I'm glad he posted the video. One thing he didn't mention that is striking to me is how high his hand is on the page, essentially resting above the line he is writing, with his thumb parallel to the line. Whereas as a right-hander, my hand is essentially centered on the line, with my thumb at a 45 degree angle to the line.
Do most left-handers learn to hold their pen/pencil like that? If not I imagine it would be quite a transition to adapt to as all the motions are rotated - the portion of the stroke previously done by moving fingers in and out would instead be done by moving side to side, and vice-versa.
Edit: Or from trying it, I guess you could just write as normal and end up with everything italic/slanted.
From what I've read, lefties are typically classified into "over-writers", "side-writers", and "under-writers". That video caught my attention too, as it shows pretty clearly that he's an over-writer.
I myself am probably somewhere in between an over-writer and a side-writer lefty, edging slightly closer to an over-writer. Maybe a 20 degree angle to the line as my thumb wraps around my other fingers?
I've never found a fountain pen that I've liked because every time I've tried one, I ended up tearing the paper as I go as I'm essentially pushing the nib across the page and so the nib snags on the paper, digs in, and makes little holes. And I left pencils behind as soon as I could in school because every day I'd come home with the side of my left hand silvered with graphite.
These days, my preference is a Pentel EnerGel, a Uniball Signo, or a Pilot G-2 (i.e., gel pens like the article mentions). They can write easily without much force and dry quickly enough so that my hand doesn't smudge. For my daily pocket carry, I've also learned that I always want the capped variants rather the click kind, or else I'll end up with stained inner pockets and scribbles on my thigh. This makes the G-2s nice for home and desk use, but not for daily carry.
(And though the article suggests using cursive and not getting hung up on legibility, somewhere back in grade or middle school I switched to using either print style, or an engineering-hand-like small caps style, depending on mood. Both in the interest of legibility, despite my left-handedness.)
