No, I didn't need them, but I finally did it. I bought the new Chiagoo Red Lace Interchangeable set. Yes, they were pricey, but I really am liking the Chiagoo Red Lace needles for knitting. And yes, I still love my Knit Picks interchangeables, but I just had to have this new set.
I was having a little trouble with the drag on my Folk School Shawl now that I have more than 400 stitches on the needles, so I decided to switch the shawl over to the red lace needles on a longer cable for the rest of the shawl.
On the shaft of the needle, there are both the life line holes and a larger hole that I can use my little tool to tighten them up a bit if I want, without worrying about twisting the wood since it is metal. Initially to connect them, they screw together.
This is a nice new addition to my interchangeable knitting needle collection. And I am okay with that!
