ABSTRACT:
The plastics handle 21 of a retractable blade knife 20, which also comprises a blade 22 and a blade-slider 23, is molded in one piece in a two-part molding tool 50 which can mold several such handles simultaneously. The handle has a series of wall portions, 39, 40, 27 and 43, 44, 28, 48 alternating with apertures 45, 46, 29, 49 and 41, 42, 30 along each side 25, 26 respectively, each wall portion on each side being directly opposite a respective aperture on the opposite side, so that molding tool portions 54, 55 of the molding tool can form the inside surfaces of the wall portions for guiding the blade. Wall portions 27 are formed by molding tool portions 56 with gaps 31 for passage of a manually operable part 32 of slider 23, and also act as detents for the slider.
