Grass shears comprise cutting blades 10, 12, mounted at one end of a shaft 16 so as to be rotatable to cut in vertical, horizontal or intermediate planes, the movable blade 12 being pivoted on the fixed blade 10 and connected by a push member 36, links 34, 40 and a rod 28, passing through the hollow shaft 16 to a handle 24 pivotally mounted on a fixed handle 26. The fixed blade 10 is mounted on a bracket 48 which is rotatably mounted on a lateral support 14 secured to the shaft 16 by a stub shaft 50 which is rotatable within a sleeve 52, spring-loaded balls selectively engaging apertures 56 in the bracket 48 to locate the blades in the desired position. One or more ground-contacting plastic rollers 58 are provided. Lateral play between the blades is prevented by the spring 20 surrounding the pivot-pin 22 and the blade 12 is laterally inclined to the blade 10 to promote selfsharpening of the blades. In a modification, the member 36 operates as a pulling member 1 and a small hand lever is provided for moving the blades into a different plane.
