This is one of my favorite fidget knives... The pivot uses ball bearings as I recall, & opened me up to the possibility of looking for fidget knives in the Boker Plus line. And there are definitely others worthy of fidgeting -- though they've had some failures as well. It was because of this knife that I discovered the Boker Plus Lateralus -- one of my all-time favorite fidget knives. And next on my list is the Boker Plus Caracal linerlock flipper folder with Coyote Tan scales & a coated D2 blade.
