Prym Double Ended Crochet Hook, Aluminium, 4mm-7mm
Made by Prym, the same German company that produces the KnitPro needle range.
This hard to find crochet hook has not just one but two hooks - one on each end.
This type of hook is predominantly used in Tunisian crochet (also known as Cro-Hooking or Cro-Knitting).
Having two hooks on opposite ends will allow you to create two-coloured pieces that will have dominantly one colour on one side and a different colour on the reverse side.
Double sided crochet hooks are also indispensable for doing Tunisian crochet in the round.
Available in two lengths, 15cm and 25cm, and different sizes.
