I don't remember where I came across this one, which drives me a little bit nuts since it's only been in the last month or so. It's the one at the bottom, shown next to a Rite-Rite "Threadline" pencil:
In my mind, I've got to group this with the "Threadline" family, although mechanically it is nothing of the sort. It more closely resembles the Lipic unbranded pencils that are such a common sight (more on those later), but when I look at the tip, the clip, the profile and the color:
it's definitely all in the family, isn't it?
