What is an elastic nib?
An elastic nib is created by cutting out notches on each side of the nib. This customization gives the nib a bounciness similar to a paintbrush. It lends the nib some line variation, but not as much as a flex nib. Out of all the different nib styles, the elastic nib is my absolute favorite.
What pens use osmium?
Osmium alloy is used for fountain pen points, with the alloy called osmiridium when osmium is predominant and iridosmine when iridium is predominant. The most important thing for a fountain pen is that it feels smooth when writing, which requires a suitable resilience and smoothness of the pen tip.
What is a flexible fountain pen nib?
What is a flex nib? Flex nibs are meant to bend when pressure is applied when writing. With that pressure the nib “flexes” or bends, spreading the tines of the nib apart and creating a wider line. This flexing action allows the writer to create varied line widths but the amount of pressure applied.
Why is osmium used in Needles?
But, as was very nicely explained in the letter that came with this fine needle, if you’re going to use a metal needle to get a certain kind of tone, an osmium one will last much longer, and leave fewer shards of metal stuck in the grooves, than will a steel needle.
What is the price of osmium?
around $400
The osmium price per ounce is around $400, while osmiridium has fallen to approximately $21-22 for each gram or osmiridium. Osmium is the densest element known to man, and osmium nanoparticles have substantial surface areas to catalyze reactions.
Are flex nibs smooth?
Flexed Nibs Are Less Smooth However, adding flex actually makes for a less smooth writing experience, as the tines on a flexed nib move independently and are more exposed, tending to catch on the paper.
Is osmium harder than diamond?
researchers have recently broken the myth of diamonds being the hardest substance found on Earth. Researchers from us-based Lawrence Livermore National Laboratory (llnl) have discovered that osmium, a metal, is harder than diamond. It withstands compression better than any other material.
Can osmium be melted?
Physical properties They are also among the highest of all elements. Osmium is unworkable as a metal. It cannot be melted and shaped like most metals.
