The spiral-clasp idea journal is a simple creation that elicits a 'wow' from people seeing me casually taking it out and writing in it. Using brass rod, a few springs, and a screw/nut combo, four arms reach out and hold the corners of the book tightly. A fifth arm grabs the pen and opens the clasps as the pen is removed.

This was the product of a day's worth of work after about a week of pondering on a cool way to keep a book closed. This turned out to be the most practical and elegant. I've had it for a few years now (always near me) and it has held up quite well.

Here's a detail of the pen arm - it hooks around the pen so you grab it when removing it.

The corner clasps grip the cover of the book. The ones on the spine don't really do anything but they complete the look.

The center ring is fixed to a nut in the center. A screw and another nut hold the whole thing to the book.
