I wonder what the author thinks steampunk means

Right- that's really just a version of a worm pick. I use similar tools (including a mouth pipette... remember kids, in chemistry: don't pipette by mouth, in biology: oops I think I just inhaled something!) working with tardigrade. If it was steampunk there would be some sort of goggles, leather, gears, and a tincture of laudunum.
