A folding knife is one of the most practical and enduring tools ever created. Compact, versatile, and designed for everyday use, it serves everyone—from outdoor enthusiasts to tradespeople to those who simply appreciate a dependable item in their daily carry.

This guide explains exactly what a folding knife is, how it works, its history, and how to choose one that meets your needs.

What Is a Folding Knife? The Clear, Simple Definition

A folding knife is a knife with one or more blades that pivot into the handle, allowing the entire tool to be compact, safe, and portable. When closed, the blade is fully housed inside the handle to prevent accidental injury. This type of knife is also commonly known as a pocketknife or jackknife.

Unlike fixed-blade knives—which offer maximum strength for demanding tasks—a folding knife prioritizes portability, convenience, and everyday versatility, making it ideal for EDC (everyday carry).
