The cap of this pen features a very nice knurled section at the top to aid in uncapping the pen, and triple start threads to make it easier to cap the pen. As well as perhaps the sturdiest pocket clip ever on a fountain pen. With that being said I would caution you about clipping this pen to expensive dress shirt pockets as it could damage the shirt if not done carefully.
The barrel of this pen tapers from the threads down, and is a very comfortable length for about 90% of people. Because this pen doesn't post, if you have very large hands this pen could be a little short for you. In which case I might suggest the Ink model which also doesn't post but is longer, or the Decograph which does post.The grip section is very nice with a slight flair at the end to keep your hand from slipping down the pen.
This pen features a #5 nib that is available in ef-1.1 in steel, and several options in gold and titanium. The medium nib I have, works great and flows consistently with no hard starts or skipping. The extra fine nib works well once it gets going, but dries out rather quickly and writes dryly as well. It accepts both standard international short and long cartridges, as well as the Schmidt standard international converter (which comes with the pen)for use with bottled ink.
Over all this is a very solid U.S.A made, edc type fountain pen, that can take a beating and still function great. Variety in colors available, as well as two different materials like copper (seen above) and Brass, and the multitude of nib choices make this pen outstanding. All of Karas Kustoms pens are super high quality and made to last.
