This issue is already being discussed in various locales throughout the world. It's only a matter of time before central governments begin to follow the lead. For example, Oklahoma's HoR recently debated Bill 1492 entitled, 'Initiative to Regulate Sharp Edges' which would require all knives (defined as 'thin, tapering surfaces attached or unattached to a holding device') to be registered individually and require a license to handle, the requirements of which involve a criminal background check, urinalysis, a game of euchre, and a cooking course, among other things. This, to me, is a great leap forward in the War on Edges.
Ahahahaha. Tik, you do realize the British actually are looking into things like that right?
