Benchmade Infidel Description
For quite a while rumors circulated about a possible Benchmade out-the-front knife, and finally this much-anticipated product arrived in form of the Infidel OTF. In addition to its incredibly stable, fast action and rugged, pure tactical nature, the knife boasts a cool factor that just has to be physically experienced to be described.
A marvel of knife engineering and one of the best OTF knives on the market, this quick-opening, sleek dagger which action or performance is as impressive as its looks features D2 tool steel in its blade construction. The Benchmade Infidel symmetrical, double-edged blade sports a grooved fuller on its centerline, and both edges are sharpened on the logo side of the narrow dagger blade only.
Another primary feature of this knife is its out-the-front (OTF) opening system that can be engaged in seconds using the ambidextrous thumb slide on the handle. This Infidel knife actuation switch or button mechanically and speedily fires the blade open – and closed when pulled back – without the user having to manipulate the blade directly. It is also located on the face of the handle, rather than on the side as is common with many other push-button knives.
The black anodized handle of the Infidel Benchmade dagger is of machined 6061-T6 aluminum construction; fits powerfully in hand; feels comfortable; and makes the dagger easy to use. This sturdy handle also has a milled “stepped” design which ensures that the knife will not be slipping out of your hand during use.
For easy transportation and concealed carry capability, the Benchmade Infidel is rounded out by a deep-carry, MALICE pocket clip made of steel. This tip-down, right handed carry clip is guaranteed to hold the knife securely to your pocket in any situation, and can also be removed if necessary.
Designed with purpose and built to last, the Infidel knife overall sets a high bar for durability and performance, and is ideal for self-defense, duty, or tactical applications, as a backup weapon or primary pocket knife.
A MOLLE® compatible soft Cordura sheath is included in the package, and this durable sheath serves as another means of carrying or storing the dagger conveniently and safely.

Benchmade Infidel Additional Information
Blade Material
The 60-62HRC D2 steel used to make the Infidel knife blade is a high-carbon, high-chromium tool steel that is stronger and more edge-retaining, but less tough and corrosion resistant, than steel alloys such as 154CM and 440C.
It may also interest you to know that knives with a D2 steel blade are a favorite of chefs, especially due to their strength and ability to hold an edge longer.
Blade Finish
The Benchmade Infidel 3300BK blade wears a black Cerakote finish. Cerakote is a specialized type of ceramic coating that enhances the resistance of steel surfaces against corrosion, chemicals, scratches, as well as general wear and tear, thereby increasing their durability.
Cerakote also makes steel surfaces look better; and the black color chosen for the Infidel Benchmade blade is especially suitable for tactical purposes as it prevents light reflection or glare, whether in the daytime or at night.
Handle Material
The machined 6061-T6 aluminum used to make the handle scales of this dagger is a lightweight yet exceptionally tough material. It is also naturally resistant to corrosion.
Handle Finish
To make the Infidel knife handle even much more resistant to corrosion, it has been anodized in black. Anodizing creates an oxide layer that is perfectly formed and scientifically controlled, resulting in excellent corrosion resistance and the preservation of the pure and natural metallic aspect of the material to which it is applied.
Anodizing also enhances the natural beauty of aluminum to some extent.
MOLLE Compatibility
A MOLLE compatible system such as the Benchmade Infidel sheath is one which uses modular attachment methods and is useable with US general issue MOLLE components. Bear in mind that “MOLLE” is an acronym for Modular Lightweight Load-carrying Equipment.
Construction Info
Every Benchmade blade is laser-cut from sheets of high-grade steel, ground, beveled, and finished with precision that is uncompromising; handles are milled and machined in-house to the most exacting specifications; and every knife, including of course the Infidel OTF, is hand-assembled and sharpened by highly trained technicians bringing to bear over thirty years of manufacturing excellence in the manufacturer’s state-of-the-art factory in Oregon City, Oregon.
Use & Maintenance
It’s important to keep your knife dry and lubricated because steel – regardless of grade and price – tends to eventually rust if subjected to unfavorable conditions. Should you notice any rust or spotting on your Benchmade Infidel blade, a semi-chrome metal polish is ideal for combating such.
Hand-wash your knife under warm water with dish soap only, and dry thoroughly. Note that dishwashers can cause serious damage to it that is not covered under the manufacturer’s warranty.
Just like other knives, this dagger is designed for use only as a cutting tool; and so it is not advisable to use the Infidel knife as a pry bar, chisel, screwdriver, etc., as such uses can cause serious damage.
Avoid grinding wheels and other high-powered machinery if you choose to sharpen your blade yourself (which may not be necessary as you’ll soon find out).
The handle, pivot, and pocket clip screws may have to be adjusted occasionally using T6 & T10 Torx drivers. The Benchmade Infidel manufacturer recommends applying a small dab of releasable thread-locker as needed.
Warranty
This OTF dagger is covered by an extensive warranty as Benchmade, who always stand by their products, is committed to building the highest-quality knives through world-class craftsmanship, constant innovation, and unsurpassed materials.
LifeSharp Services
The Infidel Benchmade is also covered by the manufacturer’s LifeSharp service which guarantees that Benchmade will re-sharpen your knife to a factory edge for free, for the lifetime of the knife. These LifeSharp services include cleaning, oiling, adjustments, and re-sharpening.

Infidel Knife Reviews
Users all around the world have good things to say about what is arguably the best OTF knife. The following are some reviews of the Benchmade Infidel, drawn from various sources to give you a good idea of how the dagger is perceived:
![](https://armsintel.com/wp-content/uploads/2024/02/bmi-rev.png)
“The Infidel has been fighting quality control issues since its issue. This 2022 release has finally arrived in dashing fashion. Gone are the wiggles and blade play after opening. They are so confident they are releasing spare blades to be installed by shade tree technicians. There’s even a new 3.1” release in M 390 with spare blades at $59.95 a pop. Nothings new but QC is finally over the top American made OTF that can compete with MicroTech. Don’t neglect this as a new model because it surely is. Owning this and countless Micro Techs and three older models of the Infidel I’m at last proud to own a Benchmade Infidel.”

“So well made. Typical BenchMade quality. Very smooth. ZERO blade play. No wobble. I own a lot of OTF knifes. And this has got to be my number one. Next up would be my collection of Guardian Tactical OTFs. But that’s another review. By the way. This BenchMade was bought from BHQ. Buy this OTF. You won’t regret it. I hope this helps. Jef C.”

“I’ve wanted an Infidel for years, the price was always a little prohibitive. I finally got over it and I’m glad I did. Solid knife, smooth action, razor sharp out of the box.”
![](https://armsintel.com/wp-content/uploads/2024/02/bmi-rev4.png)
“I have several OTF-type automatics and this one definitely takes the cake.
It arrived perfectly and carefully packed in an original box and inside a holster. It was mercifully free of any blemishes or oil on the blade and handle.
The action is solid, satisfying and pretty unbelievable considering the size of the blade. It’s well-constructed, feels good in the hand and even has a feel of balance that I haven’t had before with OTF knives. The handle is textured and definitely customized for this particular model. I particularly love the ridges under the release that allow for a better grip.
I have nothing negative to say about this knife. It’s amazing.”

Benchmade Infidel Variants
The Infidel knife has several variants based on handle and blade finishes, blade material, as well as blade and overall length. Our focus model (3300BK) with black blade and handle is the Infidel Black, and its direct variant is the Infidel Black w/ Satin Blade (3300):
![Benchmade Infidel w/ Satin Blade](https://armsintel.com/wp-content/uploads/2024/02/3300-300x300.jpg)
Both are identical in all respects except for the differently-colored blades.

Infidel Crater Blue (3300-2301)

Infidel Woodland Green (3300-2302)

Benchmade Mini Infidel
For users who’d prefer a smaller sized knife, the manufacturer of these best OTF knives also offers the Mini Benchmade Infidel.
Made using the same superior materials – 60-62HRC D2 tool steel, black anodized, machined 6061 T-6 aluminum – and featuring the same components – ambidextrous thumb slide opener, deep-carry pocket clip, etc. – as their full-size counterparts, the Benchmade Infidel Mini models are more compact with a blade measuring 3.1 inches and an overall length of 7.1 inches.

If you’re on a budget, another OTF knife to consider is the CobraTec CTK 1. This one is also offered in various blade shapes, including dagger or spear point, but the knife’s blade activation/deactivation button is by the side of its handle instead of the face or front as is the case with the Benchmade Infidel.
