If It Fits in Your Wallet, You’ll Carry It Every Day
Credit-card size, ultra-thin, and lightweight — portability by design
CHACCARD is a credit-card-sized survival tool designed to live in your wallet.
Its ultra-thin profile fits neatly into a card slot, and its lightweight construction ensures it never feels bulky — even in a minimalist wallet or pocket.
The key idea is simple.
Emergency tools are useless if they stay at home.
Because CHACCARD fits in your wallet, you carry it every day.
And because you carry it every day, you can rely on it without hesitation when it matters.
Built on the philosophy of EDC (Everyday Carry), CHACCARD seamlessly bridges daily life and emergency readiness without adding friction or weight.
Minimal design that fits perfectly into a lean EDC setup
Minimalists carry only what they actually use.
CHACCARD is designed with that mindset, focusing on the most frequently needed actions.
Opening packages
Light cutting
Scraping and scoring
Simple prying and turning
By eliminating unnecessary protrusions and maximizing flat surfaces, CHACCARD avoids interference with other cards in your wallet. Its clean, minimal form keeps your total EDC weight low, even when paired with keys, a mini flashlight, or a tape card.
It’s a tool that respects the “minimum viable EDC” principle.
Designed for everyday convenience — not just emergencies
“Survival tool” may sound extreme, but real value lies in solving small, everyday inconveniences.
Opening cardboard boxes
Removing tags or loose threads
Opening bottles
Quick tasks that save time and reduce friction
These daily wins are what make CHACCARD indispensable.
And when power outages or disasters occur, that familiarity becomes confidence.
CHACCARD is thin, light, and credit-card-sized — finished with the precision of Japanese craftsmanship.
It’s not just a survival tool. It’s a daily-life extender designed for smooth, reliable use.
Japanese Craftsmanship — Precision from Seki City
0.1mm-level alignment and edge control
CHACCARD is finished in Seki City, Gifu Prefecture, Japan — a town known for blade-making for centuries.
Precision alignment matters. Even a 0.1mm deviation can cause drag or frustration during simple tasks like opening boxes or peeling labels. Skilled craftsmen fine-tune edges by sight and touch, adjusting bevels, chamfers, and angles.
The result is a rare balance.
Edges that bite when needed, yet glide smoothly when they should.
Materials and surface finishing
CHACCARD is made from corrosion-resistant stainless steel, ideal for daily carry exposed to sweat, rain, and humidity.
Surface finishes such as fine hairline or blast textures provide a smooth yet non-slip feel. Only necessary edges are sharpened; all others are carefully chamfered to protect your wallet, cards, and fingers.
Flatness is preserved without sacrificing strength, maintaining portability without compromise.
OEM-level inspection standards
Tenken Kogyo has decades of experience manufacturing professional tweezers and precision tools for OEM clients. That expertise translates directly into CHACCARD’s quality control.
Each piece is inspected for burrs and surface imperfections, consistent corner radius, and straight, uniform edges.
This minimizes variation between units — an essential quality for an everyday tool you rely on daily.
The DNA of Tenken Kogyo
Founded in 1926, Tenken Kogyo carries forward Seki’s blade-making philosophy: unbreakable, unbending, and reliably sharp.
That philosophy now lives in tools designed for modern daily life.
CHACCARD may look minimal, but once you handle it, the difference is clear.
What Can It Do? Practical Use from Daily Life to Light Survival
Everyday cutting: boxes, strings, tags, threads
CHACCARD excels at light cutting tasks.
Opening shipping boxes
Cutting packaging straps or tags
Trimming loose threads without damaging fabric
Because it’s always in your wallet, it’s ready the moment you need it — safely and discreetly.
Outdoor support without replacing a knife
In camping or hiking, CHACCARD acts as a safe auxiliary tool.
Scraping wood shavings for tinder
Tidying cords and labels
Scoring packaging for easier opening
It’s not a knife replacement. It’s a minimalist companion designed for control and safety.
Emergency improvisation
In power outages or disaster scenarios, CHACCARD supports quick, calm responses.
Shaping tape for temporary repairs
Forming small sticks or hooks
Modifying bottles or packaging for easier distribution
Because you use it in daily life, you already know how it behaves.
That familiarity matters when conditions are stressful.
