Are you forever snapping needles? Or do you prefer metal to wood but wish it wasn’t quite so slippery? Karbonz are your solution! These things are super duper strong so you won’t snap them (even if you step on them, so tread carefully!) and the surface, though definitely not wood, has slightly more friction than metal. They’re also warm to hold rather than chilly like metal can be.The interchangeable system is great: buy the tips in the size you need and a cable in the length you need, and Bob’s your uncle. Need the same size but in a longer length? Just buy a new cord – no need to shell out for an entirely new needle. Need to switch to a larger or smaller size for the next row? Replace the tip you’re going to knit onto (the right tip) with the new size, knit the next row, then replace the other tip with the new size. Hey, presto!3.0 mm is the smallest size Knitters Pride makes as interchangeable because the connectors are at least that big. If you want smaller sizes, check out the selection of fixed circular needles instead.
