Hey!.....I have not seen one shaped quite like that in some time now.
I LIKE it. I'm going to steal that shape for my next slimline..........I'm always looking for ways to give pens a little more "meat" to them without making them seem too bulbous or unwieldy.
Yours works well. I like the understated way you made the cuts near the nib, and the middle looks good too.
Too bad about the cracking. Bummer.
