14 K is so known......there are vintage 18 K that are good, but from what I read here, the modern 18K is not so durable...it will bend and stay bent when stressed or over stressed, where a 14K semi-flex nib will not.
That is why I was so interested in how wide the nib had been pushed.
Some folks come from nails and press a regular flex....and think because the tines both bend and spread , think regular flex is semi-flex...they have heard of.
The 3 X tine set max, are regular flex, which when well mashed will go to 3 X....not that someone would really want to write like that....way too much work. But is a springy nib, a nice ride.
Semi-flex takes half of that pressure.....In I was still ham fisted, I spent some three months getting a lighter hand and not maxing the nib all the time. A Pelikan 140 OB.
Which was good, in the next 'semi-flex' I got wasn't, it was a maxi 400NN OF; but my Hand was much lighter, so I didn't discover it was maxi...until later when I invented the term, due to my most flexible Maxi nib, a Rupp nib.
Maxi-semi-flex, half of semi-flex or 1/4th the pressure needed to mash a regular flex to 3 X.
Well one has to have a regular flex to tell if the new pen is semi-flex....has to have semi-flex to tell if a new pen is maxi-semi-flex.....because I think trying to go from regular flex to Maxi would be misleading. In one would think the maxi is semi-flex and the normal semi-flex not springy enough....or a good enough semi-flex.
Grumbling about second class semi-flex nibs.
