I got this for Christmas and I’ve carried it in my pocket since. I love it. I always carry an SAK and I like carrying a light and a pen. But I hate 2 things: stuff bouncing and rattling around in my pocket. And things clipped on my pocket (knives/flashlights,etc) so I end up not carrying a light and a pen often times. this thing makes carry perfect. And no noise when walking. brand is dioderio which I had never heard of. The SAK I already had. The light and pen were part of the gift. I don’t know the name of the pen. Looks like pokka? It is plastic. It appears to be the same size as a Fisher bullet pen so that might fit as well. love it.
