This Stitching Groover Set by Craftool is perfect for all your hand stitching needs. This design is unlike most groovers. The blade is on the same axis as the handle, providing better control and downward pressure on the blade. The chuck easily locks the blade firmly in place. More than just a groover, it also comes with a small modeling spoon for creasing or decorative borders. Groove width adjusts from 1/16" (0,2 cm) to 1-7/16".
