Keychain tools: carry your tools everywhere
You always carry your keys, so why not add a keychain tool so you always have it close? For example, a bottle opener, a screwdriver, a pry bar or even all those things in one tool! So you always have a handy little tool at hand to fix a loose door handle, pry open packaging or open a bottle of beer.
How to choose the best keychain tool
Keychain tools come in different shapes and sizes. There are bigger tools and smaller tools that won't stand out from your bunch of keys. When choosing a keychain tool, consider what size you would prefer. Do you usually keep your keys in your pocket? You might prefer a more compact tool. Or do you throw your keys in your bag, so compactness won't necessarily be a priority for you?
That leaves the question of which material you would prefer. Steel is strong, but heavy. Aluminium, on the other hand, is lightweight but less strong. Lastly, titanium is lightweight and very strong, but also more costly.
