Having said that, I hope knife companies step up and counter some of the negative publicity but they just seem to want to lay low and hope it goes away.
+1 on that.
Knife companies have the resources and the organization to advertise, use public relations firms and lobbyists, etc..
If they keep "laying low" as you say, the government will encroach further and further and soon we here in the US will all be carrying UK Pen Knives
or SAKs
