I bought one of the tiny ones. I'll try to remember to get a pic of it with it's bigger brother, and a peanut to compare.
I like the larger one, and it will sit around with me when I'm home, but I rarely take it out of the house. It is a bit loose, and I'm afraid of it opening in my pocket.
I had to take a ceramic rod to mine, to fix some finish issues, though they were minor.
Mine was a gift from a generous gentleman who sometimes hangs around here, and has a colorful name with some musical undertones.
