There are a lot of different knitting needles that are good for different purposes. Wooden needles are great for grab, while metal needles are good when you want to knit quickly.
When it comes to lace knitting, the ideal needle has reasonably sharp points for easy manipulation of stitches and a little bit of grab so stitches are easier to control. A circular needle with a super-smooth join is great, because circulars reduce knitting strain and make it eeasier to hold the often large number of stitches involved.
Knitters who knit a lot of lace will find all of these things in the Addi Turbo Lace needles.
Addi Turbo Lace knitting needles were designed for lace and sock knitters at the request of fans of other Addi needles. They feature soft cords with very smooth joins -- probably the easiest to work with of any circular knitting needle I've used.
The points of the hollow brass tips are sharp (the Addi website calls them "aggressively tapered"), but not so sharp that you fear hurting yourself when you knit with them. The tips are coated to give the needles a little bit more grab than you can usually expect from a metal needle, and they're quite easy to work with.
The needle is lightweight and comfortable to use and makes the stitch manipulation that's required in lace knitting a lot easier than it can be on some other needles. I was even able to purl 2 together through the back loop, an often tricky maneuver, without difficulty.
Another thing that's really cool about the Addi Turbo Lace needles is that the size is stamped right on the cable, so you never have to pull out your needle gauge or keep the needle in its original packaging to know what size it is.
Addi Turbo Lace needles come in lengths of 16, 24, 32, 40, 47 and 60 inches and in sizes from 000 to 11 US, though some sizes are not available in all cable lengths. Because the needles are made to exact metric measurements, there's also a size 2.75 and 10.75 US.
The needles range from about $12 to about $17 each as of this writing at various sources online, depending on the size of the needle.
If you do a lot of lace knitting, the Addi Turbo Lace needles are well worth the investment. They really do make quicker and easier work of lace knitting, making it more comfortable and more fun to knit lace.
Like other Addi needles, they are expensive for a single needle, but I'm a big believer in the idea that nice tools (needles and yarn) make knitting even more fun and luxurious than it already is.
Knitters who've been frustrated by lace knitting in the past because they found the stitches difficult to deal with should consider trying out a pair of these needles, too; they'll make the job easier.
