The Ultimate Micro Utility Tool

A blade like a battle axe, that’s built to last. This is the last box opener you’ll ever buy.

A new kind of box opener inspired by Japanese chisels, Edge is a handy keyring multi tool that can cut, scrape, pry, mark and chisel. Built to be robust and fast to use with no fiddling around, just pure package busting fun. 

Cut Through Everything

The hardened steel edge is designed to cut through whatever you put it to. Shaped and heat treated for maximum rigidity so it won’t damage the cutting nib, giving you years of unadulterated cutting pleasure. 

Why Edge?

We were fiddling around with making some scissors, when we made the logical move of being inspired by Japanese woodworking chisels. We figured everything is basically a chisel, right?

Who's It For?

Need to bust open a box but The Man won’t let you carry your bowie knife anymore? Edge around the rules with this compact pocket box opener, made for anyone who combats boxes with their keys, has a knife that’s too big for travel, or simply appreciates a quality engineered tool.

A Slice of History

Invented in 1870, perfected in 2025.

Inspired by the Japanese chisels (Oiire Nomi) with mentori profiles which were created by sword makers following the demise of the samurai order, and were given very unique cutting profiles so that carpenters and joiners could create intricate joints.

We have taken the iconic shape of this well sculpted tool, miniaturised it, and turned it into a powerfully robust multi-purpose box cutting warrior. 

Built to Last!

Like all our machined MetMo products, we have designed the Edge to last 200 years.

Sounds like a long time? That’s how confident we are in what we make and how we’ve designed it. 

Three different types of knife edges featured on the MetMo Edge labeled 'Chisel Edge', 'Point Breaker', and 'Downward Edge'

Double Up Your Edge

Two edges for the price of one! Our unique 90 degree double edge lets you cut in, along, around, or even head on! It also lets you scrape or slice in a much easier way than most blades, so you can tackle any job with ease.

Built For Travel

Legal to carry, this harmless little tool won’t get you in trouble with the law so you can keep it on you wherever you are, no matter what country you’re in.

With no fixed blade and its unassuming 90 degree tip, this little guy complies with all the regulations. No one will be parting your keys from the MetMo Edge. 

Attach Edge to Your Keys

These aren't any old rings, these are MetMo’s finest stainless steel flat pressed rings that let you rule over all other inferior rings. These are designed to last a lifetime and will withstand the most turbulent of pockets. They don’t bend and won’t pull apart, keeping your Edge safe on your keys for when you need it.

What’s That Edge Made Of?

The leading edge is made from 420 grade stainless steel, hardened to HRC 48-55. It has a unique 120 degree inclusive cutting angle to make it more robust than a regular box cutter, so it will keep it’s edge for longer without needing to sharpen it.

Hold Your Blade

A neodymium magnet keeps your blade stowed away and provides satisfying sliding. A clean, reliable mechanism that works every time. Magnets eh, a force as old as time.

Fastest Finger in the Wild West

Retract at speed like a frightened turtle. When you’ve got into your package and your hands are full don’t waste time folding anything away! A simple flick of the wrist and you’re done, so you can spend more time in the excitement of your freshly opened goodies, and less time juggling knives and boxes. (Although knife juggling is pretty cool).

Satisfaction Zone

Simply sliding the blade in and out gives a satisfying click with an addictive resistance, making this little tool impossible to put down! A useful slider, just what the doctor ordered.

It’s a Grower…

Just, press and extend the cutting edge to give you a small but powerful 10cm of sharpened, heat treated, hardened tool steel… too far? Maybe, but it will get the job done.

Marking Out Like a Boss

The hardened steel blade makes marking out precise and reliable. They say measure twice and cut once, but what about that marking out bit in between? 

Use the hardened tip to quickly mark any metal, wood, or leather giving you a clear and precise mark to work from. Dare to go where no pencil has gone before, so you don't make mistakes. 

Precision Scraping

Edge's unique edge profile means it can be used to scratch things off hard surfaces. Got some dried paint on a glass you need removing? Not anymore! Have a 3D print fused to your print bed? Easy peasy!

Easy Peeler

Upgrade your hand with a metallic talon.

Let’s face it, our fingernails or random keys or ballpoint pens have a limit. MetMo Edge gives you back your edge, enhanced with steel so you can tackle those pesky stickers, milk bottle lids, and once again gain access to your compressed nutrients.

Perfect Proportions

Perfectly sized to fit in your hand comfortably and small enough to tuck away. Edge sits on the edge of perfect proportions, giving you the utility of a serious tool while letting you carry it unnoticed. 

Avoid Unwanted Stabs

Safe storage of your tip. Our all-new anti-stab-yourself technology keeps the blade safely stowed away until you’re ready for action. Even an accidental ejection is nothing to worry about.

Straight to the Point

Press and cut with a dedicated forward facing blade for a precise and deliberate slice. Edge is a useful tool to have around the shop, desk, or workbench for when you just need to nip a fraction of wire or tame an out of control office plant.

Impenetrable Nuts

Gaining access to these forbidden tasty treats was all but impossible in the before times. Pry your way into everything from shy pistachios to hidden passages; nothing is off limits anymore, you’re finally free!

Prying Eyes

A tiny pry tool, Edge can get under and lift small nails, panel pins, staples, or press studs. Never be caught using a butter knife to open a paint can again.

Attach To Anything

Upgrade your EDC. Edge is small enough to neatly tuck into whatever you carry on a daily basis.

Attach to a key chain, zip, bag, or keep close to your parcel landing zone so you always have a handy cutter at your fingertips. Small and neat enough to upgrade any zip, it will sit unobtrusive giving you a satisfying zip grip, and then be on hand to quickly nip something open. Fashionable and functional.

Featherweight Champion

Coming in at 18g (0.6 Oz), Edge is designed to not add weight to your keychain so it can hide in your pocket, on your bag's zip, or tuck into your EDC kit and not be noticed. No pack horses needed for this one. 

The Travel Chisel

A wise man once said “every tool is a chisel, but every chisel isn’t a MetMo Edge.” At least I think it was that…

In any case, Edge delicately and precisely chamfers, scrapes, and shapes with the best of 'em! 

Stay On Point

Designed to be stripped down with ease so you can sharpen the business end to give your Edge it’s edge back! Keep this little cutter working for years to come.
