Blades

EDC hardware brand Orioner says this new folding knife is the smallest piece of kit it's ever made: it's about half the length of your pinky. It's got a beautiful titanium frame and can also open bottles in a pinch.

Hacksmith Industries has focused its engineering chops into creating a lightweight titanium multi-tool that looks like a compact pocket knife, but actually packs up to 21 features. Oh, and its blade is strong enough to cut a Swiss Army knife in half.

Makers, tinkerers, modelers and crafters looking for an edge that smoothly cuts through a range of materials like they're all butter might find the NeoBlade of interest – which is claimed to be the world's most compact wireless ultrasonic cutter.

While a small blade and other simple tools do come in handy at times, why carry around a separate multitool when you're already using a keychain? That's the thinking behind the all-in-one KeySnap carabiner, which is currently on Kickstarter.

Kickstarter makers certainly seem to be obsessed with putting as much functionality in as small a space as possible. Case in point: the new Slash microblade, that promises to give you super sharp cutting power in a keychain capsule.

In 1964, the Buck Knives company marketed its 110 Folding Hunter knife, which changed the knife-making industry forever by introducing a revolutionary folding blade that locked into place so strongly it performed like a fixed-blade sheath knife.

GE is looking to a new generation of carbon-fiber composites to make the fan blades for its GE9X jet engine. That engine is being developed for the Boeing 777X passenger airplanes set to enter service in 2020 and the new blades promise to provide larger, lighter engines with greater fuel efficiency.

The Cardsharp 2 improves upon the original Cardsharp credit card knife.
