Every knitter has her/his occasional problem with the way yarn of one kind or another moves or slipsover the needles. this can be a good or a bad thing. I was using a particularly soft and therefore slippery type of yarn on bigger #9 needles, and needed to have a little more grip on the yarn than a metal or plastic needle would give me. These Clover needles are perfect for these circumstances. The cable is just a bit stiff, but not enough to forgo using on circular projects. Good needles.
I have several pairs of the Clover Takumi circular needles in larger sizes (for example, size 7) and love them. I just received a 36" (US size 1) and am horrified to find that the needle tip is less than 4 inches in length, more than an inch SHORTER than the tip length on my shorter circulars in larger needle sizes. I do not have petite hands and will probably give these to my granddaughter, who does have small hands. I can understand this shorter tip on a 16" circular, but on a 36"??? Go figure. I cannot find this information in the description, or overlooked it somehow.
I have played around with these needles and I like them tremendously. They hold the yarn very well, no slipping. That can be a good thing or a bad thing depending on what you are knitting. Will definitely purchase again.
