Ken Ledbetter's Drop Spindles with a Twist

Many of you are familar with Ken Ledbetter's great drop spindles, but this is something different from him.  He's just come out with a drop spindle that comes with interchangable shafts.  Why would you want differents shafts, you ask?  As you fill one of the drop spindle shafts with your spun fiber (yarn), you can quickly replace the full shaft with a fresh one and continue spinning.  Once they are all filled you can ply them together.

These are for the drop spindle lovers.
