Enter the Herringzone
Helico MK3 has everything you could want from an executive desk toy; magnets, interlocking gears, bits that spin, striking visuals that intrigue the eye, and a gear you don't see outside of sports cars and hydroelectric dams. Precision engineered with a unique herringbone profile, Helico delivers a tonne of torque into the palm of your hand with a whopping side of satisfaction.
Upgrade your hands with a herringbone gear to interface with your local dam and be the torque of the town!
Take a Spin on the Wild Side
The classic Helico spin makes fidget spinners a thing of the past. Gently tilt the gears back and forth to feel them satisfyingly roll around your fingers and feel like your own biggest fan.
If you feel like walking on the wild side you can really get it spinning and play with the power of centrifugal force! Be warned though, spin too fast and physics will eventually take over and the weight of your Helico will overcome the power of the magnet, putting Helico on a trajectory for that small gap under your tumble dryer or your monitor screen! So much power at your fingertips, just image that eh?
Magnetic Launch!
You don’t need to sell your soul to the spin, this little fellow does all sorts. Harness kinetic energy and watch your gears repel and attract to pull off this neat old flip trick. Once mastered will you be using your force for good, or will you turn to the dark side?
Tricks, Flips, and Clicks!
Geared to keep your fingers busy, this perfect powerhouse will give you hours of fiddling formats. Toss it, spin it, flip it, bop it!
Brass Is Back
Possibly the biggest request in MetMo history since its initial release half a decade ago, the full brass Helico is back and better than ever. We might be biased, but it’s been worth the wait. Perfectly polished brass, enhanced gear profiles, and some really cool custom CNC tooling have come together to bring back the satisfying weight of a beautiful brass helical gear in the palm of your hand.
Build-A-Train
Suck it Thomas, there’s a new engine in town! Enjoy building a gear train of your own making, or get wild with your Heli-combos. Spin, drive, flick, wiggle… or create something entirely new! Can you control this unconstrained gear stack?
Opposites Attract
Check yourself before you mesh yourself. Can’t commit to one material, or just love the look of mixed metals? Combine the lightweight and soft touch nylon with the solid weight of brass, or fool the silver masses with one stainless and one titanium. No matter your set, you can combine your Helico to make all the colours of the metal rainbow. Join the club, it’s spinning time!
Precision Engineered
These gears are machined to be held! Made with precision CNC machining and finished to ensure every sharp edge and unrefined feature is perfectly made. No standard forged gears here, just rock solid, premium metal made with the love and care it(and your hands) deserves.
Magnetic Attraction
At the core of Helico are neodymium magnets encapsulated in a solid metal protective shell. This fragile magnet brings great power (and great responsibility), and are the strongest permanent magnets on planet Earth. And you can chuck them in your pocket! The laws of attraction mean you get a nice firm feedback as you pull on each gear for ultimate satisfaction. Next stop, Helico Magnetar…
Tactile Feedback
What’s a fidget without satisfaction? Pretty rubbish if you ask us. That’s why Helico delivers in a way only a herringbone gear can, and it gets you right in the feels with a smooth yet stimulating unique gear texture… Did it just get hotter in here? Use it to relieve tension in your hands with pressure based feedback, or just enjoy that sweet engineering.
A Tiny Massage
Roll a Helico in your hands and get the equivalent of a tiny centipede massage, without all the hassle of finding a trained centipede masseuse. That’s real value right there.
A Desktop Wonder
Bring your desk to life with precision engineering! Make your workplace the talk of the town and capture the imaginations of those who wander by.Whether you’re in the office, a cafe, or have a great work-from-bed setup, everyone on your video call will stare in wonder in a way that only solid metal can invoke.
Solid Metal Waterfall
Tumble the gear profiles over each other and watch the motion of the gears meshing. Lose yourself in them for a moment of peace, like watching a molten cascade at your fingertips.
It’s not everyone that can claim to hold a metal waterfall in their hands, but now you can!
Gearly Beloved
Roll Helico across the surface for a collection of satisfying sounds, and watch them snap together as they find their soulmate. Two pieces of a very satisfying puzzle becoming one. It’s enough to make this old engineer tear up.
The Thunder Dome
Each metal makes a slightly different sound, but they all share a relaxing meshing sound of precision gears that’s pretty reminiscent of a babbling brook. Close your eyes and you can almost image you’re on an alien world, sitting in the suns by a babbling stream of pure mercury. Where will your Helico take you?
Pocket Pal
Pocket your gears! The perfect size for on-the-move, gear-based shenanigans, so you can enjoy precision fidget fun wherever you go.
The Perfect Fidget Machine
The humble herringbone gear is the perfect fidget machine! Who could have predicted that? Refined over the last 5 years, this is the third and finest generation of Helico, so you can enjoy this perfectly dialled fidget that is geared to be held. With every detail carefully considered, Helico will bring endless hours of busy finger fiddling.
What’s New?
Helico MK2 has left the building, and he’s made way for this rockstar. But what’s actually different? We’ve returned to our helical roots and created a full-metal fidget that’s smooth to touch and reassuring to hold. All the best parts of the Helico you know and love, with an extra bit of MetMo magic; stronger magnets, shinier finish, and super cool to play with. With an enhanced gear profile for maximum tactility, you won’t want to put it down.
The Perfect Thumb Hole
Give your thumb a new home in these perfectly designed thumb grooves. Pick up Helico and you’ll feel right at home in the centre of this gyrating geared mechanism of magnetism.
A Machined Comfort Profile
Who would have thought solid metal could feel so good! Like it was sculpted by the gods of old, every surface is smooth to the touch for the most comfortable set of mechanical gears you will ever hold. You won’t want to put these down, and because you can take them with you everywhere you won’t have to!
Racing Stripe
Racing stripes make everything better, right? Yeah, we thought so. That’s why we upgraded this version of Helico with its very own speed stripe, guaranteed* to enhance velocity and increase your insurance premiums, and look damn good while it does.
*Well… you never can trust a car salesman…
Geometric Dance
Each Helico has a solid, reassuring weight. Like a tiny planet with a neodymium magnetic core, these two celestial gears will be locked in a geometric dance in the palm of your hand.
Gotta Catch Em All
Can’t get enough? Combine every Helico and become the Lord of Magnetism. Be careful not to drop it though, the Lord of Magnetism can still hurt their toes.
