Parker Jotter is a great pen. I am a particularly fond of the all steel versions. Perhaps that absolute intersection of nice enough to keep track of, not a tragedy if it is lost, borrowed or stolen. I ALWAYS back up a fountain pen in court/class/training with either a Parker Jotter or the aforementioned all metal bodied Zebra Sarasa.
The all steel Parker Jotter travels extremely well, both domestically and internationally as a “tactical” pen relative to many others, particularly those designated as “tactical.”
