Tandy Leather Factory-Pro Stitching Groover Set. This product design makes perfect sense! Unlike most groovers, this 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. Groove width adjusts from 1/16 inches to 1-7/16 inches. This package contains one pro stitching groover and one small modeling spoon for creasing or decorative borders. Recommended for ages 8 and up. WARNING: Choking Hazard-small parts. Not recommended for ages 3 and up. Imported.
