John Gray Custom Prototype Gravitron OTF Gravity Knife Copper Vein (3.75" Satin) - Blade HQ

This Gravitron has a "Poppin Copper Vein" handle and an Elmax blade. This John Gray custom prototype isn't unlike a lot of OTF knives out there, similar ergonomics, action, etc., but it's got a key difference. This is a gravity knife. It is opened with either gravity or centripetal force while pressing the button, and closed the same way. Because of this, it's just as fast as a lot of OTFs, but because it has no spring, it's a more reliable mechanism with fewer moving parts. Comes with a carbon fiber pocket clip.
