The "people" that really need to be examined are the 'doctors' who are making the documentaries against knives.

"It was invented by industrial designer John Cornock, who was inspired by a documentary in which doctors advocated banning traditional knives."

Didn't some 'doctors' make a stink about razor sharp Teflon coated bullets that when fires from a handgun can pierce the bucket of a bulldozer and blow people's heads off when then accidentally shoot themselves in the foot? This article seriously makes me wonder if those doctors were given their degrees, with no schooling, in exchange for putting together the documentary.
