Crochet Hooks by Addi Turbo are made in Germany and are very fast hooks. If you like a smooth finished hook you will love the Turbo. Ergonomic handle is easy to hold and won't make your hand sweat or rub the side of your finger. The handles on the metal hooks are all the same size (about 3/8" diameter) so even the smallest hook is easy to hold. Color coded for size. The size 6 to 16 hooks have a handle cap, like a pen, that removes and covers the hook when not in use. This protects the tip from accidental breakage. These are the best hooks made. Note: Sizes J to O are high quality plastic with smooth handles made of clear lucite with gold sparkles in the plastic. Prices vary according to size.
