Five Safety Rules

Backyard BBQs & Balcony Fire Time During the Holidays
Even in your backyard or on a balcony, a little ingenuity is all it takes to enjoy an outdoor vibe. With CHACCARD, one card handles everything—from preparation to being the center of attention.

Saw for Trimming Small Branches & Fire Starting (Flint & Ferro Rod)
- Cutting small branches down to palm-sized pieces with a saw helps the fire catch more steadily.
- Strike the flint and ferro rod to throw sparks onto jute or cotton tinder. For safety, children should only watch—adults handle the tool.
Feather Sticks with a Plane — How to Make Fire Starting Fun
- Shaving the surface of wood lightly with a plane creates curled shavings known as feather sticks.
- Use well-dried wood for smoother ignition. Pile the shavings loosely in the center and aim the sparks to ignite.
Quick Adjustments with the Indigo Metal Flathead Screwdriver
- If you notice loose screws on a windscreen or grill, quickly tighten them with the Indigo Metal flathead screwdriver.
- Reducing wobble improves both safety and heat stability.
- Note: The standard model does not include a screwdriver. Instead, it features a bottle opener and can opener.
Fire Starting & Storage Tips on Windy Days
- Do not place people or flammable items downwind. Sparks can travel farther than expected.
- Keep sparks low, working over a heat-resistant mat or metal tray.
- After use, wipe dry, let it cool completely, then store it away from moisture and out of children’s reach.
Apartment Rules, Neighbor Consideration & Fire Safety Prep
- Open flames on balconies may be prohibited by building rules. Always check first.
- Be mindful of odors, smoke, time of day, and wind direction.
- Keep extinguishing water, a damp towel, and heat-resistant gloves nearby. Confirm full extinguishment before packing up.
Small Touches for Better Photos
- Shoot the ignition moment from a slightly rear diagonal angle to capture sparks beautifully.
- Arrange feather sticks in a fan shape to add depth to photos.

The flathead screwdriver lets you quickly fix minor looseness in chairs or grills. The JAPAN BLUE metal, dyed using a traditional technique that develops character with use, offers a true one-of-a-kind appeal.
If You’re Unsure, Use This Guide
- Home drinking & mood-maker → Standard Edition
- Tool lover who cares about looks → Indigo Metal
- Both situations → Keep the Standard Edition at your family home, and carry the Indigo Metal yourself
Note: Both versions share the saw, plane, fire starter (flint & striker), and cord cutter.
The only difference is “bottle/can opener” vs. “flathead screwdriver.”
Why It Earns Its Reputation — Craftsmanship by Tenken Industry
When someone asks, “Where did you get that?” at a year-end gathering, there’s a story you can proudly tell.

Hand-Finished by Craftsmen in Seki, Gifu — the City of Blades
Founded in 1926 in Seki, Tenken Industry hand-finishes each piece, adjusting the fine “fit” to within 0.1 mm.
That precision is why gripping, shaving, and striking all feel so satisfying.
Comfort Born from ‘Fit’ Technology
The precision honed through tweezers and hair-removal tools lives on in this card-sized tool.
Angles, spring tension, and subtle bends—areas impossible to fully standardize—are optimized by skilled hands, creating a fit that makes first-time users say, “This feels different.”
Tsubame-Sanjo × Seki — Division of Labor That Delivers (Standard Edition Saw)
The saw is produced by a long-established maker in Tsubame-Sanjo, Niigata.
Their century-old blade know-how ensures reliable cutting even at card size.
Indigo Metal × Seki — The Beauty and Durability of JAPAN BLUE
Indigo Metal is dyed with natural indigo using a unique metal-dyeing process.
Each piece is layered by hand, resulting in a truly one-of-a-kind finish.
Available patterns: HONOO, HANABI, TSUCHIME.
As it’s used, the character deepens. Indigo is also known for deodorizing and antibacterial properties, helping keep it clean over time.
The Pride of Seki, One of the World’s Great Blade Centers
From swordsmiths onward, the spirit of “never breaking, never bending, cutting well” lives on.
Tenken Industry carries this DNA into modern tools, balancing professional-grade function with everyday usability.
In Short:
CHACCARD’s reputation isn’t just about looks.
It’s the precision, sharpness, and careful finishing inside that let you recommend it with confidence at year-end gatherings.
