A mountaineering implement comprises a handle (1), a toolhead (3) mounted at one end (2) of the handle (1) and at least one tool (4, 5) releasably fixed to the toolhead (3). The toolhead has a slot (8) and the tool has a plate-like appendage (18, 26) slidably inserted and locked within this slot. Two opposing flat faces of the slot each have at least one rib (10) extending parallel to the direction of sliding of the plate-like appendage (18, 26) in the slot and each of these ribs (10) is engaged in a corresponding groove (20, 28) formed in the surface (19, 27) of the plate-like appendage of the tool (4, 5). In a preferred embodiment, the toolhead is constituted by a folded sheet-metal blank and provides for the use of two tools, the plate-like appendages of which engage in opposite ends of the slot and have complementarily-stepped ends (21, 29) which contact each other.
