Slice® makes the first safety seam ripper blades on the market, featuring rounded tips and our signature finger-friendly® edge, which cuts effectively but is safe to the touch. Because our blades are made from 100% zirconium oxide, they are non-magnetic, non-conductive, chemically inert, and never rust. They are also very strong and last up to 11 times longer than comparable metal blades. These smooth, narrow blades slide into stitches and cut effectively without tugging the surrounding delicate material. Four blades per pack.
