The Jack Wolf K9 Jack takes the classic dogleg jack pattern and gives it the full modern traditional treatment the brand is known for. The soft bend in the handle is the whole point of a dogleg: it settles the knife into the hand naturally, indexing the grip without a single aggressive line. Jack Wolf Knives has run the K9 across multiple releases, from early premium builds in Bohler M390 to the current generation in 154CM, offered in both Ultralight and Steel Series trims so the same beloved silhouette fits two different pockets and price points.
The current K9 Jack runs a hollow ground spear point in 154CM at 58-59 HRC with a belt satin finish, a full bellied blade shape under 3 inches that slices far above its size. It opens with a traditional nail nick against a firm pull and settles into a crisp half stop, exactly the deliberate action slipjoint people carry these knives for.

The Ultralight Series swaps bolstered construction for integral G-10 and layered scale materials like canvas micarta over colored G-10 liners, bringing the whole knife in under two ounces with a matching paracord snake knot lanyard. The Steel Series dresses the same pattern in traditional materials, sawcut Richlite and jigged bone among them, over bolstered construction with polished hardware. Both trims close under 3.8 inches and disappear into a pocket or slip.
The K9 Jack is the kind of knife that converts people to traditionals: light enough to forget, curved enough to feel custom, and finished to the standard that built the Jack Wolf name. Variants are limited runs that sell through and stay gone, so the configuration in front of you is the one to buy. Browse the rest of the lineup in our Jack Wolf Knives collection.
