Excellent knife and excellent service from Knives Plus! 03/15/2026
By GREG WILLIAMS
First off, great experience with Knives Plus. Fast shipping, good communication, and the knife arrived exactly as described and well packaged. Always reassuring when buying a knife in this price range.

I carried an XM-18 3.5 (Gen 4) for well over a decade, so I’m very familiar with the platform. Finally picked up a Gen 6 in the Harpoon Spanto and it absolutely lives up to the reputation.

Pros:
• Outstanding build quality and fit/finish
• Excellent ergonomics (the 3.5 handle just works)
• Rock-solid lockup and strong, confidence-inspiring detent
• Tri-Way pivot lets you tune the action exactly how you like it
• Harpoon Spanto blade is robust with a reinforced tip
• Factory edge was impressively sharp and cuts well given the blade thickness
• MagnaCut steel adds excellent toughness and corrosion resistance

Cons:
• Heavier than many modern EDC knives
• Premium price point

Overall, the Gen 6 keeps everything that made the XM-18 great and adds refinement. After carry

Excellent knife and excellent service from Knives Plus! 03/06/2026

I just received my Hinderer XM-18 3.5 and couldn’t be happier. Shipping was fast, communication was great, and the knife arrived exactly as described.

I had actually been searching for this configuration for a long time—the translucent G10 scale with the MagnaCut blade—and Knives Plus was the only place I could find it available.

This is my fourth XM-18 over the years, and it’s easily the best one I’ve owned. The action is smooth, the fit and finish are outstanding, and it immediately became my new EDC.

Knives Plus made the whole experience seamless from start to finish. Highly recommended!
