The list of issues that bother me is so long.

What does it take to make a good broom?  Is there a reason the broom head is screwed onto the handle?  How many times have you replaced the handle of the broom?  Or, changed the broom head?

I am left-handed so it's possible that's the reason for this problem, but when I sweep, the broom head becomes unscrewed from the handle.  It's annoying.
