BONEBREAKER G
HAMMER FIDGET SPINNER · DESIGNED BY NAYICI
CLICK IT. SPIN IT. SWING IT.
A hammer you can spin. A spinner that transforms.
01 / ABOUT
Not a hammer.
Not a spinner.
Both.
This is the Bonebreaker G — a hammer-shaped decompression spinner designed by NAYICI Studio, co-released with MUYI and AMMO. It looks like a precision-machined hammer. It spins like a top-tier fidget toy. And it transforms faster than you can put it down.
Flick it open with one hand and the magnetic armor plates deploy into a full fidget spinner. Unscrew the handle and you've got a compact spinner body on its own. Four Mokuti or Zircuti gemstones sit at the core — each one also a tritium vial slot for 1.5×6mm tubes. Diamond-cut facets. Dual bearings. Solid, satisfying weight in the palm.
Click it. Spin it. Swing it. Wear it. It's not one thing. It's everything your fingers want — all packed into a single machined piece.
02 / PLAY MODES
One hammer.
Three ways to fidget.
MODE 01
CLICK
One-handed open and close. Each flick delivers a crisp, loud mechanical click. The satisfying kind you can't stop doing. Hammer handle locked in.
MODE 02
SPIN
Dual bearing system. Magnetic armor plates deploy outward when spinning — centrifugal force opens them up. Longer spins, more drama, zero contact.
MODE 03
DETACH
Unscrew the handle and the hammer head becomes a standalone fidget spinner. Compact. Pocketable. Perfect for the desk or on the go.
MODE 04
WEAR
Bottom lanyard loop for paracord, beads, pendants — the whole EDC ecosystem. Pair it with Orlov pendants or build your own chain. Modular from end to end.
03 / MAGNETIC ARMOR
Closed — a solid billet.
Spinning — armor deploys.
The magnetic armor plates are the signature feature of the Bonebreaker. At rest, they sit flush — the hammer looks like a single solid piece of machined metal. Start spinning and centrifugal force pushes the plates outward, transforming the profile mid-spin.
It's not just visual — the outward-shifted mass changes the momentum and feel of the spin. Heavy at the rim. Stable in the hand. A fidget toy that puts on a show every time you flick it.

Same hammer.

05 / TRITIUM
Four gem slots.
Four tritium slots.
Each of the four gemstone positions on the Bonebreaker doubles as a tritium vial slot — 1.5×6mm size, press-fit, no glue. Pop out the Mokuti or Zircuti gem and drop in a tritium vial. Or leave the gems in. Or mix and match — two gems, two vials. Whatever your setup calls for.
The gemstones themselves are hand-cut Mokuti or Zircuti — every single one has a unique pattern. No two are the same. Your Bonebreaker is one of one, straight out of the box.
Tritium vials sold separately. Compatible with standard 1.5×6mm size.
06 / MODULAR
Build your setup.
The bottom lanyard loop connects to the full EDC ecosystem — paracord, lanyard beads, pendants, the Orlov lineup. Thread it through, add a bead, hang it from your bag. The Bonebreaker isn't just a fidget toy — it's a piece of your carry.
Pair it with an Orlov pendant for a full chain. Stack beads. Add a lanyard. Detach the spinner body and keep the handle on your keychain. However you set it up — it's yours.
07 / SPECS
The numbers.
08 / CARE
Keep it hammering.
Bearing maintenance
Clean bearings with isopropyl alcohol if grit gets in. Lubricate lightly with bearing oil for longer spins. Dry spin if you prefer silence.
Material care
Titanium and zirconium develop patina with wear — that's normal and desirable. Wipe with a soft cloth. PEI is durable but avoid high heat.
Tritium note
Tritium vials are not included. Compatible with standard 1.5×6mm tritium vials. Press-fit into gem slots — no adhesive needed.
09 / FAQ
Questions.
Is the handle detachable?
Yes. Unscrew the hammer head from the handle and you get a standalone fidget spinner body. The handle also has a lanyard loop for keychain or paracord use.
How does the magnetic armor work?
The armor plates are held flush by magnets when at rest. When you spin the hammer, centrifugal force pushes the plates outward, creating a larger, more dramatic spinning profile. They snap back into place when the spin slows down.
What are the gemstones made of?
Titanium versions come with Mokuti (titanium damascus) gemstones. Zirconium version comes with Zircuti (zirconium damascus) gemstones. Each gem is unique — no two have the same pattern. They're also interchangeable with 1.5×6mm tritium vials.
Which version should I get?
If you want the lightest, most colorful option — go Violet Titanium. If you want stealth and daily carry — go Black Titanium. If you want the densest, longest spin — go Zirconium. If you want heavy heft and a unique amber look — go PEI.
Does it come with a lanyard or chain?
No. The Bonebreaker G is sold as the hammer spinner body only. The bottom lanyard loop works with any standard paracord, lanyard, or EDC bead setup.
