The invention relates to a dual-function tool, i.e. having two interchangeable tools, one providing a shovel function and the other providing a fork function, both suitable for digging the ground. For this purpose, the tool comprises a shaft (1) with one end provided with a cross-piece to form a cross-handle, and the other end provided with means for mounting a digging tool (3-3′), such as a shovel or fork, such that the corresponding shaft (1) comprises at least two sections (1′-1″) which can be removably screwed to one another, the cross-piece of the upper handle comprising a T-shaped connector (5) which can be removably coupled on the upper end of the shaft, and two side elements (7) which can be screwed onto the end of each of the side arms of the T-shaped connector, together forming an upper cross-piece having an oversized length. The interchangeable tool is mounted on the lower end of the shaft (1).
