What are layers on a Swiss army knife?

Layers on a Swiss Army knife refer to the different tiers or segments of tools and functions that are stacked or housed within the knife's handle. Each layer typically contains various tools such as blades, screwdrivers, can openers, and other implements, allowing for a compact and versatile design. The number of layers can vary among models, with some featuring just a few tools while others may have numerous layers equipped with a wide array of functionalities. This multi-layer design enhances portability and usability, making Swiss Army knives popular for outdoor activities and everyday tasks.
