Benchmade Infidel Knife OTF Double Action Automatic (3.9" Satin) 3300

We have many other Benchmade Infidel Knives in stock!

Rumors circulated for years about a possible Benchmade OTF knife. Good news Benchmade lovers- the knife has arrived. The Benchmade Infidel 3300 is, to put it mildly, awesome. D2 tool steel double edged blade. Anodized T6 aluminum handle. And a pocket clip for easy carry.

Blade HQ's Benchmade Infidel Review is, to put it bluntly, about time! A few features we really like is the sliding button on the face of the handle, instead of the side as many others have. The milled "stepped" handle design assures that this knife will not be slipping out of your hand.

I have wanted one of these for years. I finally got my hands on one about a month ago and it is everything I had hoped it would be. Wicked sharp out of the box. Sturdy build quality. The material on the handle feels great. The action is just about perfect. I fidget with this thing almost daily and it’s very satisfying. If you have been on the fence about picking up an Infidel, don’t be like me and pick one up. It is worth it. I have had a Microtech OTF as well and prefer this design much more.

My 1st OTF!
Jon R. on Jan 6, 2020

I was very pleased with this OTF when I got it out of the box. Very well made and SOLID! Looks and feels great in the hand as well. Just started buying a few knives and the video helped with the decision. Purchased 2 other styles of knives from BladeHQ and Iove them as well. Thanks!

Sweet piece
Lucas K. on Aug 3, 2019

Definitely not an EDC. But one of my favorite talking pieces. Well constructed fun to use and my friends love it. It’s sure to start a conversation.

Joshua M. on Aug 27, 2018

Absolutely astonishing knife. One question. I recently dropped it in some water on accident and every time I open it I see small droplets of water come it of the knife. Will this affect the knife in the long run?

Looks, fires, feels great!
Shawn J. on Jul 12, 2018

Solid strong firing really nice knife. So all this sh*t about blade play I've read online is so negligible its not worthy of mentioning. It's a solid knife. I also fired it into my leg to prove to gf how easily they kick out. Ahahahah yea wont be doing that again. It went in somewhere between. .25- .5 inch. Lol Seems to fire pretty hard to me. Razor sharp too! Its quality no doubt! Another fine purchase from Bladehq (ordered sunday night. got it 4 days later Thursday at 3pm). I gotta stop looking at bladehq to get to sleep... gotta stop ordering knives for a minute..

Better Than Anticipated
RJ H. on Jan 7, 2018

The Infidel has been a grail knife for me since its release a decade ago, and I wish I had caved on it sooner. This knife is so much better than I thought it would be, which is saying a lot. The edge was razor sharp out of the box, and I've had no malfunctions after a few thousand fires and a year in EDC rotation. You do have to maintain it though; OTFs are inherently fiddly and finicky. That said, I can't recommend this knife enough, even with the price considered.

Dangerous sheik!
Richard D. on Jan 6, 2018

Had for over 10 years now. Has held up great although not an edc for me due to legal constraints. Just had to have it and can because I live in the good old USA. Very sexy knife. I know as it makes the wives feel coquettish.

Steve S. on Jun 13, 2017

Ive owned an Infidel for almost a year. It is a never-fail piece of quick, sharp equipment. You get your money's worth with this knife. Recommend.

An Excellent OTF!
Donald M. on Apr 22, 2015

No double about it, the Benchmade Infidel OTF auto is an expensive knife. But, as the old saying goes, "you get what you pay for." I have been carrying an Infidel for over a year now and it has never, not even once, failed to properly extend or extract the blade. As a rule I "test" it each day before carrying, sometimes several times (just for fun). I can honestly say that I have, in the past year, done this over 1000 times and, as stated, it has worked flawlessly each and every time. Pricey? Yes! Worth it? Definitely! Update (August 2016): Over two year of carry now and still no malfunctions. Still works perfectly every time.

Curtis H. on Jun 17, 2022

First of several Benchmade knives I've owned that came with a dull blade. Typically slick Benchmade quality and action, but the sharpness factor is pretty disappointing for a $400 piece of steel.

Respectable large blade OTF
Zach W. on Mar 8, 2016

The fit and finish of this blade is very good. It fires and retracts every time. The blades thin profile is probably only for defensive purposes. It feels less solid than other OTFs though.

Good for what it is
Daniel J. on Feb 23, 2019

OTF knives are a mixed bag. They're cool, but not practical. Dagger-grind blades, same deal. This is a better-than-average OTF. The action is smooth enough, the lockup is strong enough. A compromise, but a sensible compromise. It isn't a Sandshark, but those things were a pain to open. Build quality is good. This isn't a Hawk Deadlock, but it compares fairly well with Microtech OTFs. The strangest thing about this knife is the choice of steel. D2 is an odd choice for a knife you can't clean. If you really need this knife to be what it is, it should stand up well when you need it. But if you don't need the push-button release, a conventional folder is much stronger.

Love BM but...
Maxwell M. on Nov 5, 2018

Worked at a knife store for a good chunk of time, played with countless infidels and they all seemed to have the same three problems: Lots of blade play, d2 steel. and cost. Production knife in d2 and alumninum is not worth 400$. Also I don't like the blade shape, just don't find it that useful...

Not Worth the Money
Mario A. on Nov 14, 2022

I was thinking of buying one until I handled a coworker’s infidel he just bought. The main issue to me was the amount of blade play and the cheap choice of steel for the price. I feel like you should be able to get better quality materials and craftsmanship. I’d advise to look into different brands.

Just don't bother
Tristan B. on Mar 7, 2021

I've handled several infidels and microtechs, heretics, and guardian tacical OTF's. Benchmade makes by far, the most overpriced ones on the market. Sure it's not hot garbage, but for $400 it is. This should be around $100 realistically. Buy a microtech, it's better in every single way and will actually last, at a better price too.

Pure garbage
Matt M. on Aug 7, 2018

Awful material. Terrible design. I could take my sink apart and make a better knife out of it.
