Ahhh! I'd say puzzle solved - perhaps my Ma was recycling one from her
days in college as a bio student and working in various labs - or perhaps
one from her Dad's gen. practitioners office! It had a solid cast and
turned brass point like a plumbbob and I thought the sharp edge of the
blade was inward and would retract into the point, but I may be wrong as
most of the blade was gone.
