addi Express Hook Express Hook is a super accessory for all cranking fans. Its especially well suited for working with the addi Express machines or for use with complex knitting and crocheting techniques. If a thread has slipped, then you can use the hook to quickly put everything back in the right place, and with both sides you can reach all of the threads in and around the machine. For example, you can use it to cast stitches on or off again - and its actually easier than with your fingers. Made in Germany
