I found a Stanley tool someone had given me. It is about three inches long,
and 3/4" in diameter, with a round knurled surface. On one end, there is a
1/8" or so rod projecting. On the other, there is a round hole. When you
press the 1/8" rod on one end, a 3/32 to 1/16" rod comes out the other end
the length of the opposite end. It looks like a ballpoint pen but without
the writing end sticking out. The rod is solid through the body. It looks
like if you were to put it over a finishing nail, you would hit the top end,
and it would countersink the other end, and insure that one could not miss.
Is that what it is?
