A replaceable blade knife comprise two elongate handle portions and a blade carrier assembled together; the blade protruding, or being arranged to protrude, from a front end of the handle, between respective front ends of the two handle portions. The upper handle portion has a thumb-nail-sized 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 two downwardly projecting flank portions, each said flank portion having an integral, forewardly projecting piece at the bottom of the flank portion. The front of the tower handle portion is formed with upwardly projecting flank portions, each said flank portion having an integral, rearwardly projecting piece at the top of the flank portion, to overlie and hence interlock with a forwardly projecting piece at the bottom of the corresponding flank portion of the upper handle portion. At the rear edge of the aperture, the upper handle portion is formed, at the bottom thereof, with a forwardly directed projection which engages in a recess at a rear wall of the lower handle portion to interlock the two handle portions together at the rear end of the handle.
