sable', a very craftsmanlike adaptation of a specialized tool. I grabbed some tapered pipe cleaners at a pipe show, unknowingly. I made them work for a while, but I had already made my adaptations to the regular ones, when to fold them over, how to use them on different size airways, and I didn't feel the tapered ones were helping me. It's like choice of tools in general. Some work really well for some people. If I have any tapered left, in the bottom of the drawer, I may give them another go. But so far, I've been a lot happier with the regulars. I do like bristled (not tapered) for the occasional scrubbing out the airway; supposedly they don't scratch shank or stem materials.
