For our second Handmade issue – for which we tasked a cast of designers and craftsmen to create bespoke products – we asked sculptural jewellery maker Hannah Martin to apply her talents to re-designing the humble letter opener. Martin’s creation is now moving from a one-off prototype to a fully-fledged product, with a series of her limited edition openers (in blue and grey) being produced for London’s Design Museum, to celebrate the launch of her collection in its shop.

Martin has joined forces with film director Ian Rodney Wooldridge and cinematographer Pacu Trautvetter of Ipancu Film to show the craftsmanship involved in the making of this piece, as well as the rest of her collection. Produced by Nathan Morse, the three-minute film - set to a soundtrack by Andrew Haines - also gives a rare glimpse of the inner workings of London jewellery district Hatton Garden.
