This is the tool that is use when I fix bent nibs on Fountain pens! The big silver bloc of steel. I thought you would get a kick out of seeing one of my tools. Very few of these particular tools actually exist as they are so expensive. I just bought mine and it was just delivered in today's mail, 5-21-2012. It came all the way from the UK. Some people just throw the bent nibs away. Why do that when you can send them to people like me to straighten them out and send them back to you to save your fountain pen, especially if it has sentimental value. The tool with the blue handle is called the burnisher and that is what you use to "rub" or "roll" the nib rinkles out with on the bloc.
Hope you liked seeing one of my tools for fixing Fountain pen nibs. :-)
