Abstract: A simple hand held tool for removing climbing protection, with said tool's body comprising at least two sub-assemblies connected by a joint, rendering the tool able to modulate in size (by collapsing, folding, retracting, extending etc.). Size modulation additionally provides coverage or protection of the tool's hooked tip. This manually operated tool increases a user's safety and freedom of movement by modulating tool size, and preventing the nut tool hook or shaft from being a hazard or interfering with the user's activities, yet preserving normal nut tool function when in a deployed mode.

Abstract: A safety apparatus on a rope, comprising a housing for guiding the rope, a clamping mechanism such as a trigger configured to release or clamp the rope against the housing, and a control mechanism, wherein the control mechanism comprises a rope end sensor which is physically displaced by the rope. When rope no longer displaces the rope end sensor, such as when the rope end has passed by the control mechanism, the trigger is biased to an active, clamped position thus halting the rope between the trigger and the housing.

Abstract: This disclosure relates generally to a safety apparatus on a rope, comprising a housing for guiding the rope, a clamping element such as a trigger designed to release and clamp the rope against the housing, and a control element, wherein the control element comprises a rope sensor able to be actuated, which enables movement of the trigger to an active, clamped position thus halting the rope between the trigger and a housing.
