They may look small but they sure can crank out a pair in no time at all!!!!
I use them on my antique sock knitting machine or CSM. The shorter one makes the purl stitch and so that leaves the taller one to make the knit stitch.
In the knitting process, the shorter one lays horizontal while the taller one sits vertical.
So, once again, what needles do YOU use to knit socks? Hmmm? ;)
