I bought this knook set because I liked how complete it was and you can't buy knooks of different sizes in stores where I live. I think they work OK, they feel kind of cheap in my hand and the smaller sizes feel like they are going to snap in half as I use them and are very bendy. The cords start to fray at the ends and they were getting caught on my work when I pulled it through. I'm not sure what I think of the knook. I am an experienced crocheter and beginning knitter and was wanting to learn something new, but so far I have found it to be a little frustrating and prefer traditional crochet and to knit with knitting needles.
I have not experienced any issues using the knook needles. Actually the needles are easy to use. I guess I got a good set, no burr or nicks that catches my yarn. I have made a couple of spa rags and love them they are excellent to exfoliate your face, but can be used anywhere on the body. I would like to challenge someone to come up with a sock pattern using the knook.
I had originally bought the Beginner Expanded Set to see how I liked doing my knitting with a Knook and found I liked the technique, even though it was slower than actually knitting but with my loss of vision I'd had to stop knitting as it was frustrating dropping stitches, etc. The only problem was one wooden Knook was split where the thread eye was and another had burrs on the hook area that my husband had to sand off. Both these caused catching on the tread and yarn. The one with the split at the eye was the H size so the one most of the patterns call for you to use and my threads were all ragged and frayed from the projects I'd made already. I was hoping the plastic ones might be in better shape and the eye for the thread is much bigger although still difficult for me to do myself. There is a burr where the plastic was injected into the mold for manufacturing but that was easy for hubby to remove and I'm halfway though my first project using a plastic Knnok and it's going very well!
although I haven't had the chance to try them yet, because of all the holiday shopping, I really like them. I did purchase the bamboo ones, however found that they break easily during use. These are stronger and like the plastic crochet hooks should last a long time.
