Most of the markings as joe said, such as Eagle, are used for different vendors so not two vendors in the same sales are (USA) will have the same production razors. On special editions...damascus, etc....they will often use different handle materials so each dealer has something unique.

The more specialized names come from a list of trade names TI has used in the past and will often resurect them for a new dealer.

I wn 14 TI razors now from the least expensive to the most and love them all. Actually with the exception of a few very old meat choppers and one Filarmonica they are the only brand I own and use right now.
