Abstract: The present invention relates to an extendable folding saw that is lightweight and compact when retracted yet rigid when extended. In one embodiment, the extendable folding saw can have a folding saw and a removably attached extension. The folding saw can have a grip and a pivotally attached saw. The extension can comprise several members that are compactable to a length not much greater than the length of the longest individual member. The members of the extension can have a generally I shaped profile. The extension rod can be attached to the folding saw in a snap-fitting manner for use. A retracted folding saw can be snapped side-by-side to a retracted to extension rod for storage.

Abstract: The invention relates to a method for the production of synthetic filament yarn having crepe characteristics by simultaneous drawing and falsetwisting of the filament yarn while imparting a twist by means of a falsetwister, as well as--under certain conditions--drawing of the filament yarns to a ratio of at least 1:1.08.
