Even if scaling rock faces is not your thing, you probably know how handy a carabiner keychain can be.

These days key chains are one of the hottest promotional items available and there are many reasons for that. Carabiner keychains are always useful and easy to use. They are now available in seemingly every color under the sun and laser engraving techniques mean that your promotional message is easy to add in a variety of colors and fonts. And, the best news of all, laser-engraved eye-catching keychains are available for much less than a dollar a piece.

No matter how high quality a keychain you choose though, don't ever think about using them with ropes on a mountain - for climbing you should only ever use a carabiner that has been specifically manufactured for climbing and that is fit for your purpose. If in doubt, ask at your nearest dealer of mountain hardware.
