Uses: Preventing fabric fraying: Primarily used in sewing to cut fabric edges in a zigzag (sawtooth) pattern, which helps reduce thread fraying at the edges. Decorative finishes: Can be used to add an aesthetic touch to the edges of fabrics that do not fray easily, such as felt or wool. Reducing seam thickness: Helps reduce the thickness of fabric edges when sewing corners or curves for a smoother appearance when ironed. Regarding the manufacturer: The image shows an engraving on the shears that reads "MADE IN GERMANY", indicating it was made in Germany, a country historically known for the quality of its metal tool and sewing shear manufacturing.
