A knitter's array of needles can be compared to a golfer's clubs or a woodworker's tools. Having the right tool for the job makes the experience not only easier and quicker, but a heck-of-a-lot more enjoyable. That's why most knitters have an arsenal of needles at hand- we want to have the right needle for the project. Size isn't the only important consideration, but material can be vital. Mohair might not he an enjoyable knit with bamboo- it might not slip off the needles nicely, but use a nice aluminum needle and you have the right fit. It could be the opposite for lace- you might want to use bamboo or a needle coated in brass to increase friction so those large stitches don't just slip right off the needle.
That's why it's exciting when a new type of knitting needle is introduced. With the new Karbonz, Knitter's Pride did their research and kept up with a trend, but tweaked it a bit and added a nickle-plated brass tip that is more comfortable on the fingers (not too pointy). I have for you every size of Karbonz 6" DPs and Karbonz 8" DPs, made from sizes US 000 to US 4.
A couple weeks ago, I gave a try to these carbon fiber composite needles and I really enjoyed how weightless they are. I found the warmth of the needles to be a welcome change, as I usually knit with metal needles and forgot how nice it is to knit with a needle that isn't cold to the touch in the middle of winter. And I'll admit that I was hesitant about the tips being a different material than the rest of the needle, but while I could tell there was a change where the needles went from carbon fiber to metal, it was similar to the same feeling you'd notice anytime you're knitting with a circular needle and the metal needle meets the plastic cable. There was no snagging or annoying jump.
What I also like about these needles is the price - similar needles made of the same material cost considerably more. So this is a great way to try something fun and new, and not break the bank. Give them a try!
