Abstract
A hand held utility knife (20) is provided internally with a rectilinear guidance track (42) for the cutting blade (28), while the operating button (38) for advancing and retracting the blade (28) is guided in a curved slot (40). The mechanism (36) for advancing and retracting the blade (28) comprises a member (44) with a spigot (46) at the front end of member (44) and the operating button (38) at the rear end of member (44), which pivots on the spigot (46) relative to the blade (28). The spigot (46) is rectilinearly guided by internal ribs (64, 66) within the handle (22), independently of the rectilinear track (42) for guiding the blade (28).
