Among enthusiasts, Rick Hinderer Knives enjoys a reputation that blends art, engineering, and grit. Their folders are not simply pocket tools; they’re dependable companions built to endure punishment while looking like functional sculpture. The XM-18 3.5″ Skinny Harpoon Spanto – MagnaCut – Stonewash Blue/Black G10 embodies that philosophy perfectly, pairing premium materials with the unmistakable attitude of the Harpoon Spanto grind.
Below, we’ll walk through its design story, specifications, and real-world performance to see why this “Skinny” variant has become a must-own for anyone serious about hard-use knives.
A Knife with Attitude: The Harpoon Spanto Story
When you first set eyes on the XM-18 Harpoon Spanto, you notice its spine—muscular, ridged, and full of purpose. The grind takes the tried-and-true Spanto profile and strengthens it with a harpoon-style top line. That extra “meat” at the spine is more than just cosmetic; it reinforces the tip for heavy cutting, piercing, or scraping tasks.
The Skinny edition brings that same muscular blade into a slightly slimmer chassis. By trimming handle thickness without sacrificing structure, Hinderer has made a knife that carries comfortably yet feels robust in the hand. It’s a clever adaptation for those who love the standard XM-18 but prefer a lower-profile EDC.

Materials That Matter
CPM MagnaCut Blade Steel
MagnaCut is the latest super steel to earn its place in the spotlight, and Hinderer puts it to good use here. It blends wear resistance, toughness, and stainless qualities so you can take the XM-18 from humid summer hikes to winter workshops without fear of rust or chipping. For people who sharpen their own knives, MagnaCut is also pleasantly cooperative on stones and strops.
G10 Handle Scales
The handle is crafted from Blue/Black layered G10, machined to reveal subtle striping that adds both traction and visual intrigue. G10 is renowned for its strength-to-weight ratio, resisting impact, moisture, and temperature swings. The scales are supported by titanium liners and a stonewashed titanium lockside, forming a rigid frame for confident handling.
Stonewashed Finish
Hinderer’s signature stonewash treatment on both blade and lockside lends the knife a rugged, working-man appeal. Beyond aesthetics, this finish masks minor scuffs, making the XM-18 a tool you won’t be afraid to put to work.
Ergonomics: Comfort Meets Control
Rick Hinderer is celebrated for ergonomics, and the Skinny Harpoon Spanto is no exception. The handle contours allow a natural, secure grip whether you’re wearing gloves or working barehanded. A generous finger choil ahead of the flipper tab enables choking up for precise control during detailed cutting tasks.
Despite its reduced thickness (0.452″), the handle feels substantial without being clunky. The “Skinny” profile eliminates excess bulk, making the XM-18 easier to slip into a jeans pocket or clip to a waistband.
Deployment and Lockup
The XM-18’s flipper tab works in tandem with its phosphor bronze washers to provide a smooth, authoritative opening action. Once deployed, the blade locks solidly with Hinderer’s robust frame lock, featuring an overtravel stop for longevity.
The knife’s detent is tuned for reliability, allowing the blade to rocket open with a firm press while staying secure in the closed position. For users who appreciate mechanical precision, the XM-18 delivers satisfaction in every flick.
Performance in Use
Everyday Utility
From slicing cardboard to trimming rope or preparing camp meals, the Harpoon Spanto grind excels. The thick spine gives stability for prying or pushing cuts, while the razor-keen edge handles fine work with ease. The harpoon swedge adds strength at the tip, letting you tackle tougher materials without fear of snapping.
Outdoor Adventures
Whether you’re hiking, hunting, or setting up camp, the XM-18 is ready. Its MagnaCut blade shrugs off moisture and holds an edge even after carving tent stakes or prepping kindling.
Professional/Rescue Applications
Law enforcement, first responders, and tradespeople value the XM-18’s reliability. Its secure grip, stout lock, and responsive deployment make it an asset in demanding environments.
Style and Customization
Collectors love Hinderer’s attention to aesthetic detail. The layered Blue/Black G10 pops against the matte titanium lockside, giving the knife a two-tone look that’s striking without being flashy. As with other XM-18 models, you can swap scales, hardware, or pocket clips to make the knife uniquely yours.
Carry and Maintenance
Despite its solid build, the Skinny XM-18 rides discreetly in the pocket thanks to its trimmer handle. The reversible clip lets you choose tip-up or tip-down carry. Cleaning is straightforward: loosen the pivot, rinse, dry, and re-lubricate—the open-back construction keeps things simple.
