The Pocket Toolbox, Edited Down.
Everyday carry can become a contest to see how many objects a person can attach to a pocket before the pocket files a complaint. PICHI takes a more interesting position: carry less, make each piece earn its space, and make the objects good enough that you actually want them with you.
By Dr. Rob Urban · On titanium, replaceable edges, modularity and why restraint may be the hardest feature to engineer
A tiny design problem with nowhere to hide
Pocket tools are interesting because every unnecessary millimeter eventually becomes your problem.
I have always liked objects that are forced to justify themselves.
A kitchen appliance can occupy half a counter and still insist it needs another attachment. A vehicle can hide questionable engineering under carpeting, plastic trim and several thousand pounds of other vehicle. A pocket tool has no such luxury. Make it too large, too heavy, too awkward or too specialized and the owner performs the harshest product review imaginable: he leaves it at home.
That is the real design brief behind everyday carry.
The term EDC can describe everything from keys and a wallet to a carefully assembled ecosystem of knives, lights, pens, pry bars, drivers and small tools. At its best, though, everyday carry is not about accumulating miniature equipment. It is about deciding which capabilities deserve permanent residence on your person.
PICHI Design is interesting to me because its best products feel edited rather than stuffed. The G9 utility knife is a tiny titanium body built around a replaceable blade. The X2 family approaches the multitool as a flat piece of pocket machinery rather than a folding toolbox. NODE-1 turns the humble capsule into a modular platform that can become storage, a bit driver or a lighter.
Different objects, same question: how much useful capability can disappear into a pocket without making the pocket worse?
Designed from the problem outward
PICHI's origin story begins outside, not in a conference room.
PICHI says the people behind the company are industrial designers, mechanical engineers and product engineers based in Western Canada. The team describes roughly 15 years of experience in mechanical design and manufacturing before the EDC idea itself took shape.
According to the company, the turning point came in 2020 while hiking and cycling around the Rockies. The gear they carried did not provide the functionality they wanted, so they began designing their own.
I like that story because EDC is unusually sensitive to lived experience. You can render a beautiful titanium object on a screen. You cannot render the irritation of carrying an extra 40 grams all day. You discover that by carrying it.
- Before PICHI
The team says its industrial, mechanical and product-design experience reaches back roughly 15 years.
- 2020
PICHI traces its EDC direction to outdoor use in the Canadian Rockies and dissatisfaction with the functionality of the gear the team was carrying.
- X2 era
PICHI says the original X2 spent 11 months in design, building and testing, with user research shaping the functions selected for the tool.
- G9
The G9 reduces the cutting problem to an 80 mm CNC-machined body with a replaceable utility blade and one-handed slide mechanism.
- NODE-1
The company extends its minimalist approach into a modular capsule that can change roles rather than forcing the owner to carry separate fixed-purpose containers.
The design philosophy
EDC has an unusual enemy: feature creep.
A multitool can always contain one more thing. Add scissors. Add a saw. Add a file. Add three screwdrivers, two openers and a mysterious hook nobody understands until a camping trip six years later.
The problem is that every addition has a cost in thickness, mass, complexity or accessibility. Eventually the object becomes excellent at winning specification comparisons and less excellent at living unnoticed in a pocket.
PICHI's stated philosophy is “simple but powerful.” That phrase can easily become marketing wallpaper, but the physical products give it some credibility. The G9 does not pretend to be a survival knife. It cuts. The X2 approach concentrates several common utility functions into a small body. NODE-1 does not permanently commit the capsule to one use. It lets the owner configure the use.
There is a product-design lesson hiding here that applies far beyond EDC: removing a feature can be an act of engineering.
Every capability that survives the edit has to become easier to reach, easier to understand or easier to carry than it would have been in a more crowded design.
Cut
A replaceable edge means the body can be the durable object while the consumable cutting surface remains inexpensive and easy to renew.
Fix
A compact multitool makes a small set of common mechanical interventions available without asking the owner to carry full-size tools.
Adapt
A modular capsule changes function by changing components, which is a different strategy from permanently building every possible function into one object.
G9 titanium utility knife
The smartest part of a premium knife may be the cheap blade.
The G9 is a lovely little contradiction. PICHI machines the body from Grade 5 titanium, a material chosen for strength, low weight and corrosion resistance, then puts an ordinary replaceable utility blade at the business end.
That is exactly the right relationship.
Cutting edges are consumables. They encounter cardboard, adhesive, plastic strapping, tape, grit and all the other indignities of ordinary life. A beautiful permanent blade invites the owner to preserve it. A replaceable blade invites the owner to use it.
PICHI lists the titanium G9 at 80 mm long, 16 mm wide and 9 mm thick, with a weight of 55 grams. Its CNC-machined Grade 5 titanium frame uses a one-handed sliding mechanism, and the blade can be changed without tools.
The result is not a miniature chef's knife or a tactical fantasy. It is an extremely refined answer to the sentence, “I need to cut this.”
That specificity is why I like it.
Replace the edge, keep the object
A durable body paired with a replaceable cutting element separates the long-life component from the wear component. That is sensible product architecture.
It also changes the psychology of ownership. The expensive part is not being sacrificed every time the edge encounters a dirty cardboard box.
One-hand deployment
PICHI designed the G9 around a sliding mechanism that can be operated with one hand. For an everyday tool, interaction count matters. The object is useful partly because reaching the blade does not become its own project.
Small enough to survive the edit
Eighty millimeters is a little over three inches. At that scale, the G9 can deliver a useful cutting edge without occupying the pocket volume of a conventional folding knife.
The engineering achievement is not that 55 grams is impossibly light. It is that the tool is light enough that carrying it can stop feeling like a decision.
The replaceable-blade idea
Durability does not mean pretending nothing wears out.
One of my favorite design ideas is honest wear.
Some products are built as though admitting a component will eventually become dull, dirty, depleted or damaged would be a moral failure. Better products identify the sacrificial component and make it replaceable.
Cars have tires. Printers have ink. Mechanical pencils have lead. Utility knives have blades.
The G9 makes the body the object you form a relationship with and the blade the thing you consume. That is a mature division of labor. The titanium can accumulate scratches and history while the cutting edge can become new again in seconds.
There is also a quiet sustainability argument here. A long-lived housing around a standardized or readily replaceable wear part can make more sense than discarding the whole tool when the functional surface is exhausted.
More importantly, it makes the tool less precious. Good EDC should invite use, not require a velvet rope.
The X2 idea
A multitool does not have to contain a hardware store.
PICHI's X2 lineage is useful for understanding the company's design instincts. The company says the original X2 spent 11 months being designed, built and tested, with research among EDC users identifying cutting, wrenching, screwdriving, prying and bottle opening as desirable everyday functions.
The resulting titanium tool weighs about 44 grams according to PICHI's published material. The original X2 integrates a replaceable No. 11 blade, a multi-size wrench, pry functionality, a magnetized 1/4-inch screwdriver slot and bottle opener among its functions.
PICHI's later X2S continues the minimalist multitool idea. Current company material describes the X2S as solid titanium and focused on practical tasks such as prying, fastening, opening and cutting rather than maximum tool count.
This is a useful counterpoint to the classic folding multitool. Instead of asking, “How many implements can we hide in the handles?” PICHI asks, “How much utility can the shape itself perform?”
NODE-1 modular capsule
Then PICHI applied the same editing instinct to a container.
NODE-1 may be the most revealing product in the group because a capsule is almost aggressively simple. It is a tiny container with a cap. Surely civilization can leave that alone.
PICHI did not.
The company designed NODE-1 as a precision-machined, sealed capsule platform whose function can change. Current configurations include storage, a refillable lighter insert and a screwdriver module. An extension tube can add internal volume, and the screwdriver configuration can carry standard 1/4-inch bits.
The body is offered in titanium or anodized aluminum with a threaded brass cap and silicone O-ring. PICHI describes it as watertight for everyday conditions such as rain and splashes, while explicitly noting that it is not intended as a deep-water dive container.
That last distinction is worth appreciating. “Waterproof” language becomes sloppy very quickly. A gasketed pocket capsule and a pressure-rated diving enclosure solve different problems.
What I like about NODE-1 is the architecture. Rather than stuffing lighter, driver and storage functions permanently into one fat object, the system lets the owner choose the role.
The simplest configuration.
A sealed micro-container for small essentials such as cash, matches or other items the owner wants protected from ordinary pocket and outdoor conditions.
Fire becomes a module.
A sealed refillable brass lighter insert and extension tube turn the capsule into an ignition tool without requiring every NODE-1 to be a lighter forever.
The cap becomes the interface.
A magnetic screwdriver cap lets the system work with standard 1/4-inch bits, while the capsule body can provide storage for multiple bits.
Capacity without redesigning the platform.
An extension tube changes internal volume while preserving the basic modular architecture. The system grows by adding a section rather than replacing the idea.
Why EDC people keep falling for titanium
Titanium is not magic. It is simply very good at this particular job.
Titanium has become almost a cultural material in premium EDC. Part of that is aesthetics. Machined titanium has a cool, technical character and ages differently from painted plastic or plated steel. But there is an engineering reason it keeps appearing in objects meant to be carried.
Titanium alloys can provide an excellent strength-to-weight ratio and strong corrosion resistance. PICHI uses Grade 5 titanium in products such as the G9 and its titanium multitools. Grade 5, commonly known as Ti-6Al-4V, is one of the most widely used titanium alloys and combines titanium with aluminum and vanadium to improve mechanical performance.
The important phrase is strength to weight, not “strongest metal.” EDC is a mass-budget problem. A material can be compelling because it delivers adequate stiffness and durability while allowing the designer to keep the object small and light.
It is also corrosion resistant, which is particularly attractive for something destined to spend years encountering sweat, humidity, rain and whatever mysterious microclimate exists at the bottom of a pocket.
The science of actually carrying something
The best pocket tool has to win an argument every morning.
There is a simple equation nobody writes on an EDC product page: utility has to exceed carry friction.
Carry friction includes weight, thickness, sharp corners, pocket competition, deployment effort, maintenance and the chance that airport security will suddenly become interested in your life choices.
A tool can be extraordinarily capable and still lose that equation.
This is why I think EDC is a fascinating design laboratory. Unlike equipment stored in a garage, a carried object pays rent continuously. It is touching the user for hours in exchange for perhaps seconds of actual work. Its usefulness is therefore not measured only at the moment of use. Comfort while doing nothing is part of the product.
PICHI seems to understand that. The G9 retracts its edge and stays compact. The multitool platform reduces bulk by making the body perform multiple functions. NODE-1 lets modules change instead of demanding that every possible function travel every day.
That is not minimalism as decoration. It is minimalism as economics.
A pocket tool spends most of its life not being used. Designing that inactive state well may be the most important feature of all.
The thing I think PICHI gets right
Prepared does not have to look paranoid.
EDC culture can occasionally wander into theater. There are loadouts that suggest the owner expects to repair a helicopter, escape a maritime disaster and open a craft beer before lunch.
I am not judging. I own drawers.
But the PICHI objects I like most have a quieter confidence. They are small pieces of industrial design that happen to be useful. The capability is there without becoming the entire visual identity of the person carrying it.
That matters because the best everyday objects become almost invisible. You stop thinking about carrying them. They acquire scratches. You know where they are by touch. They solve small problems before those problems become memorable.
Opening a package is not an adventure. Tightening a loose fastener is not a heroic act. Starting a flame is technology humans have been working on for a while.
The achievement is making those capabilities pleasant enough to keep nearby.
Why it goes in the digital time capsule
I want to preserve the era when ordinary pocket objects became miniature industrial design.
The Things Worth Wanting collection is partly about obvious technological leaps. But innovation is not always a robot, a battery or a processor. Sometimes it is a three-inch object that has been reconsidered with unreasonable care.
PICHI belongs because these products capture several ideas that define contemporary product design.
We have access to CNC machining precise enough to turn small metal parts into tactile interfaces. Premium alloys that once sounded aerospace-exclusive now appear in pocket tools. Standardized consumables can be wrapped in durable housings. Modular systems let one object change function. Direct-to-consumer companies can build communities around objects too specific for yesterday's mass retail shelf.
And perhaps most importantly, design culture has become interested in the ordinary.
A utility knife does not need to be beautiful. A bit holder does not need to make somebody smile when the threads engage. A capsule does not need an ecosystem. Yet there is something deeply satisfying about applying serious thought to humble objects.
That is why I would put the PICHI Daily Kit in the time capsule.
Not because future civilization will need help opening a cardboard box. I assume they will have solved that.
I want them to see how much attention we were willing to spend on the things we carried every day, and how the best designers understood that adding capability was only half the job.
The other half was knowing what to leave out.
A few practical questions
About PICHI's everyday-carry tools
What is the PICHI EDC Daily Kit?
This story uses “Daily Kit” as the editorial grouping for PICHI's compact everyday-carry approach, centered on products such as the G9 titanium utility knife, the X2/X2S multitool lineage and the modular NODE-1 capsule system. Exact bundles and configurations can change, so PICHI's current product pages should be checked when purchasing.
What is the G9 made from?
PICHI offers the G9 in Grade 5 titanium and brass. The titanium version discussed here uses a CNC-machined Grade 5 titanium body.
How large is the titanium G9?
PICHI publishes dimensions of 80 mm long, 16 mm wide and 9 mm thick for the G9, with a titanium-version weight of 55 grams.
Can the G9 blade be replaced?
Yes. PICHI designed the G9 around replaceable utility blades and a tool-free blade-change process.
What is NODE-1?
NODE-1 is PICHI's modular sealed capsule platform. Depending on configuration, it can serve as a storage capsule, a refillable lighter or a screwdriver system, with add-ons such as an extension tube.
Is NODE-1 waterproof?
PICHI describes NODE-1 as watertight for everyday exposure using threaded interfaces and a silicone O-ring, while specifically advising that it is not intended for extended deep-water use.
Why does PICHI use titanium?
PICHI emphasizes titanium's strength-to-weight ratio and corrosion resistance. Those properties are particularly useful in EDC because the object has to survive repeated handling and environmental exposure without becoming unnecessarily heavy.
Where did PICHI Design begin?
PICHI describes itself as a Western Canadian team of industrial designers, mechanical engineers and product engineers. The company says its EDC direction emerged in 2020 from hiking and cycling experiences in the Rockies.
