What this? You mean this is a banned item? What are they going to ban next?

NO it is NOT BANNED...being ignored by embarrased/or incompetent US authorities. (from the Italian article...this happened in FEB)

[note discovery happened accidentally...the Italian engineer wore a thin flight suit to airport, forgot he had knife in pocket...then tested it at numerous airports....what he did not realize THEN was that the fabics ARE commercially available in some common clothing]

"The material in question is called Teflon Protector and is commonly used in designer overcoats,windbreakers, and down jackets...... "It is a purely physical phenomenon," explains aeronautics engineer Carlo Viberti of the Turin Cosmo Association, the man who made the discovery. Teflon is a fibre based on complex molecules known as
tetrafluorocarbons, which, thermomechanically, make for a highly resistant membrane. This material is extremely porous, but impervious to metal-detector waves, therefore affording approximately 60 percent
"coverage." What this means is that, depending on the metallic mass being transported, fabric thickness, transit speed through the detector
frame, and detector emission power, the alarm can easily fail to go off."
