SHOP CASE KNIVESThe Hinderer XM-18 3.5" Skinny Harpoon Spanto Tri-Way in Stonewash Blue with OD Green G-10 show side is a folding knife built for uncompromising performance, durability, and tactical style. 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 rugged capability. By combining the legendary toughness of the Spanto grind with the added “meat” of the Harpoon topline, this blade delivers a reinforced tip capable of piercing, slicing, and tackling heavy-duty tasks with confidence. Crafted from premium CPM-Magnacut steel, the blade ensures excellent edge retention, corrosion resistance, and versatility, making it a reliable choice for everyday carry, outdoor use, or tactical applications. The stonewash finish enhances durability, minimizes the appearance of wear, and adds a rugged, no-nonsense aesthetic.
This “Skinny” edition preserves all the strength and utility of the standard XM-18 while offering a slimmer, more streamlined profile. Measuring 8.25 inches overall with a 3.5-inch blade and 4.75-inch handle, it balances compact carry with a solid, confident feel in hand. Both the blade and lockside are 0.140 inches thick, providing rigidity without excess weight, while the liner thickness of 0.050 inches adds stability to the frame. The overall handle thickness of 0.452 inches delivers a secure grip for precise or extended use.
The handle features a dual-tone design: the show side is OD Green G-10 for durability and tactical flair, while the lockside is Blue Stonewash titanium, combining strength with visual impact. The Tri-Way pivot system allows users to fine-tune the blade’s action with ball bearings, phosphor bronze washers, or Teflon washers, producing smooth or controlled deployment depending on preference. Every detail, from the reinforced Harpoon Spanto tip to the ergonomically shaped handle, is designed for real-world performance. The stonewash finish reinforces the knife’s rugged look while hiding scratches and wear.
For collectors, tactical operators, and outdoor enthusiasts, the XM-18 3.5" Skinny Harpoon Spanto Tri-Way with dual-tone OD Green G-10 and Blue Stonewash titanium handle delivers unmatched performance, durability, and style. Its combination of premium materials, innovative design, and tactical functionality makes it a standout in any kit or collection. Every edge engineered for strength and precision – the Hinderer XM-18 3.5" Skinny Harpoon Spanto, available at SMKW.
