cnīfittus (“small knife”), from Vulgar Latin *cnīfus (“knife”), from Frankish *knīf (“knife”), ultimately from Proto-Indo-European *gneybʰ- (“to pinch”).
