The Heretic Jinn began as Heretic's first ever slip joint, a compact gentleman's folder built to carry anywhere without drawing attention. It has since grown into a family of button lock flippers and side opening automatics, and at 0.382 inch thick it is still the slimmest knife in the Heretic Knives lineup.
The Jinn Manual keeps the original's size but trades the slip joint for a button lock flipper, so the blade snaps open with a flick and stays locked until you press the button. It is a natural fit for office and dress carry, and it sits among our folding knives for buyers who want a lock without a large knife.
The Jinn Auto is a push button side opener built from the ground up for this frame, using custom flat coil springs and a proprietary bearing system that were new to Heretic, not a larger auto scaled down. It fires fast, locks with no play, and adds a refined option to our automatic knives. For a larger Heretic button lock, compare the Heretic Pariah.
Every current Jinn runs a 3 inch CPM MagnaCut wharncliffe on thin 0.09 inch stock, 6.75 inches open and 3.75 inches closed at about 2 to 2.25 ounces. The straight edge and fine point make it a precise slicer for boxes, letters, and food, and MagnaCut keeps it sharp and rust free. Our comparison of every major knife steel explains why.
Chassis options include carbon fiber, glow carbon fiber, and aluminum in black, OD green, black topo, and blizzardworn. Blades come in DLC, bronze, two tone, battleworn, metallic green and teal, topographic DLC, and hand painted black and white cel shading. A reversible titanium clip carries tip up on either side, and every Jinn is made in the USA.
