A good tradesman will care for his tools. After all, they are very much a part of his livelihood and they can also convey a lot about him. Ask yourself, who would you trust most: a tradesman with cheap tools in a carrier bag or one with lovingly cared-for and arranged tools in a toolbox? It makes a difference, doesn’t it?

Of course, tradesmen will find ways of adapting and even ‘hacking’ tools for jobs where no manufactured tool exists. But some take it to the extreme, like this wonderfully inventive tool enthusiast who turned a simple house key into a mini-toolbox you can keep in your pocket. The uses noted on the picture are as follows.

Multi key

1. Drill
2. Wood saw
3. Bottle opener
4. Rope cutter
5. Screwdriver
6. Hexagonal key (eg for Phillips screwdriver plug-ins)
7. Knife sharpener
8. Wire cutter
9. Nail remover
10. Nail file

For those who like their multi-tools to be a little more refined, hi-tech and handy around the office: how about a paperclip/USB drive/ruler?
