Well-built, writes well, looks professional
I have two everyday ball-point pens that I've used in the past: an all metal Parker Jotter and a Fisher Space Pen. I like the classy look of the Jotter, but the ink isn't that smooth, and the tapered edge can get tiring after longer writing sessions. Same with the Space Pen, the tapered edge is tiring. The Fisher Space pen does have really smooth feeling ink though (but the lines aren't as clean.) \

This Fisher basically can replace both of those pens. It has the classy professional all steel look (the clicker has been updated to be steel too), it has a cylindrical knurled grip so your fingers won't get tired, and the ink is pretty decent. It also has the capability of taking in Space Pen refills with a slight mod (just remove the plastic holder in the tip). Additionally, even though it's all metal, it still feels light enough that it's not tiresome. \

The only downside I will say is that I wish it could take in gel refills or felt tip refills somehow, I love the barrel/housing that much.
