I use my tamper on the charring light. I also use it for when the ash needs to be dumped. I will use the other end of a tamper to stir the ash in the middle of my pipe, gently dump the ash, and then tamp the tobacco on the sides into the middle.
If my pipe starts to want to go out, I just use two fingers on top of the bowl and cover it, draw in a few times to relight the pipe and I am good to go.
