Description
The Hinderer XM-18 3.5 BPU #1207 Liner Lock Harpoon Spanto is a rare configuration from Rick Hinderer Knives, combining the iconic XM-18 platform with the unique Liner Lock construction and Hinderer’s exclusive BPU (Battlefield Pick Up) finish. Unlike the traditional XM-18 frame lock design, this version offers a more refined and classic folding knife aesthetic while maintaining Hinderer’s legendary durability and engineering.
With an overall length of approximately 21 cm, this model features a MagnaCut Harpoon Spanto blade with BPU finish. The Harpoon Spanto is one of the most recognizable and highly sought-after blade profiles in the Hinderer lineup, combining the reinforced Spanto tip design with the distinctive raised harpoon-style spine for excellent strength, piercing capability, and aggressive visual appeal.
The handle features a military green G10 scale and utilizes a traditional Liner Lock system. The independent titanium locking liner is hidden beneath the G10 handle scale, creating a cleaner side profile without an exposed frame lock bar. This design gives the knife a more classic gentleman’s folding knife appearance while reducing overall weight and improving carry comfort.
The Liner Lock XM-18 BPU models were produced in extremely limited quantities, making them a highly desirable configuration among Hinderer collectors. This rare combination of MagnaCut steel, Harpoon Spanto blade geometry, BPU treatment, and unique liner lock construction represents one of the more uncommon variations within the XM-18 family.
The XM-18 3.5 BPU #1207 Liner Lock Harpoon Spanto perfectly balances Hinderer’s rugged tactical heritage with a more refined and traditional design language, making it an excellent collectible piece for enthusiasts seeking a rare XM-18 configuration.
