Here's a nifty little gadget you don't often see, at least I don't. It's an oil pen I found among my dad's gun tuning tools. When you press the tip against the item to be oiled, it backs into the shaft, releasing the oil. I also have an X-acto knife that is a nice match to this one.

That's neat! I can see uses for it.

I have seen new ones you squeeze, but they don't have the valve action that one does, really nice.
