That bottom one is nice. I don't like straight blades so it is the version that suits me.I kinda went down the rabbit hole with Demko Shark Lock knives, I now have 3 (I THINK I'm done now!) - I've posted the top 2 before, but...
Whatever!
Top is the grail - USA made S45VN steel Sharkfoot blade (awesome), aftermarket USA made raw aluminum Original GOAT scales and Skiff ceramic bearings.
Middle was my first purchase - Sharkfoot blade in AUS10A steel (not that special, but OK) and aftermarket RGT canvas Micarta scales.
Bottom is my newest - the smaller Shark Cub with the Slicer blade profile (my fave!) in CPM 20CV Steel (also awesome) with the factory black aluminum scales.
The Shark lock is incredibly fidgety - SO fun to open and close, annoys all the womenfolk within range of the snickety-snick noises!
I gotta admit that the newest, smallest, and (just barely) cheapest Shark Cub is the BEST for EDC - perfect size, and very slim profile.
