My cable knitting used to regularly be accompanied by what we might call "strong language" as I dropped or realised I'd lost my cable needle for the hundredth time..
I love cable patterns, but I was driven to distraction by how easy it was to lose a cable needle or for it to drop out of my stitches at just the wrong moment.
Then I found my first kinked cable needle.
The bend in the middle means you can let it angle from your stitches if necessary when working your cable and it doesn't escape. No more manipulating your other needles while grasping the the cable needle in a death grip.
It will also stay firmly in whatever piece of knitting you poke it through. I have come home from a supermarket shop and discovered one still securely sitting in the shoulder of the sweater I was wearing. I'd only stuck it there for a moment while I answered the phone earlier!
Sometimes there are really simple solutions that make a big difference.
