Originally, we thought the bolted on pocket clip meant this was a Karas Kustoms pen. However, it hasn't any imprints and the wrong nib. The Admok nib might lead one to believe it was an Admok pen, but we looked up the brand and didn't see any steel pens such as this one. Whatever it is, it is a very solid steel pen that comes with a converter. You will write an extra-fine line with some feedback with its steel nib. 11cm capped.
