SHOP CASE KNIVESThe Hinderer XM-18 3.5" Skinny Harpoon Spanto Tri-Way in Working Finish with Coyote G-10 is a folding knife built for serious performance and uncompromising durability. Among the most aggressive of all 3.5-inch XM-18 blade grinds, the Harpoon Spanto elevates the iconic XM-18 design to a new level of toughness and tactical style. By combining the legendary strength of the Spanto grind with the added “meat” of the Harpoon topline, this blade delivers a reinforced tip capable of piercing, slicing, and handling heavy-duty tasks with confidence. The CPM-Magnacut steel blade offers excellent edge retention and corrosion resistance, making it a versatile tool that performs in any environment.
The “Skinny” edition preserves all the toughness and utility of the standard XM-18 while offering a slightly slimmer, more agile profile. Measuring 8.25 inches overall with a 3.5-inch blade and a 4.75-inch handle, this knife balances compact carry with a solid, confident feel in the hand. Both the blade and lockside measure 0.140 inches thick, providing rigidity without unnecessary weight, while the liner thickness of 0.050 inches adds stability and reliability to the frame. The overall handle thickness of 0.452 inches ensures a comfortable grip during precise work or extended use.
The handle is crafted from Coyote G-10, paired with a titanium lockside finished in working stonewash, delivering both strength and visual appeal. The Tri-Way pivot system allows users to customize the action using ball bearings, phosphor bronze washers, or Teflon washers, providing a smooth or controlled deployment based on preference. Every detail, from the reinforced tip to the ergonomically shaped handle, has been engineered for maximum performance. The working finish adds a rugged, no-nonsense look while helping to mask scratches and wear, making the knife ideal for tactical use, EDC, or outdoor applications.
For collectors, professionals, or everyday users who demand reliability, the XM-18 3.5" Skinny Harpoon Spanto Tri-Way delivers high-end performance, tactical aesthetics, and the proven durability of a Hinderer knife. Its combination of premium materials, intelligent design, and rugged functionality makes it a standout choice for any kit. Built tough, engineered to perform – the Hinderer XM-18 3.5" Skinny Harpoon Spanto is available at SMKW.
