Hinderer XM-18 Gray - Working 3.5in Plain Working Harpoon Spanto XM1835HSWF

The Rick Hinderer XM-18 Gray & Working Finish Harpoon Spanto represents the evolution of a modern classic—refined, rugged, and purpose-built for those who expect more from their gear. Designed by Rick Hinderer, the XM-18 has long set the benchmark for hard-use folding knives, and this configuration delivers that legacy with updated steel and a bold, utilitarian aesthetic.

At the heart of this knife is a 3.5-inch Harpoon Spanto blade crafted from CPM S45VN stainless steel. This premium steel offers excellent edge retention, improved toughness, and outstanding corrosion resistance, making it an ideal choice for serious, real-world performance. The Harpoon Spanto grind combines the reinforced tip and slicing efficiency of a tanto-inspired profile with the flowing belly of a spear-style blade. The result is a versatile cutting tool that excels at everything from controlled detail work to heavy-duty slicing and piercing tasks.

Finished in Hinderer’s rugged working finish, both the blade and lockside are built to embrace honest use. The subdued, battle-ready appearance helps conceal wear while enhancing the knife’s tough, no-frills character. With a blade thickness of 0.16 inches, the XM-18 offers the strength and rigidity you’d expect from a Hinderer, giving you confidence when the task demands serious cutting power.

The integrated blade flipper ensures fast, decisive deployment. A quick press sends the blade smoothly into action, where it’s secured by a solid framelock. Lockup is strong and dependable, delivering the reassuring stability that defines the XM-18 platform. At 5.6 ounces, the knife feels substantial without becoming cumbersome, striking a balance between durability and carry comfort.

The 4.75-inch handle, paired with the 8.25-inch overall length, provides a full, ergonomic grip that supports extended use. The gray G-10 front scale offers excellent traction and durability while maintaining a clean, understated look. It’s textured for control and shaped to fit naturally in the hand, minimizing fatigue during demanding tasks. The titanium lockside, also finished in working finish, complements the blade perfectly, creating a cohesive, industrial aesthetic that’s both refined and rugged.

Every detail of the XM-18 reflects thoughtful engineering and real-world testing. From its robust construction to its precision machining, this knife is built to perform day in and day out. It’s not just a cutting tool—it’s a dependable companion designed to meet the demands of professionals and enthusiasts alike.
