What is a flex nib?
Flex nibs are meant to bend when pressure is applied when writing. With that pressure the nib "flexes" or bends, spreading the tines of the nib apart and creating a wider line. This flexing action allows the writer to create varied line widths but the amount of pressure applied.
What is the difference between flex nibs?
Flex nibs are not all created equal. Some flex nibs have little flex such as a soft nib which has a spongy feel with little line variation. Others are made to flex more to easily give more line variation.
