The world’s largest knife is the “Jungle King 1” machete made by the Colombian company, Empresas Iasa. It measures approximately 32 feet (9.67 meters) in length and weighs over 440 pounds (200 kilograms). The machete was created in 2005 as part of a promotional campaign for the company’s line of outdoor tools and equipment.

The Jungle King 1 features a large, curved blade made of stainless steel, along with a sturdy wooden handle. It was designed for use in dense jungle environments and can be used for a variety of tasks, such as cutting through thick vegetation, clearing paths, and preparing food.

While the Jungle King 1 is officially recognized as the world’s largest knife, it is not a practical tool for everyday use. Instead, it serves as a symbol of the company’s commitment to producing high-quality outdoor equipment, and as a unique and eye-catching piece of promotional material.
