An ultra-violet (uv) knife sterilising system (1 ) comprises a knife sterilising cabinet (100) for sterilising hand knives (2, 3). The cabinet comprises a housing (10), a cavity (12) within the housing and at least one uv light source (16) that is configured to illuminate the cavity with uv light (17) for sterilisation of a knife within the cavity. The knives (2,3) to be sterilised will normally have a handle (22), a blade (23) and a shoulder (27) between the handle and the blade. The housing has a pair of apertures (4,5) each affording passage (20) for a corresponding knife inserted blade-first into the cavity. The cabinet has at least one pair of blade guides (4, 5, 26, 28) within the housing that are configured to engage with a knife to guide movement of the blade during insertion and removal of the knife. Within the cavity is at least one pair of carriages (34, 34) moveable along opposite first and second directions (36,36) relatively away from and towards a corresponding aperture. Each carriage carries an abutment (38) for making abutting contact with the corresponding knife shoulder during the guided movement of the blade. The pair of carriages are interlinked (40) whereby, in use, movement of a first carriage (34) in the first direction (36) caused by the abutting contact during insertion of a first one (2) of the knives through a first aperture (4) causes movement of a second carriage (34) in the second direction (36), such that a second one (3) of the knives previously inserted into a second aperture (5) is moved outwards from the second aperture to assist removal of the second knife from the second aperture.Un système de stérilisation de couteau ultra-violet (uv) comprend une armoire de stérilisation de couteau (100) pour stériliser des couteaux à main (2, 3). Larmoire comprend un boîtier (10), une cavité (12) à lintérieur du boîtier et au moins une source de lumière uv (16) qui est configurée pour éclairer la cavité avec une lumière ultraviolette (17) pou
