Leica Camera AG is a well-known German company of cameras and optics. • The partnership between 1515 and LEICA was first signed between 1515, Marcello Pettineo and LEICA. In fact, when the brand launched the telescope (Magnus), two artists, a painter and a cutler, joined forces with Leica. Leica then sent the 1515 from the MM collection with the "Magnus" logo on the blade as a proof of appreciation and brand awareness for its most loyal customers. • The new knife that represents this partnership is the grey 1515 G10 with the "LEICA" logo on the blade.
