As I write this, the quantity of wotsits guesses is a trifle low. I think I can feel a decision about this blog's future coming on, because I'm not convinced any of us are having any fun.
Anyway, the answer is... (insert drumroll here) A nib holder.
In what I believe is greenheart. Remind me not to use greenheart again - I sharpened the roughing gouge four times to complete this, which is ridiculous even allowing for my lack of turning competence.
You might recall I posted about making an effort to improve my handwriting back in June, and one of the ways to do that is to slow down. Trust me, nothing slows you down like using a dip pen. But I increasingly found the number of nibs I wanted ready to use far outweighed the number of holders I already had to hand - not helped by lucking upon a small selection of them at the car boot. And call me a tight-fisted woodworker, if you will (and heaven knows, it is a bit of a trait amongst the wood torturing fraternity), but I resented the thought of sending someone money for a stick that I had the means to make myself. So I have. A few times.
Front to back is the greenheart, pink ivory, muhuhu, and muhuhu/rosewood with a annoying decorative ring from the equally annoying pen turning kit I liberated the brass tube from to make the actual nib holder.
It's an on-going experimental thing of trying new shapes and sizes, and at least it's making use of some of those tiny pieces I hoard in my scrap box. Rather disappointingly it's seeming increasing like I should simply copy one of the plastic holders I already have, as it just seems to suit me. Figures.
For nib holders that are infinitely better turned and a lot more eye-catching, go Googling for "oblique pen holders". There are some real stunners out there.
Of course, after all that, it's too bad the handwriting hasn't improved more; my slopes are more varied than the answers to a "Which angle should I use for dovetails?" Hey ho.
