String Trimmer Lines square

Square

— a fishing line with a tetrahedral section is more expensive than a classic round one, however, it works much more efficiently. So, the sharp edges of the thread cope well with dense vegetation and thick stems, including even shrubs and young trees; and the cut is more accurate and even. On the other hand, such a thread not only has a higher price, but is also consumed much faster than a round one. So it makes sense to use square fishing lines only in cases where the advantages described are crucial — for example, when working in heavily overgrown areas with high thick vegetation.
