Walnut keyrings with magnets for EIGHT & BOB

The project

We manufactured keyrings for EIGHT & BOB that combine brand identification with a specific function: housing a magnet that operates an opening and closing mechanism. The work brought together laser cutting and engraving, preparation of the magnet recess and wood finishing.

The outline and hole of each keyring were cut from walnut using a CO₂ laser. We then used a fibre laser to engrave the logo at low power and speed settings.

The reverse required a different operation: creating a circular recess in the wood to house the magnet. We increased the fibre laser’s power and made several passes to form this recess. The magnet was then embedded in it to operate the mechanism’s opening and closing system.

To finish the pieces, we sanded them with a very fine grit and applied linseed oil, which darkens and protects the walnut. This completed the manufacture of a personalised keyring in which the engraved branding and the magnet recess serve two different needs within the same piece.
