Benchmade 3400BK Autocrat AUTO OTF Knife 3.71″ Black S30V Double Edge Dagger Blade, Black G10 Handles

The Benchmade 3400BK Autocrat AUTO OTF knife is defined by speed and style, and it represents the latest out the front technology for tactical users and everyday carry enthusiasts alike. The 3.71 inch double edge dagger blade is CPM-S30V steel with a black finish, riding in black G10 handles. This is Benchmade’s first out the front design to use composite handles, blending the durability and wear resistance of G10 with a flash of colorful hardware and components. The result is a completely different feel in the hand.

What the Benchmade 3400BK Autocrat AUTO Knife Is

An out the front automatic deploys the blade straight forward from the front of the handle rather than pivoting it out from the side. That mechanism gives you a knife that opens and closes with a single thumb slider, in line with the handle, which is why the format is so popular with people who work with gloves or with one hand occupied.

The 3400 Autocrat carries the classic double edge dagger profile borrowed from the Infidel that inspired it. That blade shape covers a wide variety of applications and remains one of the most recognizable silhouettes in the automatic knife world.

Specifications and What They Mean in Hand

CPM-S30V is a powdered stainless steel that has become a benchmark for premium production knives. It holds an edge well, resists corrosion, and sharpens back to keen without specialized equipment. On a double edge dagger it means two working edges that stay usable through real work.

G10 is a fiberglass laminate that is dimensionally stable, impervious to moisture, and far more wear resistant than most polymers. Swapping to composite handles is what makes this knife so light, and weight is the single biggest factor in whether a knife gets carried every day or left at home.

The 3.71 inch blade length puts the Autocrat in the full size tactical category while keeping the closed length manageable in a pocket. Round out your everyday carry with more knives, lights, and tools from our apparel and gear collection.

Practical Use, Care, and Legal Notes

Keep the slider track clean. Out the front automatics rely on a spring driven carriage moving inside the handle, and pocket lint is the most common cause of sluggish deployment. A blast of compressed air and a drop of light oil on the rails restores snappy action in seconds.

Dry the blade after wet use even though S30V is stainless. Stainless resists corrosion, it does not ignore it, and a dagger grind has two edges and a fine point that will show pitting first. Wipe it down and store the knife dry.

Sharpening a double edge dagger takes patience because you are maintaining two edges that meet at a narrow point. Work each side with light, consistent strokes and match the factory angle rather than reprofiling. A ceramic rod or a fine stone will keep it in shape between full sharpenings.

Automatic knife laws vary by state and city, so confirm what applies where you live and where you travel before you carry the Benchmade 3400BK Autocrat AUTO knife on your person.

Fast, light, and built from serious materials, the Benchmade 3400BK Autocrat AUTO OTF knife earns a spot in the pocket of anyone who appreciates precision mechanics. It is a knife that gets carried, not admired from a shelf. Ships direct to your door, no FFL required.
