I was looking at these too! Its on my list of potential candidates.
Question for you guys. I had a buddy who years ago, had a Jim Dunlap carbon fiber slip joint. It felt really nice but I have no idea on the quality. Here is what I am talking about:
https://www.knifeology.com/product-page/jim-dunlap-gentleman-s-folders (also, if anyone knows if that website is a good one to order from, they are the only ones I could find with those in-stock).
I think I am going to order one of those Lionsteel's from Collectorknives and also a another one. I don't know why I thought I would buy less getting into these slip joints
