that back in the '60's I
had a slide rule that was made of laminated bamboo. Sorry for the

It was probably a Sun-Hemmi, made in Japan. In my opinion those worked
better than K & E or Dietzgen. which were made of wood. The fact that the
grain of bamboo runs perfectly parallel to its axis provides an unbeatable
sliding surface. I once lost a whole grade point in a chemistry final
because it was raining that day, and my sliderule (not bamboo) was sticking.
