<p>A hand tool for loosening cutting and crumbling soil or the like, comprising a central bearing axle of an angular cross section, a plurality of pairs of pronged wheel arrangements having radially extending prongs and being freely rotatably mounted on said shaft such that the vertcial central planes of the pronged wheels extending in the direction of extension of the radial prongs intersect one another at an acute angle, and wherein the edges of every two adjacent crosswisely interengaging pronged wheels slide along one another to form cutting regions; wherein a blade-type tine or prong is disposed between every two pairs of intersecting pronged wheels. The blade-type prong is mounted on said axle which may be angularly orientated, as desired, by adjusting the inclination of said handle means such as a shaft non-rotatably mounted on said axle. Alternatively the axle may be mounted on frame means. In one embodiment, the handle socket connecting member is rotatably mounted on a pin secured to the axle and has interengaging means permitting adjustment of the connecting member.</p> |
