A flipper knife is a manual folding knife that uses a fin-like tab which protrudes from the blade to open. Flippers are often carried in someone’s pocket and hence known as pocket knives.
A good size for an EDC pocket knife is around 3-4 inches long when closed.
A folding knife can be used for a number of routine tasks, such as opening packages, popping open bottles, getting out batteries, removing staples, or cutting loose threads.
