How to Say Knife in Spanish: Complete Translation, Audio Guide, and Contexts
The standard, all-purpose Spanish translation for a fixed-blade knife is el cuchillo (masculine noun, plural: los cuchillos). This word covers the utensils sitting beside your dinner plate, the chef's knife resting on a prep station, and standard utility blades. Its etymological lineage traces directly to the Latin cultellus, the diminutive form of culter, referring to a plowshare or knife blade.
The moment a blade folds on a hinge into its handle, the term cuchillo ceases to apply. A folding pocket knife in Spanish is exclusively la navaja (feminine noun, plural: las navajas). Calling a Swiss Army knife or an everyday carry (EDC) folding blade a cuchillo sounds jarring to native speakers. Derived from the Latin novacula (a razor), navaja also doubles as the culinary noun for razor clams due to their long, hinged, bivalve shells.
When the blade leaves the kitchen table and enters tactical or combat territory, the language shifts to el puñal or la daga. A puñal specifies a straight-bladed, double-edged combat weapon or dagger intended for thrusting rather than slicing. Historically derived from puño (fist), it signifies a weapon whose grip matches the width of a closed fist. Using puñal casually for a kitchen tool sounds bizarrely theatrical, signaling a weapon of violence rather than a utensil for food preparation.
