Forget keeping a drawer full of screwdrivers-you can replace them all with a Tools-Key. Tools-Key is a set of keys with different kinds of tools at the tip. It has screwdrivers including slotted, Philips, hex and so on. Tools-Key helps to fix a clock or a mobile phone in our daily life. What’s more, it can be used in some emergency situations. For example, some long days’ cycling may make the bicycle screws loose, the rider can easily deal with these emergencies with the help of Tools-Key.
