The Jack Wolf Primo Jack takes the oldest silhouette in the folding knife world, the barlow, and gives it a lock, bearings, and a front flipper without losing a drop of its soul. Jack Wolf Knives kept the hallmarks that define the pattern, the teardrop handle and clip point blade, then rebuilt everything underneath to modern standards. Deployment happens two ways: a quick flick of the front flipper tab, or the slow, deliberate pull of the fuller style nail nick for those who like their barlows opened the old way.
The 3.26 inch clip point runs Crucible CPM S90V at 60-61 HRC with a hollow grind, finished in hand rubbed satin on the traditional handle materials and belt satin on the modern ones. That edge holds through weeks of daily carry, a working advantage no historical barlow steel could offer. See how S90V earns its reputation in our guide to every major knife steel compared.
The frame lock is built into fluted, dark blasted 6AL/4V titanium bolsters machined integral with the liners, and the blade glides on ceramic bearings with a titanium backspacer closing the spine. A removable tip up pocket clip ships alongside a recess plug for a seamless clipless carry, a detail that says everything about how this knife was thought through. Our knife lock types explained guide covers where frame locks sit in the locking family.
At 4.38 inches closed and 2.9 ounces, the Primo Jack carries slim and draws attention anyway, with scale runs spanning rosewood, linen micarta, bone, Kirinite, and Fat Carbon depending on the release. Each run is limited and unrepeated, so the configuration that catches your eye is the one to take home. Find the rest of the family in our Jack Wolf Knives collection.
