I've had this pencil for quite a few years now, and I actually never really liked it very much. untill I recently discovered that the way it is sharpened, can improve it's performance considerably.
I mostly bought it because of the lovely design. It's extremely tapered, especially in the front, where it gets too narrow to hold. So you automatically hold it further down the barrel, that's why it is a great sketching pencil. It has a nice, large eraser under the twist cap (yes, it has a twist-action mechanism!) It has a substantial wheight, mostly because of the metal parts. You would think the mechanism is also made out of metal, but unfortunately it isn't, though it still feels very sturdy. My guess, they probably used plastic because it would become too heavy if they used more metal!
