Flair Angular Pen
Girish Lone, IIT Kanpur, India
This is a ball point pen with "strangely" shaped front tip, called Angular Tip by the manufacturer. This angular point adds nothing to the utility on the contrary only adds to the inconvenience while writing.
Most of us (95%) have the tendency to rotate the pen while writing, mainly to relieve the stress in the forefinger. But here due to this twisted angular design it is not possible to use the pen in other directions as shown in the figure.
In addition to that it requires holding the pen very close to the tip, as it might loose the balance and leave a mark on the page. Also due to this angular shape, it is impossible to remove the refill hence pen is been sold as "use and throw", as one cannot "refill" the pen.

I have this pen and I find it comfortable to use. However, the ink may leak when used and stain the fingers.
The grip can be relaxed and the pen rotated by up to 360 degrees if desired.
