METMO has a talent for taking the visual drama of engineering and translating it into objects people want to touch, turn, and carry. The Grip reimagined the adjustable wrench after nearly 130 years of design stagnation. The Pen turned a dual-thread screw mechanism from 1892 into a fidget object. The Fractal Vise made a complex machinist’s tool into something people keep on their desks purely for the pleasure of operating it. Each time, the Leeds-based team finds a mechanical idea that was ahead of its moment, and rebuilds it with the precision and material quality the original never had.
Helico follows that lineage, but takes a noticeably different turn. Where most METMO products carry a clear functional premise, this one leads with pure tactile indulgence, arriving as a compact magnetic form that looks carved from the DNA of helical gears. Every surface seems designed to catch the thumb, reflect light, and reward movement. It comes in four material variants, brass, stainless steel, Grade 5 titanium, and nylon, with each one shifting the personality of the object in a way that feels deliberate rather than cosmetic.

Two cylindrical modules stack vertically, held together by nickel-coated neodymium magnets sandwiched between each section. The magnets are strong enough to keep the stack stable in your hand but calibrated to let you pull sections apart, rotate them, and snap them back together without fighting the object. That separation-and-reconnection loop is where the fidget factor lives, and it turns out to be deeply satisfying in a way that is genuinely hard to articulate. The snap of two sections realigning carries a small but precise reward signal, the kind that makes you do it again immediately. METMO has effectively built a tactile feedback machine disguised as a gear stack.
The angled herringbone grooves channel the thumb naturally while turning every surface into a structure that catches and shifts light as the object rotates. Rolling Helico between your fingers produces a continuous tactile rhythm, a frequency of peaks and valleys that keeps your hands occupied without demanding any conscious attention. The geometry is more considered than it first looks, with the pitch and depth of each tooth calibrated to feel satisfying rather than sharp or aggressive. On the inside of each module, a smooth machined cup creates a deliberate contrast, a quiet surface that makes the exterior texture feel even more intentional by comparison. It is the kind of detail that shows up in product photos but only fully registers when you are holding the thing.
Brass is the version that photographs best and probably sells the story hardest. High tensile HTB1 brass carries real weight, that dense satisfying heft that makes an object feel purposeful rather than precious. It also ages, picking up patina in the spots where your fingers land most often, building a record of use that the steel and titanium versions simply do not. Stainless steel, machined from 316 grade stock, takes the opposite approach: clean, cool to the touch, corrosion-resistant, and visually neutral in a way that lets the geometry do all the talking. Between the two, I would call stainless the everyday carry option and brass the collector’s piece.
Grade 5 titanium is lighter than either brass or stainless, and that shift in weight changes the feel of the object more than you might expect. The same herringbone geometry that feels dense and substantial in brass becomes almost nimble in titanium, sitting in the pocket without any real presence until you reach for it. Titanium also carries those aerospace-adjacent associations that the EDC world never quite gets tired of, and METMO leans into that without apologizing for it. Nylon, specifically PA16, is the outlier of the four, lighter still and matte where everything else is reflective, making Helico feel more casual and approachable. It is the version for people who want the tactile experience on a budget, or who simply prefer their desk objects without the weight class.
Every instinct in the EDC market seems to demand that small objects justify their existence with a list of functions, bottle opener here, hex bit storage there, ruler along the side. Helico skips all of that entirely, and the confidence of that decision is a big part of what makes it interesting. There is no hidden tool, no secondary feature, no apologetic add-on to make the price feel earned. What you are paying for is the machining quality, the material, the magnet calibration, and the sensory experience of an object designed from the ground up to be handled. That kind of object is rare in a product category that too often dresses fidget toys as tools and tools as fidget toys.
The four material variants give Helico a range that most desk objects cannot claim, each one tuned differently enough to appeal to a genuinely different buyer. Brass for the collector who wants something that ages with them, titanium for the EDC enthusiast building a curated pocket, stainless for the person who wants precision without warmth, and nylon for everyone who just wants to fidget without overthinking it. METMO has always been good at making objects that look like they belong in a museum and work like they belong in a toolbox, and Helico sits at an interesting point on that spectrum, leaning harder toward the former than anything the studio has made before. Whether that signals a deliberate pivot or just a smart product line expansion is worth watching. Either way, it would be very easy to put one on your desk and never move it again.
