When something is new and lots of people use it for a relative short period of time and then revert back to what they used before, I call that a fad. People used teeth for a while, then they probably used knifes. Now the majority of people that I see use guillotines or scissors. My 99 cent cutter chops the cap off and I can smoke just fine. My teeth dont come together so I can't use them.
The Razor scooter is also a fad. They will probably sell thousands of those soon.
Good info about the types of cuts Slim. Damn Im bored. I wish I was not at work.
