I have 3 of those knives. I was unable to find the earlier version with the liners, but I'm still looking. As for the new ones, the ergos are very good. the knife is as solid as Mr. Demko demonstrates in the knifetest videos. The weight is not bad, not a brick by an7y means.
Personally, I would love a model with some higher end materials (CPM-M4 and Carbon Fiber). Yes it would cost more, but that overall design makes it worthwhile.
