Benchmade 431SBK-1 Redoubt Folding Knife

Benchmade 431SBK-1 Redoubt folding knife from the Black Class series

It will be perfect for use as an EDC or tactical knife. The knife has a typically working purpose, so the blade is made of hard D2 tool steel, which has high retention and impressive wear resistance.

The Benchmade 431SBK-1 Redoubt is a folding knife that bridges the gap between an EDC knife and a typical tactical knife. The knife has a minimalist design, a size perfectly suited for everyday carry, and excellent cutting qualities.

The Benchmade 431SBK-1 Redoubt folder has a partially serrated blade, allowing efficient cutting of fibrous materials, belts and ropes. The serrations are applied close to the handle, so we can simultaneously work with a smooth and serrated cutting edge.

Features of the Benchmade 431SBK-1 folding knife:

• Tool steel D2: The head is made of high quality CPM-D2 tool steel, hardened to 60-62 HRC.
• Tanto profile: 90 mm long blade with Tanto profile, finished with Cerakote® coating to protect against corrosion and give the knife a military feel.
• Serrated blade: The knife features a combo blade with a partially serrated cutting edge. Perfect for cutting ropes, belts and fibrous materials.
• Axis Lock Mechanism: The double-sided Axis Lock provides security for use and is valued for its durability and resistance to dirt. The mechanism is easy to use for both right- and left-handed people.
• Grivory plastic facings: the handle is made of Grivory, a glass-epoxy laminate that features light weight, high mechanical strength and resistance to chemicals and sudden temperature changes.
• Convenient unfolding: the blade can be instantly unfolded with one hand, thanks to a double-sided peg, and phosphor bronze pads ensure smooth movement.
• Ergonomic and Secure Grip: The aggressive texture of the facings provides a secure grip while working, increasing safety and control of the tool.
• Lanyard hole: The hole in the back of the handle allows you to attach a lanyard or decorative paracord braid.
• Discreet carrying: The high-set clip allows you to conveniently carry the knife in your pocket.

Benchmade 431SBK-1 Redoubt - D2 steel EDC knife

The blade is made of excellent CPM- D2 steel hardened to 60-62 HRC. CPM-D2 is a powdered variant of air-hardened D2 steel, but with much better retention and a modified carbide microstructure that makes the blade outstandingly resistant to wear, impressively long-lasting sharpness and relatively easy to sharpen.

With such parameters, CPM- D2 is a great alternative to much more expensive super steels, especially if you do not have a sizable budget. However, it is worth remembering the proper maintenance of the knife, so that the knife will serve reliably for years to come. When choosing a knife made of such steel, it is worth getting a diamond sharpener, as sharpening with a standard ceramic whetstone can be very labor-intensive and inefficient.

Tanto profile 90mm long blade with Cerakote® finish, which protects the steel from corrosion and gives the knife a military feel. The head can be instantly unfolded with one hand, using a double-sided peg. Thanks to the use of phosphor bronze washers, the blade runs smoothly and dynamically.

Benchmade's flagship mechanism, the double-sided Axis Lock, valued for its tremendous mechanical strength, dirt resistance, and ease of use for right- and left-handed users, is responsible for safe operation.

Benchmade 431SBK-1 Redoubt has molded Grivory plastic facings in green color. Grivory is a glass-epoxy laminate that is characterized by light weight, high mechanical strength, resistance to many acids and solvents and sudden temperature changes. Thanks to the aggressively textured overlay, we get an extremely secure and safe grip on the knife while working.

A hole in the back of the grip allows you to attach a lanyard or decorative paracord braid. To increase the reliability and strength of the design, the knife uses skeletonized steel reinforcing inserts (liners). Carrying the knife discreetly in your pocket is made possible by the high-set clip (non-transferable).
