A dual-purpose, hand-held scissors for seamstresses, leather workers, sheet metal workers, and other users which have two unique blades with teeth which will cut a series of proportionately-spaced, single notches (V-shaped indentations) into textile fabrics, canvas, leather, vinyl, sheet metal, and other soft, flexible and pliable materials and trim away excess fabric from the article simultaneously. It (1) saves time by performing two essential functions in one operation; (2) simplifies clean-up after sewing because the original method was very messy as when the individual notches were cut, they would scatter everywhere as they fell away from the fabric; and (3) permits more accurately cut notches which are consistent in size and shape to give the article a neater appearance. The shape of the blades is such that upon applying the scissors into the seam allowance on garments and other work products, the seam will be trimmed smoothly for a designated distance, then a notch will be cut into the seam allowance and simultaneously trim the excess fabric at that point. By repeatedly applying the scissors until you reach the end of the fabric, the entire seam is both notched and excess fabric trimmed away from the seam allowance in the same operation. Notching and trimming excess fabric or material is necessary in the formation of inner and outer curves. The resulting debris would then consist of only one continuous strip of excess material instead of a multitude of small, individual notches in addition to a strip of excess material.
