Recently I've returned to using 2mm mechanical pencils to get a more organic feel in my sketches. I love the sharp point of a 0.5 mm pencil, but it was just too rigid for me.
But me being me, I search near and far for the writing utensil best suited for me. This also means that form and function must be on the same level. In the case of my everyday carry pen, I searched for about 2 years before landing happily on the Karas Kustoms Retrakt with a Parker Pen fine ball point tip refill. The aesthetics of the pen are beautiful and the function of the Parker refill suit my writing and sketching needs perfectly.
I'm undergoing the same process at the moment with my pencil. Currently I'm using a Staedtler 2mm pencil and functionality wise, it works fine. The aesthetics portion however, are just so so in my opinion. But as always, Kickstarter seems to save the day. I discovered the Penxo today and immediately backed the project! It is such a beautiful and simple writing utensil an the perfect mix of beauty and utility. I just hope that when I receive my very own Penxo, it will hold up to it's presumed glory.
