It was during WWI and the global introduction of the Swiss Army Knife that the idea of a multi-tool first gained widespread popularity. Soldiers, adventurers, and craftsmen alike were enthralled by the idea of incorporating a number of different functions into a single portable format that would take up far less space and weigh them down much less than a traditional box of tools. In the 1980s, Tim Leatherman and Steve Berliner incorporated Leatherman Tool Group, advancing to the next evolutionary step in multi-functional tooling. As time went on, the demand for greater functionality with a smaller footprint grew. Designers began to come up with ways to shrink down the classic folding tools without sacrificing their ability to do their job. And, somewhere along the line, the single-piece multi-tool was born.
There is a line between functionality and portability that classic folding multi-tools simply cannot cross. Collapsible devices can’t shrink past a certain point without forfeiting some measure of strength or performance. And that is where single-piece multi-tools shine. By incorporating the functionality of a multi-tool into the structure of the piece itself, you are not limited by moving parts or specific profiles and shapes. In fact, some of the best single-piece multi-tools have more practical features than their traditional folding counterparts while still being able to fit comfortably in your pocket, on your keychain, or even in your wallet. Here we’ve rounded up 12 of the best everyday carry, pocket-sized, one-piece multi-tools that don’t sacrifice function for form.
Evident in it’s name, the Gerber Shard almost looks more like a bit of shrapnel than a pocket tool. But don’t let the funky profile fool you.

The 2.75″ tool weighs just 0.3 ounces and comes with a limited lifetime warranty. And it is safe to bring with you on a plane, so you need not leave it at home when you travel.
Nite Ize DoohicKey

Or you can just clip it to your belt loop.
