I've long had an affection for really fine writing instruments. My wife would call it an obsession, but... [embarassed]
I use pencils almost exclusively for my writing chores, and the collection came along from about 25 years of my having to do technical drawings and schematics for my real job. These two photos show the majority of my collection. A mix of .3, .5, .7, and .9 lead.
Not even going to mention the cost of some of these. At the end of the day they all do the same thing, but sometimes it is just really nice to hold a quality instrument in your hand. This thread appearing on FOG is very apropos because we could all settle for using entry level power tools from Ace Hardware, but we don't.
Suffice to say that most of these are never used outside of my office, let alone in my shop!
