the Ballistic Knife Prohibition Act of 1986 was signed into federal law by then-Republican President Ronald Reagan, as part of the Anti-Drug Abuse Act of 1986.
In addition to the ballistic knife being slandered and falsely linked to drug abuse, this was the newest national attack on knives since the 1958 Federal Switchblade Law.
Republican Sen. Alfonse M. D’Amato held a news conference pushing for and spinning the proposed ban. He announced that a ballistic knife “is a favored weapon used by drug dealers.” He further proclaimed, “Ballistic knives are at least as dangerous as switchblade knives that have been banned since 1958.”
