I was browsing through "What`s In Your Pocket Today" and I`ve noticed Vacumatic`s pen post about his pens a "Parker Duofold Streamline with lots of flex and an Onoto K3 with semi flex." It got me thinking and yes it can be dangerous. For the most part I like nibs that are rigid/straight forward and gets the job done. I`m often scribbling down my notes and I also write in my personal daily journal and even with nibs that do flex I don`t intentionally write with much line variations. So what are your thoughts on this to flex or not to flex? Yes some flexing can add some zest to your writing but what about just getting things just written down and be done?
