Crochet Hooks by Addi Turbo are made in Germany and are very fast crochet hooks. If you like a smooth finish crochet hook you will love the Addi Turbo crochet hook because you can crochet more quickly with less fatigue. This crochet hook has an ergonomic handle and is easy to hold. It won't make your hand sweat or rub the side of your finger. The handles on the metal crochet hooks are all the same size (about 3/8" diameter) so even the smallest hook is easy to hold. Sizea A to J are color coded for size. The size 6 to 16 crochet hooks have a handle cap, like a pen, that forms the handle and is removable to cover the hook when not in use. This protects the tip of the crochet hook from accidental breakage. These are the best crochet hooks made. Note: Sizes K to O are high quality plastic with smooth handles made of clear lucite with gold sparkles in the plastic. Prices vary according to size.
