well the ones i have are flex shaft...basically they have points like a circular needle so they fit in the hand nicely but the rest of the shaft is like a circular needle cable with a stopper at the end. They are good for the person who likes knitting with straight needles but wants that flexible shaft for comfort. i haven't used mine in about a year because i just do the circular needles. They work great though....except for the constant dropping of the needle!
