I have 4: 2 Gen 3 3" slicers (one flipper, one non flipper) and 2 Gen 4 3.5" (one spanto, one slicer). I've added the full Ti scale option to the 3.5" Slicer and it is my preferred Hinderer.
That being said, I think they are overpriced and under-functioning knives, more art pieces to me. The fact that I bought them is something I regret along with most of my other tacticool knife purchases of the last few years (recent realization of course too late to save me).
