Under a 1981 treaty, at least 50 countries, including the United States, have banned their militaries from employing flamethrowers (as “inhumane”), but entrepreneurs have begun to market the devices domestically for $900-$1,600 each (based on the distance of the flame, at 25 feet or 50 feet). Federal regulators appear uninterested (as the contraptions are technically neither “firearms” nor “explosives”), and only two states prohibit them outright, though a few jurisdictions believe flamethrowers are illegal under fire codes. The Ohio startup Throwflame has sensed the need for marketing savvy and describes flamethrowers as primarily for “entertainment.” (Recent news reports indicate a slight run on sales under the suspicion that authorities will soon realize the danger and outlaw them.)
