The Ponos have a dual-action truss rod, in case you should ever need to adjust the neck relief (not the action, though a truss rod adjustment may help temporarily with that as well). I've not yet had to adjust the relief on any of my Ponos or Kalas, but I have had relief problems with a couple of other ukes, so the truss rod feature may pay off some day with my Ponos.
The Kala SMHB also has an adjustable truss rod.
