Interchangeable Hooks

[Sandystitch]

I have a set of the Denise Interchangeable crochet hooks with the 'cords', but I'm not doing very well with them as they are plastic.  Can somebody please tell me if there is such a thing as metal ones?  

 

The only interchangeabIes have been able to find so far are the Boye ones but they only attach to a handle.  I want to use the hooks for Tunisian crochet.

 

I have a set of Knitpro metal tips and ideally would have liked to supplement this set with crochet tips so I could make use of the cords I already have, but I can only find plastic tips to fit these cords.  

 

TIA for any info you are able to provide.

Addi makes a set that has six aluminum hooks and two plastic http://www.crochetinsider.com/bookreview/addiclick-interchangeable-crochet-hooks-cable

You can try rubbing them down with waxed paper.  It helps a lot to make plastic hooks smoother.

Thank you both for your help, for the link and the hint on improving the plastic hooks.  I'll try that first
