Abstract
To provide an autoclavable swab, a fibrous applicator pad is formed with a narrow slit and a handle with a plurality of barb means extending away from its longitudinal axis and from a first end toward a second end. The opening is sufficient in size to receive the first end of the handle and the adjacent portion through at least 25 percent of the applicator pad, whereby the barbs, once inserted, engage the applicator pad material within the opening to resist removal of the handle.
