Walnut keyrings with magnets for EIGHT & BOB

The project

Archicercle manufactured these keyrings for EIGHT & BOB with a purpose beyond holding keys: they incorporate a magnet that operates an opening and closing mechanism. The work brought together cutting, engraving, recessing the wood and surface finishing.

Manufacture began by cutting the outline and hole with a CO₂ laser. The logo was then engraved with a fibre laser, using lower power and speed settings than those used to create the recess on the reverse.

The magnet recess was also made with a fibre laser. Higher power and several passes over a circular area removed enough walnut to inset the magnet that operates the mechanism. The branding and the recess therefore served two distinct purposes: identifying the piece and incorporating its function.

To finish, the keyrings were sanded with a very fine grit and treated with linseed oil. This finish darkens and protects the walnut, completing the manufacture of the pieces.
