One of Havel's most popular products! We've taken the curved seam ripper blade and put it on a stainless handle to cut even the heaviest of threads. Blades can be replaced easily on this screw-lock handle and each handle comes with a plastic cover for storage. This set includes 1 handle, 5 blades and 1 cover. (Packs of replacement blades are available under item #18906). Excellent cutter for thread velvet. See why we call this "the professional's choice."
