I've used a variety of implements and procedures to fix a tight draw including:
- wood screw
- paper clip
- coat hanger
- wire in general
- drill bit (with and without the drill)
- microwave
- toaster oven
- sun
- rolling between fingers, rolling on the desk
- whatever else I could think of
The best solution is to keep your cigars *properly* humidified and once you are satisified that you have done everything you are supposed to do...I find the *trashcan* to be the best tool to manage a cigar with a tight draw.
