I made the tool I use from a piece of 1/16 inch brass rod. Cut it about 6 inches long, bent over one end about 1 inch from the end to make a handle, ground the other end to a screwdriver point. To insulate just used heat shrink a little above the end, wrapped the handle end with black plastic electrical tape. It's non-magnetic and works great.

So even though iron (ferrous metal) is not used, brass will also detune an inductor.
