Serial Number 001: The First of Its Kind
Serial numbers don’t get better than this. This is the JKK Customs Clever Gurl XL, serial #001 — the very first of the model. Moreover, it comes from one of the most exciting young makers in American custom knives.
Jen Lint and JKK Customs
Jen Lint is the Gainesville, Georgia-based knifemaker behind JKK Customs. She builds high-end, small-batch knives entirely by hand in the USA. Furthermore, she has become famous for her signature rock-grind finishes and bold, unconventional designs.
Her work runs in tiny numbers — one-offs and micro-batches that sell fast and rarely resurface. Models like The Beast, Predator, and Cleavage built her following. Consequently, collectors now watch every JKK release closely. She stands among the rising names in our custom knifemaking world, and early serial numbers like this one are exactly how smart collectors get ahead of the most valuable custom knifemakers of tomorrow.
The Clever Gurl XL, In Hand
This Clever Gurl XL is offered pre-owned in mint condition. It opens to a commanding 8 inches overall. The 4-inch blade is CPM MagnaCut — today’s benchmark super steel for toughness, edge retention, and stain resistance.
The blade finish is the showstopper. Jen’s signature rocked, hammered-texture grind ripples down the blade in bold scallops. Meanwhile, matching scalloped spine work adds grip and drama. A machined thumb slot opens the blade smoothly on demand.
The frame is blue stonewashed titanium with a solid frame lock. Set into the show side is a vivid 80s camo carbon fiber inlay. Neon greens, oranges, reds, and blues streak through black carbon like a retro fever dream. As a result, no two angles of this knife look the same.
The details finish it off. Blue and bronze anodized titanium hardware surrounds a custom gear-style pivot collar. A faceted blue-and-bronze backspacer runs the spine. Additionally, a bronze anodized titanium clip carries it deep and secure. Among folding knives, this one is impossible to mistake for anything else.
Documented, Complete, and Verified
This example includes its JKK Customs zippered pouch, maker patch, and hand-filled COA card. The card documents the model, serial #001, September 2025 build date, rocked MagnaCut blade, and 80s inlay titanium handle. That documentation anchors the provenance collectors expect from us on every piece.
We inspect and conservatively grade every knife in hand. Therefore, what you see in our photos is exactly what ships. This one presents flawlessly — a mint, first-serial custom from a maker on the rise.
