He carries AA batteries to the top of the carpeted stairway, then rolls them down and tries to catch them as they roll. He rolls 6.8mm cartridges on my desk and now found an expanded .40S&W Black Talon and using it as a soccer ball.

I am trying to get a good photo of a pair of blades. I put oil on the metal and wiped off the excess with a rag. Looked fine to the eye but not so fine to the camera. Any suggestions on getting an evenly oiled surface?
