Frequently asked

The KeyRambit is a keychain attachment shaped like a karambit blade, built around a sealed ball bearing at its pivot point. Flick it and it spins freely and stays balanced, the same way a fidget spinner does, but sized and shaped to live on your keyring.

The body is precision 3D printed in PETG, a durable plastic chosen for its strength to weight ratio, so the piece is light enough to carry every day but tough enough to hold up. The pivot uses a real bearing, not a printed hole, which is what makes the spin smooth.

It has a mounting loop that fits any standard keyring or fob clip. Slide it onto your existing keyring next to your key, or use a small split ring or carabiner clip if you want it removable.

PETG handles daily pocket carry, temperature swings, and the occasional drop well. It's a functional accessory meant for regular handling, not a display piece you have to baby.

No. It has no blade edge and isn't sold, marketed, or intended as a weapon. The karambit-inspired curve is there because that shape is what makes the piece spin correctly, not for any cutting function. It's a keychain accessory, plain and simple.

Black, White, and Burnt Titanium (a teal and blue glitter finish) are available now. Gunmetal Grey is coming soon.
