Manually Adjusted Ultra Flex Nibs

The last few months we have been working on perfecting a manual adjustment to reduce the amount of pressure required to flex our FPR flex nibs.  This half-moon cutout from the shoulders of these nibs was inspired by various "ease my flex" experiments on www.FountainPenNetwork.com.  Each of these new "Ultra Flex" nibs has been manually ground and polished so as to reduce flex resistance while maintaining the integrity of the nib against tine springing.  Check them out!!!
