What Is Difference Between Le Grelots?

I understand that TI sells Le Grelots that were not originally produced by them, but now sold by them. Do they also make Le Grelots that are not original but use the same name?

On a similar note, what makes these different from other comparable size, ground, etc TIs? I guess that question is true of blades in general. (ie. what makes one 6/8 3/4-Full ground shave better than another?)

TI obtained some old LG blanks years ago. They blanks sat around for a few years until somebody said "Hey, lets make these blanks into real blades and sell them!"

I don't know if when TI purchased LG they may have also purchased the right to make blades under the LG name. Matbe sombody else can chime in on that one.
