>>1084855Zippo actually makes pipe versions of their lighters. I've tried butane jets, soft flame, and matches and I'd say the zippo pipe lighter works the best of any I've tried.
As you can see the flame is designed to exit from the sides of the lighter instead of the top so that you can light it, turn 90 degrees and then draw the flame directly down into the bowl from above without having to pass a flame over the lip of the bowl
