What I’ve Got: The Leatherman TreadThe Tread is a wearable bracelet that is made of multi tools. When taken off and folded the bracelet itself becomes the handle for the tool. It was designed after the CEO of Leatherman was stopped at the entrance to a park because he was carrying a multi tool. It is built like a bike chain with links and has no harp edges. Each tool has a slight curve to avoid annoying the wearer. You can choose from 25 different tools but most wearers will only fit 8 links (due to wrist size). It can be worn with most watches and even some smart watches like the Moto360. The cost is $150-$200.Sources:https://www.wired.com/2015/02/leatherman-made-amazing-multi-tool-wear-wrist/http://patentmyinvention.com.au/the-fascinating-invention-that-is-the-key-ring/http://www.crookedbrains.net/2013/12/clever-and-innovative-keychain-gadgets.html
