Well, I guess I am the poor guy in this group--or maybe the most frugal. I find that the first 3/4" on each end picks up the heavy gunk. So, when used, I clip them off with wire cutters and use each end again. Then fold and swab out the bowl. Then reverse the fold and swab out again with the clean side. Throwing away a pipe cleaner that is only partially used is like knocking out a bowl only half smoked and see that little mound of good tobacco destined to be thrown away.
