Good steel is as good as good gold....accent on good.
Gold is more expensive. Lots of folks think gold is better....some because it's gold.....others that they must have done better work on the nib, because it's gold.
Osmia/O-F-C or Geha, the gold nibs are equal to the steel ones. Something I didn't know when I was chasing Osmia pens....or I could have gotten more of them.
I knew the Geha steel nibs were as good as the gold....I just didn't run into enough on the 790's. I'll have to look for steel on the earlier '50's ones.
When it comes to nails....a steel nail is much better than a gold nail outside of bling, because of all the inks you can buy when you are wise and get steel.
I do have to admit the gold Esterbrook nibs are much better than the steel.
Wisdom of the Founders, and their check and balances system is more a wonder than I thought.
Due to Mauricio's improved definition of Super-flex, I try not use the term Easy Full Flex, but fail...sigh.
Semi-flex is an “almost” flex; not a ‘flex’ nib. It is great for regular writing with a touch of flair. It can give you some fancy; but it is not made for real fancy writing. For bit more of that get a maxi-semi-flex. Both spread tines 3X. Those are not "Flex" nibs.
Wider than Normal does not exist. Wider than Japanese does. Every company has it's very own standard + slop/tolerance. Developed from the users of it's pens and inks only; not the users or inks of other companies pens. The size you grind a nib to, is your standard only. Paper and ink matter to nib width. Thank god for 1/2 sizes or it would be boring.
