Excellent quality pen. Great writer too thanks to the Schmidt 900 M ink cartridge included with pen.
Very nice pen, feels good in hand. Writes well and AAA+++ on figet factor! Added a drop of WD-40 to bolt action to smooth it out a bit. I have the twin to this pen by WE in titanium... Super cool look with lots of comments from people. But its a bit heavy, this one is Aluminum and feels about average in weight for quality pen. Sides have a nice tactile feel and has a nice grip but not to grippy. Priced much less that the WE and well worth the money. Tip: Keep pen closed when putting it away or storing in pocket, if dropped on ball end of refill it will never write the same again, and it will start leaking/blobbing ink. Learned the hard way.
It's my first bolt-action pen, and is holding up well to being used in an Ag/Commercial tire service job. I've had no issues with the finish wearing off or the action sticking. The only issue I had was during sub-zero temperatures, the cartridge would take a couple scribbles to start working. However, nothing works well in -30F weather, so I can't fault the pen too much.
I don't believe this pen can break auto glass without losing a finger but it's a fun pen that writes well and doesn't roll on a flat surface.
