However, after considerable cajoling from the members of the Ravelry Heirloom Knitting forum, I was persuaded to offer the customized needles that I actually use to knit fine lace.
What you have here are carbonized bamboo needles carefully sharpened to fine points and drilled for lifelines. Although the cable is a bit floppy, we have glued, reseated, and polished the joins so they are utterly smooth and perfect.
These needles won't win any prizes for elegant appearance, but they are simply superb to knit with--lightweight, smooth (but not slippery), and snagless.
Beware that they should be considered fragile, so do not use a death grip when knitting with them and keep away from dogs, beavers, and chair seats.
