Adaptive responses to hydrological risk: an analysis of stakeholders

The construction of a folding-blade pocket knife or the like is described having an improved means for mechanically assisting the movement of the blade from a closed position to an open position or the reverse. The means includes a turning handle pivoted to an exposed portion of a blade pivot and a spring-loaded detent element in cooperation with specifically located indentations in the turning handle. Furthermore, a locking lug on the turning handle is provided to cooperate with a recess in the knife handle to prevent unintentional movement of the knife blade.
