Hinderer 3.5 XM-18 Skinny Harpoon Spanto Tri-Way Working Finish Black G-10 KXM35SKHSTWWFBK

The Hinderer XM-18 3.5" Skinny Harpoon Spanto Tri-Way in Working Finish with Black G-10 is a folding knife built for 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 with a reinforced tip and robust profile. By combining the legendary toughness of the Spanto grind with the added “meat” of the Harpoon topline, this blade delivers exceptional piercing, slicing, and utility capabilities. Crafted from premium CPM-Magnacut steel, the blade offers excellent edge retention, corrosion resistance, and versatility, making it ideal for everyday carry, outdoor tasks, or demanding tactical situations.

The “Skinny” edition maintains all the durability and cutting performance of the full-size XM-18 while offering a slimmer, more agile profile. Measuring 8.25 inches overall with a 3.5-inch blade and a 4.75-inch handle, it provides a compact, balanced feel without sacrificing strength. Both the blade and lockside measure 0.140 inches thick, giving rigidity and strength for heavy-duty tasks, while the liner thickness of 0.050 inches adds stability and reliability to the frame. The handle thickness of 0.452 inches ensures a secure grip, allowing for controlled cutting in any scenario. 

The handle is constructed from black G-10 paired with a titanium lockside finished in working finish, combining toughness with a sleek, tactical appearance. The Tri-Way pivot system allows users to adjust the blade action using ball bearings, phosphor bronze washers, or Teflon washers, offering either smooth or controlled deployment to suit personal preference. Every aspect of the knife—from the reinforced Harpoon Spanto tip to the ergonomic handle—is engineered for practical, real-world performance. The working finish reduces glare, hides wear, and adds a rugged aesthetic that matches the knife’s hard-use capabilities.

For collectors, outdoor enthusiasts, or professionals who need a reliable, high-performance folding knife, the XM-18 3.5" Skinny Harpoon Spanto Tri-Way delivers unmatched durability, precision, and style. Its combination of premium materials, thoughtful design, and tactical functionality makes it a standout in any kit or collection. Built for hard use and everyday carry – the Hinderer XM-18 3.5" Skinny Harpoon Spanto is available at SMKW.
