For the well dressed Man in Black on the hunt

Handheld burner. [Link]

Easy to carry from place to place, a weed burner solves the problem of clearing land. It throws a fan-shaped flame that mushrooms against the ground, stone wall or rock pile to “melt” every growing plant within its range. One model of the burner is self-contained for one-man operation. It has a tank that holds oil for one and one-half hours” work. The handle is constructed for attachment of a shoulder strap or webbing to facilitate carrying. Thetorch also can be used for sterilizing poultry houses, dog kennels and stables.

Right, dog kennels and stables. Not shambling zombies or rampaging triffids. Good cover story.
