The blade release slide element is slidably mountable on the handle and is of a length such that, when in assembled relation with the handle, the blade release slide element extends forwardly from an intermediate section of the grip to a section of the grip rearward of the tang. The blade release slide element has a blade engaging and release ramp which inclines from the proximal end of the handle to the distal end of the handle as the blade mounting portion of the tang extends upwardly. Removal of the blade is accomplished by a one handed digitally activated sliding movement of the blade release slide element towards the proximal end of the …
