I love working with the Cubics Interchangeable Needle Tips and would have rated them a full 5 stars except for the fact that I have had 2 size 6 needles snap in half. I don't knit tight and I wasn't forcing or pulling on the yarn. They just split. One broke off right at the place where the metal part starts and the other split vertically nearly the full length of the needle. As far as size 6 goes, I've order one more as I love the feel and the comfort on in my hands, but that's it - three strikes and it's out!
I got these just to see how knitting with square needles goes. It's kind of wild! It's a bit weird, holding on to a square sided needle, but my hand is more relaxed as I grip so I imagine that would lead to begin able to knit longer without stress. I think the shape will take a bit getting used to but the ease of grip will make it worth it. Do wish the cables swiveled, though.
Love my cubics both the sock & interchangeable's butttttttttt they have a flaw, after knitting for a few hours the size notation on each needle was worn off; this didn't please me as having to chase down a needle sizer to check your needle size gets old very soon I knew something was needed to more or less keep the printed size intack , but what? In looking through a drawer one day there was my answer a common everyday item most women have "clear nail polish" I tried it on one needle it worked with no harm to the needle and the printed size was very readable and not worn off. My recommendation is cover your needle size on your needles when you first take them out of the package and their will be no more hunting down a needle sizer.
Knitters Pride Cubic needles are so much easier to use with considerable less pain when you have arthritis. I am now using both the interchangeable and the sock needles getting a lot more knitting without the intense pain I was having.
