I like this pen because of the deep pocket clip, I am kind of discreet, and more low-key” DIPLOMATIC ARTIST:) I am a freehand, graphic artist, mainly using ink pens’ but most of the time I like a mechanical pencil” for what I call a shadow image or a pulmonary sketch” and that’s why I like this ink pen:) it’s rugged interchangeable capabilities(IN MY PERSONAL RETROFIT) increases the diameter of the barrel and positive control grip-finger areas, because I am a heavy-handed artist, and I move with extreme precision and accuracy. Or mostly deliberate with concentrated focused.(I’m must keep my hand close to the nib or point of the edge of the pen to see exactly where the ink or lead is contacting the paper.(didn’t mean to give a convoluted explanation.) suggestion!!? can you make a screw on extended barrel width with ridges-lines on them?🫡🇺🇸‼️ thanks for the Veterans discount.
