Congratulations, I am green with envy. Both for the razor, and a girlfriend cool enough to give you such an incredible gift. If she did this by accident, I can only imagine how she would treat you on purpose, lucky man.

Tamahagane steel razors are very highly prized. Same steel as traditional samurai swords made during the old glory days. I would very much love to own just one, just because of the awesome pedigree, regardless of the shave.
