Caran d’Ache’s Grafcube is a formidable chunk of graphite. You can letter with it, draw with it, or conceal it in your fist for added punching power.
(Pardon the dirty fingers.)
The graphite is dense. I did a test run to loosen my shoulder, because big letters call for big arm movements.
The Grafcube lets you rediscover calligraphy with your body. Wielding it feels like dancing.
I did this in two minutes.
Then I decided to ink all over it, using Noodler’s X Feather with a bamboo pen. More dancing.
Get a Grafcube and sheets of A3 paper, and just let loose. It’s a happy thing.
