My tool is a cross between a carabiner and a keychain. It will allow astronauts to connect things such as tools to a belt. As a result, astronauts will have their tools by their side and close at hand. For example, if their tools had a "holepunch" through them, one keychain could connect to the tool. Another keychain would attach to the toolbelt. Because the keychains can attach and detach, astronauts can easily switch between tools they are using as well as keep their tools close.
