Metmo Fractal Vice 82mm Stainless Steel Review: A Fractal Vice That Wraps Around Anything

Introduction

Metmo has released the Fractal Vice, a new take on the workbench clamp that replaces the familiar two parallel jaws with an eight-point system built to wrap around whatever you are holding. It comes in four versions: stainless steel or black steel, in either 82 mm or 32 mm jaw sizes. The 82 mm stainless steel version tested here is currently listed at about $359 on the Metmo site, and it is the most overbuilt and intricately machined of the range.

If you have spent years working around conventional vises, the pitch is simple: this one grabs irregular, soft, or fragile objects without squishing or dropping them, and it does it with an obvious level of engineering care.

What Makes a Fractal Vice Different

A conventional vise holds an object between two flat, parallel faces. The Fractal Vice works differently. A large outer jaw slides to distribute force evenly between two pieces, each of which can swing independently and distribute force again across its own contact points. Cinch it down and the clamping force is spread over eight points that do not need to line up the way parallel jaws do.

That geometry is what makes it genuinely useful. You can hold soft objects, fragile items, and odd shapes that would defeat a standard vise. Clamped around a rounded, angular chisel holder, the jaws wrap and snug down instead of crushing the edges. It has been used on sunglasses, electrical components, and all sorts of odd-shaped odds and ends, and you can feel the even pressure all the way around an object when you tighten it, like the contours folding around it rather than pinching from two sides.

Swappable Jaws and Mounting Options

The jaw inserts pop out quickly by removing a screw, so you can reconfigure the vice for the job at hand. Metmo offers several jaw options beyond the included stainless steel set:

• Brass jaws, sold for about $60 a set or roughly $15 apiece, with excellent workmanship
• Nylon jaws, a lightweight option at about $20 per extra set
• Stainless steel jaws with a silicone plate, about $55

You can mix and match these in the same vice, which makes setup easy when one job needs a softer touch and the next needs something firmer.

Mounting is similarly thought out. Rather than clamping the vice body directly, it can be secured to Metmo’s quick-release plate ($65), which then attaches to a bench or another plate. The vice ships with a rubber plate covering a mounting hole underneath; pop that out and you can connect it to the quick-release plate with a twist, and the fit is rock solid thanks to tight machining.

Build Quality

This is a dense, heavy piece of hardware, and the machining is the standout. Every sliding and swinging surface moves smoothly, the jaw attachment secures with a satisfying twist, and the whole assembly has the silky, precise feel you want from a tool you will adjust hundreds of times. Among the fractal vises currently available at this size, this is arguably the premier offering: strong, overbuilt, and beautifully finished.

Who Should Buy the Metmo Fractal Vice

This is a tool for hobbyists and professionals who regularly clamp irregularly shaped, delicate, or soft objects that a standard vise cannot hold safely. Desktop users will appreciate that it mounts cleanly to a quick-release plate and can sit in a utility vise as well. If your work only ever involves square stock and parallel faces, a conventional vise still does the job for less money, but if you have ever crushed a part or wrestled with a weird shape in flat jaws, the Fractal Vice solves a real problem.

Conclusion

The Metmo Fractal Vice 82mm Stainless Steel is a beautifully machined, genuinely different kind of vise, and it is available to order now. With four size and finish combinations starting well below the stainless 82 mm price, there is a version for most workspaces, and the swappable jaw system keeps it flexible across tasks. For anyone clamping odd shapes, soft materials, or fragile parts, it is a strong contender for the most interesting workshop tool of the year.
