— a compact variety of multi-tools that can be worn on a keychain, on a carabiner, in a breast pocket. Multi-tools in the form of key rings are not amazing with a variety of tools, but this option can be useful in some unforeseen situations - for example, using the built-in miniature devices, you can fix a fallen bolt on sunglasses, cut a broken nail, etc.
