The K9 Jack in Yellow Bone is a refined take on a classic dogleg slipjoint—its gently contoured handle and yellow jigged bone scales sit between polished stainless integral bolsters and liners for a traditional yet durable look, finished with polished stainless Torx hardware for tidy, serviceable assembly. The dogleg pattern and subtle curves make it comfortable in hand and easy to carry, while the slipjoint mechanism keeps it broadly legal and perfectly suited to everyday tasks.
Under the bolster the blade is a hollow-ground 154CM that wears a belt-satin finish, delivering a clean, low-reflective profile and reliable edge performance; the factory heat treat is in the 58–59 HRC range for a good balance of toughness and edge retention. Together those specs make the K9 Jack a practical, hard-working pocket knife — corrosion-resistant and capable of holding a useful edge for EDC and light field chores, while the quality fit-and-finish gives it a premium feel that suits collectors and users alike.
