It is not normal IMO but not that unexpected. None of my Pruners do this but there is not much play allowed there and I can see how it happen. When the pruning blade is slowly closing you should see its tip being about equally spaced between the alox scale and the main blade.
Is the main blade flush (from tang to tip) when closed with the scale on the other side? It may happen that your Pruner got a less twisted or heavier main blade, like the Solo has, not leaving sufficient room for the pruning blade.
Do you have a photo of your SAK with both blades closed, from above (spines)?
