Titanium

So yes, there are indeed a ton of multi-tools on Kickstarter and Indiegogo right now. One of the latest distinguishes itself, however, by including tools such as an "everlasting" pencil and a ratcheting screwdriver.

Mythos, the British bike components manufacturer that previously brought us a £500 3D-printed bar stem, is at it again. This time, the company is offering a £1,250 (about US$1,508) 3D-printed titanium handlebar.

Engineers have developed a new 3D-printed titanium alloy with a unique microstructure that makes it ultra-strong. Not only is it stronger than other forms of titanium, but it has the highest strength-to-weight ratio of any 3D-printed metal ever made.

Sending materials into space is expensive, so the more astronauts can make on-site, the better. Engineers have now demonstrated how crushed Martian rock could be mixed with a titanium alloy to make 3D-printable building materials.

Multi-tools definitely are useful, but not everyone likes jamming the things down into a pocket. That's not a problem with the titanium-bodied K-Smart, since it doubles as a clip-on chainring which can be quickly removed as needed.

UK mobility startup Evari is heading to Eurobike in Frankfurt, Germany, later this month with a smooth-looking premium ride called the 856, an ebike rocking a monocoque carbon fiber frame, a Bosch Performance Line drive and titanium components.

Thanks to the current ebike gold rush, we're seeing many models coming to market that are basically cheap bicycles with motors. Such is not the case with the OL+EM, however, which features a custom-fit titanium frame and some top-end components.

In recent years, we've seen an increasing number of multi-tools that incorporate a carabiner main body. One of the latest is the Octo, which features a fold-out magnetic bit driver that doubles as an automotive window glass breaker.

Brompton has reworked its iconic folding bike design for its lightest model ever. Thanks to the T Line's titanium frame, a new drivetrain and carbon fiber components, the finished bike comes in some 37 percent lighter than an original all-steel ride.

It's common for outdoorsy types to carry both a compact flashlight and a lighter, in the form of two separate devices. The Hunt 4.0 combines them in one titanium-bodied unit, along with a pry bar.

If you tried carrying a wrench, bit driver, knife, crowbar and bottle opener with you at all times, your pockets would get pretty full. That's where the Pichi X2 multi-tool comes in, as it combines all five functions in one device.

In 2015 we first heard about the Helix, a compact-folding, lightweight titanium bike. One successful Kickstarter campaign later, it has now finally entered commercial-scale production – and it's not made entirely like other titanium bikes.
