They, too, are conducting an experiment, on hundreds (or, maybe by now, thousands) of pianos. These shanks are very consistent and significantly stiffer than those made of wood. I just ordered a set.

I this case, I don't think they were looking for the stiffest results. In fact there are different wall thickness to achieve the desired stiffness from bass to treble.
