As a species, man has always relied on tools. The knife is one of those tools that has been around forever.
We don’t have the built-in claws for digging or defense or the teeth for eating that our wild animal friends are equipped with.
As a weapon or tool it increases production and defense levels.

Things to look for in a knife:

• Durability
• The right size for your most common tasks
• The right edge for your most common work
• A comfortable grip

There are many things to consider when purchasing a knife for use rather than collecting. Some divers prefer a blunt tip knife to reduce the risk of puncturing their dive gear. Blade steel and finish are also considerations. Smooth edge, serrated, saw-toothed and combos are all useful but each for a different task.
