I was planning to write a review of my now 3 week old Signum Nova. However, I loaned it to a friend of mine and he reviewed it on his blog.
I certainly could not do a better review, so I'm posting it here.
What i can do, is tell you that I like the pen so well that i have ordered 2 more Signum pens with 18k nibs. Another Nova with a F nib and a Carene with a M nib.
