I saw this on someone's blog, not sure where so I could give her credit. Any way its a crochet hook on a key type chain. You know when you are somewhere and you have dropped stiches and panic! Well this little gaget is a saviour. I have to admit I made mine for me. I took a size K alum hook drilled a hole in the flat part then used a hack saw to cut off the end just where the flat part starts. added the hook gizmo and there you go!!
