This Pym threader is especially adapted to the threading of overlock sewing machines. The set consists of a threader for the upper and lower bobbin hook and another threader for needles. The finely curved steel spring wire with white plastic handle and a hook is first to be slipped under the lower bobbin hook, and the thread clamped into the hook . Thus, the thread can be easily pulled through the eye of the hook. The same is done for the upper hook. The threader for needles works just like a conventional needle threader, but it has easy handling by means of a long shaft made of steel spring wire and a handle made of blue plastic.Ref.
