Been meaning to get a photo of this one, had it out last night to show my kids. My great-grandfather made it, he was a machinist at US Steel, Johnstown PA. The story is that this was a lunchtime/after hours project, probably sometime in the late 1930's. There's another one, I think my brother has it. Can't remember if it's bigger or smaller though.
Good for calling tiny meetings to order.
Mine can't quite beat that, but I picked up this head on ebay a while back and made a handle for it. I find it strangely handy sometimes.
These 2 little hand planes (and in particular the square) are also surprisingly useful. I bought the Veritas block plane mostly for models, but it even saw some use on a 24" cutting board I made for

last year. I picked up the Jorgensen for one project in particular, and it's proven to be a great $15 buy.
Needed a good way to flatten the inside of a cutout on some cherry, and this guy fit the bill perfectly.
This isn't really a tool, but I'm sure some here will appreciate it. These used to be used mostly (AFAIK) in model RC engines. When NGK discontinued them, other (mostly Chinese) manufacturers filled the void. These originals are very hard to come by nowadays. 1/4" threads and a 5/16" hex
