A utility knife comprises two elongate handle portions and a blade carrier assembly carrying a blade arranged to protrude from a front end of the handle. The upper handle portion has an aperture through a rear end part thereof. When the knife is assembled, the two handle portions are slid relatively longitudinally of one another, the upper handle portion moving forwardly of the lower handle portion, until a latch part near the rear end of the lower handle portion clicks into latching engagement with the front edge of the aperture in the upper handle portion. The upper handle portion is formed near its front end with interlocking elements, each having an integral, forwardly projecting piece at the bottom thereof. The front of the lower handle portion is formed with interlocking elements, each having an integral, rearwardly projecting piece at the top thereof, to overlie and hence interlock with a forwardly projecting piece at the bottom of the corresponding interlocking element of the upper handle portion. The upper portion further includes a forwardly-projecting flat tab which is received within a longitudinally-extending slot formed in the forward end of the lower handle portion.
