A handy tool that I saw on Amazon and picked up a few years ago
A drill and tap guide.
With a V notch on the bottom to sit square on round or corner stock. So, I am sure you all can see the uses, but when you need to tap and or drill into stock in the field and want it to be square, this handy tool will get you there! Made by Big Gator tools, I paid $22 and it has come in very useful around the house. I could have used it a lot in the field too.
