Knives are among the oldest and most versatile tools known to man. I have, on occasion, used my pocket knife as a gardening tool, screwdriver, box cutter, prying tool, wire stripper, wire cutter, torque wrench, and hammer. It is not the best tool for any of the above, but sometimes you just lack the time needed to go back to your garage and get your toolbox.
Nothing about "assisted opening knives" makes them "clearly intended to be used as weapons." It is a convenience, just like my pocket knife conveniently locks open. Why should a tool not be convenient?
Finally, the important distinction here is that Google is not refusing to advertise these knives, they are only refusing to allow this one, small company to advertise those knives. That is a key detail -- Google has no problem with the knives when Amazon is selling them.
Its kind of different though isn't it. Amazon is a very big site and its is pretty unlikely that you would end up at a page that has these knives on it from any of amazons other ads. This is a highly focused website and it is very likely that you will end up on a page with these types of knifes from every single ad that they have.
