a handle including an end face having a first locking element;

a blade pivotably connected to the handle in a manner allowing pivoting of the blade from a closed position in which the blade extends along the handle, to an open position in which the blade extends away from the handle;

a slot in the blade, the slot including a narrow region and an wide region;

a post having first and second knobs, and a neck portion extending between the first and second knobs, the neck portion positioned in the narrow region of the slot for sliding movement along the blade, the post being movable within the narrow region of the slot between a first position in which the post engages at least part of the first locking element in a manner preventing pivoting of the blade relative to the handle, and a second position spaced from the first locking element in which the blade is free to pivot relative to the handle;

a retaining element positioned in the wide region of the slot to prevent movement of the post into the wide region of the slot while permitting movement of the post between the first and second positions; and

the end face of the handle being configured such that, as the blade is pivoted from the closed position towards the open position, the post, when in the first position, is spaced from the end face of the handle for at least approximately 75% of the total travel of the blade from the closed position to the open position.
