Couteau suisse vs. canif

When discussing pocket knives in the French language, 'couteau suisse' and 'canif' are two terms that may come up. While both serve a purpose as handy cutting tools, their specifics and connotations differ.

Couteau suisse

A Swiss Army knife ('couteau suisse') is commonly understood to be a multi-function pocket knife with various tools such as blades, screwdrivers, can openers, scissors and many others, all folding into the handle of the knife. It's known worldwide for its versatility and practicality.
Peux-tu me passer ton couteau suisse ? J'ai besoin de son tournevis pour réparer mes lunettes.
(Could you pass me your Swiss Army knife? I need its screwdriver to fix my glasses.)
Un couteau suisse est un choix populaire parmi les campeurs pour sa multitude d'outils pratiques en un seul instrument.
(A Swiss Army knife is a popular choice among campers for its multitude of practical tools in one instrument.)

Canif

A 'canif' refers to a simple pocketknife or small folding knife typically used for tasks such as cutting paper, carving wood, or opening envelopes. It doesn't usually come with additional tools like the Swiss Army Knife.
J'utilise un canif pour tailler le crayon lorsque je dessine en plein air.
(I use a penknife to sharpen the pencil when I draw outdoors.)
Le vieux pêcheur gardait toujours un canif dans sa poche pour couper la ligne si nécessaire.
(The old fisherman always kept a penknife in his pocket to cut the line if necessary.)

Summary

In summary, while both the 'couteau suisse' and the 'canif' refer to knives that are useful and compact, the 'couteau suisse' is specifically a Swiss Army knife revered for its multiple tools integrated into one device. The 'canif', on the other hand, is generally considered to be a basic penknife with primarily one blade and lacks the additional features found in a 'couteau suisse'. Each has its own context of use, where one may be preferred over the other depending on the simplicity or complexity of the task at hand.
