Knook

This is a beautiful soft wooden knook in the Symphonie Natural range by KnitPro. It's just over 15cm long, with a lovely big 8mm long hole to hold your knooking cord. The hook's head is tapered. I find the tip of this hook a little sharp for some yarns, especially splitty rayons. You might like to sandpaper down the tip slightly if you're having trouble.
