Chapter 1: Understanding Multifunction Tools & Knives

The Sum of Its Parts

At its most basic, a multifunction tool is any implement that consolidates several discrete functions into a single, portable package. The folding multi-tool, usually with a pair of pliers as its centerpiece, is the most common and recognized form. But the category is broader.

The value proposition of these tools is not just fewer items to carry, but fewer items to lose, maintain, and manage. This efficiency is why they have moved from a novelty to a standard piece of kit for many trades.

How a Folding Multi-Tool Works

The mechanics are a triumph of space utilization. The core is a pair of pliers that fold into the
