Benchmade 581BK-04 Osborne folding knife

The Benchmade 581BK-04 Barrage is a versatile everyday carry folding knife that combines premium materials, advanced safety features, and ergonomic design for reliable performance in any situation. This model features a robust CPM-S30V stainless steel blade, a contoured handle with Richlite laminate liners, and Benchmade’s renowned Axis Lock system.

Blade and Steel
The blade is crafted from American CPM-S30V stainless steel, known for its excellent edge retention, high mechanical strength, and strong corrosion resistance. With a hardness of 58-60 HRC, this steel maintains sharpness over time and is well-suited for demanding tasks. The blade has a drop point profile with a satin finish, offering a balance of durability and cutting efficiency. The flat grind and gently curved cutting edge ensure smooth, precise cuts, while transverse jimping on the spine provides extra finger support for detailed work. The blade is 91 mm long and 3 mm thick, striking a balance between strength and functionality.

Coating
The blade is finished with a Cobalt Cerakote ceramic coating, which provides outstanding protection against abrasion, corrosion, and harsh conditions without compromising sharpness or cutting performance.

Opening and Locking Mechanism
The assisted opening mechanism, powered by an internal spring, allows the blade to be deployed quickly and easily with a gentle push on the double-sided thumb stud. This makes one-handed operation convenient for both right- and left-handed users. The knife features Benchmade’s Axis Lock system, valued for its strength, dirt resistance, and ambidextrous use. An additional safety lock prevents accidental opening or closing, with the safety slide positioned on the back of the handle.

Handle and Construction
The handle features Richlite laminate scales, which are durable, environmentally friendly, and provide a secure grip. The contoured shape, finger cutouts, and slanted grooves enhance comfort and control during use. The handle is reinforced with sturdy 420 steel liners for added strength.

Carry and Use
A reversible pocket clip allows for discreet and convenient carry on either side of the handle, making it easy to adapt to your preferred carry style.
