This is like the ultimate Swiss Army Knife of keys. If you’re not the jangly keyring sort, or the carabiner through belt loop sort (thank goodness), or the key purse sort (dad!), now you have the option to be the KEYSMART sort. No more holes in trousers (caused by keys, at least) or scratches on laptops. You can organise and customise like the Keymaker in Matrix Reloaded never could.
