The Verna-X comes in a few sizes and styles.
The Large is the 1mm one. This is a stainless steel straight needle, 1 mm x 7-1/2" with a blunt point and an in-line crochet hook on one end and a curve on the other to allow it to be used with a bead spinner. This size will work perfectly for 6/0 beads with fingering weight yarns. Stops are provided for each end.
And the Small one is 0.8mm and made of the same materials and the same basic shape, this time 0.8 mm x 7-1/2", again with a blunt point and hook on one end. And again, it will work well with a bead spinner if you so choose, as well as being a marvelous tool to add beads to stitches as one gets to them in knitting. This size was created for 8/0 beads with lace weight yarn as well as 11/0 beads with cobweb weight yarns. It will actually hold 125 of the 11/0 beads. Again there are stops provided for these.
