While I do not do crochet, I do use hooks for my knitting for catching dropped stitches and doing borders. This is an improvement on the standard hook and will be perfect for socks and fingerling/lace weight yarns I use for lightweight scarves and sweaters!
It is such a joy to knit with these - they make you feel very elegant and more importantly, your yarn slides quickly but not too quickly! off your needles! So much better than bamboo and good for those of us who are still a bit timid to try Addi. They have a nice point - better than the dull bamboo needles, so they slide under the yarn easier fewer split yarns.
