The Nakaya Decapod in AO tamenuri.

It took me a long time between liking the Decapod and getting the Decapod. Much of that hesitation had to do with the initial discomfort my hand felt when I tried one for the first time. The facets were distracting.

Nakaya Decapod

Misgivings quieted when I saw the AO tamenuri finish. It was like arguing myself into a pair of wedges. “My ankles will snap. But those shoes are sooooo pretty!” Familiarity breeds preference, after all.

Decapod, uncapped
The step from the barrel to the section is similar to other Nakaya models, but the taper of the barrel makes it more obvious.
Your inner obsessive-compulsive will be happy to know there are only two ways to align the cap to the barrel so the facets line up as they should: nib up or feed up, centered with the clip. Mine is feed up.

This Decapod's tiny conceit is its music nib, ground to have more line variation. The monotone gold matches the clip.

Not too wet, not too dry, just right. This is a writing sample in a Midori Traveler 014 refill.
Other pen makers offer faceted pens. From a practical standpoint, these pens give you more feedback when being held, so can encourage a more mindful grip; and when you need to pause and put them down, they don't roll off the table.
From a non-practical standpoint, they're just plain pretty.
