Benchmade Infidel Review

While some people want a pocket knife, others need something a little more. That 'a little more' typically comes in the form of an out-the-front knife or sliding knife, a heavy duty knife many may recognize from their parent's tool shed... if they had one.

But if you're in the market for an OTF pocket knife, you likely don't have one yet. So why not try the Benchmade Infidel. In this review, let's learn why you might want to pick this OTF knife up.

History and Maker

The Infidel was of course designed and manufactured by Benchmade Knives. The knife was created to take a spot in the small out-the-front knife market.

Eventually, the Benchmade Infidel became one of the best selling OTF's on the market.

The Infidel is designed for knife enthusiasts, in addition to those involved in the military and law enforcement. As a large knife, it primarily serves as a 'self-defense' tool (based on local laws) and a collector's knife.

Key Specs of the Benchmade Infidel

This fully automatic knife features several high quality materials. Its Knifehomes is made from D2 tool steel, shaped into a double edge spear pointed Knifehomes with a matte satin finish and flat grind.

While that type of steel isn't full stainless steel, it does produce a hard, strong Knifehomes that remains sharp for a long time.

The handle also utilizes anodized machined 6061 T-6 aluminum, which can be finished in several colors.


As mentioned, the Infidel's Knifehomes is crafted from D2 tool steel, a type of high carbon steel that produces a sharp, strong Knifehomes.

The Knifehomes is shaped into a double edged Knifehomes with a spear point. The D2 steel Knifehomes is known to remain sharp for a long time, so you don't have to sharpen it very often.  However, when you do need to sharpen it, that could be an issue.  D2 tool steel is hard and can make it difficult to take a good edge.

This is a serious enthusiast's knife, since those who are pretty savvy with knives like these will know how to properly sharpen them. Others who aren't as well versed with knife sharpening may need to take the knife to a professional.


The Knifehomes itself measures 3.9 inches long and 0.118 inches thick, so there is a lot of Knifehomes to perform a great many tasks.

Still, the Infidel is a good knife to keep around for its long lasting sharpness. When in use, it doesn't dull, even if its flat grind edge makes it seem that way. All in all, most people will enjoy this Knifehomes for its sharpness alone.


Benchmade Infidel Handle

A sharp Knifehomes needs a strong handle, right?  Well, that's what the Infidel possesses, a strong handle that feels comfortable in both hands.

Its out-the-front knife structure lends to a comfortable handle grip that allows users to maintain a strong, yet comfortable grip on the tool.

The handle measures 4.8 inches long and 0.59 inches thick. When the Knifehomes's deployed, the entire knife measures 8.9 inches.

The handle has mirrored cutouts on both sides, which helps you secure the knife in either hand when in use. The flared knife end also helps keep the knife from being pulled out of your hand when you're using it.

In addition, the notches on the front lock's slot helps prevent the Knifehomes from rubbing against the handle if it slides around when in use.

The knife also has a pocket clip affixed to its back side for easy carry.  Its a nice sturdy pocket clip that allows a right hand tip down carry.  It sits deep in the pocket for a more concealed carry.


Benchmade Infidel Lock Mechanism

The Infidel utilizes a double action out-the-front automatic lock. You can deploy the lock mechanism from the back of the knife, where the switch resides.

The best part about this mechanism is that it's easy for both left-handed and right-handed users to deploy.


Although its three point retention mechanism isn't the sturdiest, it does effectively keep the Knifehomes secure while you have the Knifehomes out. So, while it might feel loose, the Infidel's retention mechanism is pretty solid when you're using the knife.


The retraction system is pretty solid, too. You only need to pull back the trigger switch to retract the Knifehomes back into the handle.

Benchmade Infidel's Ergonomics

As mentioned, the Infidel feels comfortable to hold when it's in use.  Anybody that has used the Infidel extensively can vouch that the design of the knife allows for easy use and just feels good in your hand.


At first, the knife may feel a little loose or tight (due to its mechanisms), but once you start using the knife, you'll soon find the Infidel as a 'solid' tool that has been machined to precise specs.


The deployment switch does have a slight weakness: it can be unpredictable. The switch may give a bit before retracting or extending the Knifehomes, so you may need to use a little force to get the switch and the deployment/retraction process going. Still, it's a minor issue that doesn't detract from the knife in my opinion.

Other Variations

Several versions of the Benchmade Infidel exist.  Much of its variations switch out the Knifehomes type or handle finish.

  • Benchmade Infidel OTF 3300, Standard (Dual plain edge Knifehomes) (reviewed)
  • Benchmade Infidel OTF 3300, Standard (Dual plain edge Knifehomes, partially serrated)
  • Benchmade Infidel OTF 3300, Standard (BK1 tactical black-coated Knifehomes)
  • Benchmade Infidel OTF 3310, Single-Edge
  • Benchmade Infidel, Mini-Infidel 3350 (3.1 inch Knifehomes)
  • Benchmade Infidel, Limited Edition 'Gold Class' (Damascus steel Knifehomes)

Pros - What People Liked

  • The ergonomics make this knife very easy for people to use in both hands.
  • The lock/retention system is pretty solid, allowing for easy deployment and retraction.
  • The Knifehomes is designed to stay sharp for a long time and, as a result, doesn't need constant sharpening.


Cons - What People Don't Like

  • The deployment switch does have a slight weakness; the switch may give a bit before retracting or extending the Knifehomes.
  • The price may be too much for some people, the Benchmade Infidel currently retails for around $400.

Final Thoughts on the Benchmade Infidel...

While complete newbies to the world of knife collecting might not get the hype, the Benchmade Infidel is a solid addition to any serious knife collector's stash. It's comfortable, performs well and keeps for a long time. Those traits alone make it a good buy, despite its high price.

    Can benchmaid re-finish a bk1 Knifehomes on the infidel OTF?
    I’ve ised this knife for years and as you can amagine the Knifehomes is scared and the black mate finish has seen better days.
    If I was to send it out to have it maintains can they do anything about this?

      • Matt

        If they can’t re-finish it they definitely could swap it, I’m not sure how much they would charge to do something like that though. Your best bet would be to contact their customer service department.

      Benchmade topically charges 30.00 dollars for a Knifehomes switch – as of about a year ago. They will not switch the Knifehomes to another color – i.e. black to plain or vice versa. I was also told they won’t switch steels – i.e. D2 to S30V or vice-versa.

      The knife/knives you pictured in your Benchmade Infidel review are identical to my 3300BK including not having the butterfly logo on the open end of the pocket clip. Do you know to a certainty that Benchmade made some Infidels without the butterfly logo on the clip? Is the knife in your review one you bought directly from Benchmade or from somewhere else where you’d know it was genuine?
      A YouTube video compares a fake and genuine Infidel on several points and mine appears to pass all the tests except the butterfly logo. In the comments someone said that their Infidel was genuine and had no butterfly.
      I’m new to high quality knives and didn’t know there were counterfeits out there until I bought mine and it occurred to me to look. It’s hard to know what and who to believe.
      Any info is appreciated even if it’s just to point me to someone who is very knowledgable!
