I think there's been a rush to conclude (or market) knooking as closer to knitting than it necessarily is. Just because you can use knooking to produce knits doesn't mean that's all it does, or all it's for, or that Tunisian is a kind of knitting, or that knooking is not Tunisian.
Knooking was inspired by an earlier Japanese method called ipponbari, and "miracle needle" ("amazing needle" in the US).
I have three ipponbari books on their way from Japan right now, I can't wait! I love the way crochet, Tunisian Crochet, and knit textures creatively coexist in ipponbari stitch patterns.
