Why is Panasonic the First to Invent a Two-Way Iron?

Unless my Google skills are failing me, this Panasonic 360-Degree iron is the first iron to have the pointed tip at both sides of the iron. It's been staring us in the face for 100 years, and Panasonic's is first?

By making the back of the iron pointed instead of flat, like every single other iron out there, you can go back and forth with the Panasonic NIW810CS as much as you want without screwing up your ironing pattern and wrinkling what you already pressed. Best of all, Panasonic only charges $50 for this bit of ingenuity. [Amazon]
