The Benchmade 3400BK-2 Autocrat Auto out the front knife carries a 3.71 inch black DLC coated S30V double edge dagger blade in a coyote brown G10 handle. It continues the precedent for speed and style set by the original 3400 Autocrat and sits at the sharp end of the out the front platform.
An OTF knife deploys straight forward from the front of the handle rather than pivoting open. It is fast, it is one handed, and it works the same whether your palm is up, down, or somewhere awkward in between.
What Makes the Benchmade 3400BK-2 Autocrat Auto Stand Out
Designed with both everyday carry and tactical enthusiasts in mind, this quick and lightweight G10 handle OTF performs just as well as it looks. That combination of light weight and serious hardware is exactly what makes the Autocrat family so well regarded.
The double edge dagger blade is a specific choice. A dagger profile is symmetrical, sharpened on both sides, and optimized for penetration rather than for slicing rope or breaking down boxes.
That makes this a defensive and tactical tool first. If you want a general purpose utility knife, a plain edge drop point serves better. If you want a fast deploying dagger with premium steel, this is the category leader.
Key Features
The specifications that define this knife in hand:
- 3.71 inch double edge dagger blade in premium CPM S30V stainless steel
- Black DLC coating for corrosion resistance and a low reflectivity finish
- Out the front automatic deployment for fast one handed opening and closing
- Lightweight G10 handle in coyote brown for grip and durability
- Part of the Autocrat line from Benchmade, built on the original 3400 platform
Steel, Coating, and Handle Details
S30V is a powder metallurgy stainless steel developed specifically for knife blades. It balances edge retention, toughness, and corrosion resistance better than most alternatives, which is why it has become a benchmark for premium production knives.
The black DLC coating adds a hard, low friction surface layer over that steel. It reduces glare, resists rust, and holds up to contact far better than a simple painted or oxide finish.
G10 is a fiberglass laminate that stays dimensionally stable in heat, cold, and moisture. The coyote brown colorway pairs naturally with modern gear and hides field wear far better than a glossy handle material would.
Weight is the quiet advantage of the Benchmade 3400BK-2 Autocrat Auto. Many OTF knives feel like a brick in the pocket because of heavy metal handle scales, and a G10 bodied design carries all day without dragging a pocket down.
The 3.71 inch blade length lands in a useful middle ground. It is long enough to be a serious tool, but not so long that the closed handle becomes unwieldy in a front pocket or on a belt clip.
Carry, Maintenance, and Legal Notes
An OTF action needs to stay clean to stay fast. Pocket lint and grit are the enemy. Blow the channel out with compressed air periodically and add a drop of light lubricant to the track rather than flooding the mechanism.
Sharpening a double edge dagger takes patience. Work both edges evenly, maintain the original angle, and use a guided system if you are not confident freehand, since an uneven grind on a symmetrical blade shows immediately.
Automatic knife ownership and carry rules vary widely by state and city, so confirm what applies where you live before you carry one. Store the knife dry, wipe the coating down after handling, and browse the rest of our apparel and gear collection for sheaths, lights, and everyday carry support items.
Fast, light, and built from serious materials, the Benchmade 3400BK-2 Autocrat Auto is a knife that earns its keep through sheer quality of execution. Ships direct to your door, no FFL required.
