An old colleague was gifted one of these years ago and it always stuck in my mind. Had a career event worth celebrating and picked up one of my own. Just as solid, unique, and thoughtfully designed as I remembered. Great tactile cap engagement and fun to play with. Finishes and appointments are top notch, if a tad on the sharp side on clip edges. Perfect length and balance, writes like a dream. Now I need to find a new grail.
Although the cap has a patented attachment system, it is not particularly tight.
The back end of the pen may unscrew if/when you attach the cap to it and then take the cap off
