This is my first attempt at a modified pentel Pencil (well, actually it's the second attempt but we won't discuss the first). I have been wanting to make a Pentel Pencil for a coworker that uses one daily. He likes the 0.7mm because he is a little heavy handed. I figured a 4130 chromoly would do the trick. I still have to tune up the finish a little, but couldn't wait to share it. Turns out he is retiring in a couple of months, so this will be his retirement gift from me.
