VERSATILE PINKING SHEARS - An essential for your sewing box. The sharp blades are saw-toothed/ arced instead of straight leaving a zigzag pattern as you cut, the sawtooth/ arc pattern can limit the length of the frayed thread of unfinished cloth edges and thus minimize damage.(Note: There is some oil in the blades, and it prevents rust. So before using it, please wipe it up.) | ERGONOMICS GRIP USE
