New to the forum. I just got a Kapara and LOVE IT!!! Action, ergos, back spacer, clip, materials including the blade steel. I looked at the designer's site and his "Redback". He uses RWL34 steel, which is very similar to S30V. Outside of not having a sharpening choil, I think the Kapara was manufactured to remain as true to the original design as possible. Kudos to Spyderco, Sal and Eric, if that's the case. Also, CPM S30V may not be exotic, but it's stainless and a solid performer.
