Neko's curved double-pointed needles make it easier to knit in the round. Stitches stay on two needles, flowing around the bends to keep them in the round, with the third needle acting as the working needle. There are fewer moving parts than straight dpns, so less chance of losing stitches off the end of a needle, and reduced laddering.
When not knitting, move all stitches to the bent portion of the two needles holding stitches and they will all remain secure in your project bag. When ready to knit again move your working yarn and stitches from the bend to the straight part of the needle and you are ready to continue.
Each set contains three needles. The following sizes are offered in the shorter length for socks, sleeves, and tiny things (approximately 4" from bend to tip)
