How should diving knives be primarily viewed in terms of their purpose?

Diving knives should primarily be viewed as a multi-purpose tool because they serve several important functions that enhance a diver's safety and efficiency underwater. While they can be used to cut through entanglements, such as fishing line or kelp, their design often accommodates other uses, like prying or scraping. This versatility is essential in a diving environment, where unexpected situations can arise.

Viewing a diving knife solely as an accessory or decoration undermines its practical applications, and although safety is a significant aspect of its use, limiting its purpose to safety only overlooks the other functional roles it can play for divers.
