The pruning blade is among the sharpest regarding SAK blades (Warnclif blade of Minichamp comes close). I don't know why. It is also dangerous for selfwounds, whith that pointy claw design.
A second serrated blade might come handy for plastics, ropes etc. That's my only comblaint whith my Wenger Ranger. It has two blades, so I would prefer the second (security or gutting blade) to be serrated, as Victorinox does.
But, if you prefer it plain, you might get a 130mm Delemont. And you can make a point to the gutting blade yourself, in order to have a big pruning blade, as they should be (and as Opinel makes them).
