Benchmade 375FE-1 Shane Sibert Adamas Fixed Blade Knife 4.2″ CruWear Flat Dark Earth Plain Blade and Skeletonized Handle, Desert Tan Injection Molded Sheath

The Benchmade 375FE-1 Shane Sibert Adamas fixed blade knife exists because the last thing your loadout needs is another heavy piece of gear to weigh you down. Re-engineered to be stronger than ever before, it carries a 4.2 inch CruWear blade in a Flat Dark Earth plain grind, a skeletonized handle, and a desert tan injection molded sheath. Machined from CPM-CruWear, the blade brings upgraded corrosion resistance and toughness front and center.

A fixed blade has no pivot, no lock, and no failure point in the middle of the tool. That is the whole reason serious users keep one on the belt, and it is the reason this design has stayed in the lineup through multiple generations.

What the Benchmade 375FE-1 Shane Sibert Adamas Is Made For

This is a hard-use field knife, sized for real work rather than for a display case. At 4.2 inches, the blade is long enough to break down game, split kindling with a baton, cut webbing and cordage, and handle utility tasks that would flex or fold a lighter knife. The skeletonized handle removes material where strength is not needed, which is how the weight comes down without the strength going with it.

Service members, first responders, guides, and backcountry hunters are the natural owners here. So is anyone who has ever had a folder fail at the worst possible moment and decided never to repeat the experience. Modify with the times, and carry with confidence.

Key Features

• 4.2 inch blade machined from CPM-CruWear for upgraded corrosion resistance and toughness
• Flat Dark Earth plain edge finish that resists glare and hides wear
• Skeletonized handle that cuts weight without sacrificing rigidity

Steel, Sheath, and Specifications

CPM-CruWear is a powder metallurgy tool steel, and the powder process is what gives it a fine, uniform grain structure. In practice that means better toughness at a given hardness, so the edge resists rolling and chipping under lateral load. The upgraded corrosion resistance is a meaningful improvement for a tool steel, though it is not stainless and still wants a wipe-down and a light oil film.

The sheath deserves as much attention as the blade. Injection molded in desert tan, it was redesigned specifically to mount with low profile MALICE CLIPS, which means the Benchmade 375FE-1 Shane Sibert Adamas can ride flat on MOLLE webbing on a plate carrier or pack, or hang from a standard duty belt without a bulky adapter. That flexibility is what lets one knife serve across kit configurations.

Carry, Care, and Compatibility

Mount the sheath where your dominant hand can reach it without breaking your grip on anything else. On a belt, that usually means strong side behind the hip or on the support side for a cross draw. On a plate carrier, the cummerbund and the front panel are the two positions most users settle on after some experimenting.

Dry the blade after use and wipe it with a light oil before storage, particularly if it has seen salt water, blood, or acidic plant matter. Rinse the sheath out rather than letting grit build up inside, since sand trapped in a molded sheath will scratch a blade every time you draw it. Check the clip hardware periodically the same way you would check any load-bearing attachment.

Sharpening is straightforward because the grind is a plain edge with no serrations to work around. A coarse stone to set the bevel, a fine stone to refine it, and a strop to finish will keep the Benchmade 375FE-1 Shane Sibert Adamas shaving sharp indefinitely. Learn to maintain it yourself rather than sending it out, since a field knife is only useful when it is sharp on the day you need it.

Fill out your kit with lights, packs, and field gear from our apparel and gear collection and you will have a loadout that works as a system instead of a pile of parts. The toughest just got tougher, and lighter. Ships direct to your door, no FFL required.
