The Benchmade 3350BK Mini Infidel double action out the front automatic knife, designed by McHenry & Williams, is a favorite amongst law enforcement and military professionals around the globe and is praised for its rugged construction, solid durability and an "X" factor of pure awesomeness that one can only experience when owning one. The design of the black anodized 6061-T6 aircraft grade aluminum handle boasts a milled "step" design that transitions seamlessly into the design of the slide trigger. On the black dagger style blade, you will find a blood groove that runs the length of the blade on both sides that further enhances the already aggressive nature of this black class model. Furthermore, the enlarged slide trigger is housed on the broad side of the handle scale allowing for better accessibility, even while wearing gloves. This knife also comes with a MOLLE compatible nylon sheath and malice clip for multiple carry options. The deep carry pocket clip is designed for tip down carry only. Made in the USA.

Benchmade OTF Mini Infidel, Tactical, 3350BK
The Benchmade Mini Infidel was created for those who love the original Infidel but want a smaller knife. Built with a 3.1” tactical blade, the D2 Tool Steel double edge spear point blade is the perfect style blade for an OTF knife. The 6061 T6 aluminum handle is built for comfort and made so you can keep a solid grip on it. This is a top quality out the front knife sure to please.

The D2 Tool Steel blade on the Mini Infidel had a double edge spear point style. The blade boasts a 60-62 HRC and is 3.1” long. At .09” thick, the blade is the perfect size for everyday and not so everyday chores. D2 has fairly high chrome content at 12% but it isn’t quite high enough to classify it as a stainless steel. More stain resistant than carbon steels, D2 will outperform—in the strength department--most premium stainless steels. With high wear resistance and good toughness, D2 seems the perfect choice for the Mini Infidel. The blade sports a deep groove down the middle that gives it a great look.
The black 6061 T6 aluminum handle is comfortable and easy to hold. Built with the same “step” texturing as the original Infidel, the Mini fits nicely in the hand. The trigger is right where you want it. The handle has curves in all the right places. With a somewhat protruding area right at the top and a nice bump in the middle of the handle, the handle shape naturally puts your hand in the perfect spot for maximum control. The handle on this knife is going to be nearly indestructible and can stand up to extremely heavy abuse. At .54” thick, it is perfect for mid to large size hands.
The fire button stands proud right near the upper third of the top face on the handle. The trigger is the perfect “weight”. It isn’t too hard to slide up and fire the blade out, but it isn’t so stiff that the knife is frustrating to use. The trigger has the same “step” pattern as the handle. When triggered, the blade snaps out at a satisfyingly fast speed and locks into place about as tight as you can expect from a high quality OTF knife.

I think the Mini Infidel from Benchmade is one of the very best out the front knives on the market. Small enough to carry nearly anywhere, the knife is big enough to get the job done when it counts. It measures 7.1” open and 4” closed. And at just 3.4 ounces, you almost don’t even realize you have it on you. This is a serious out the front knife for those who demand the best. The knife has all the trimmings you expect from a Benchmade knife. From the deep carry pocket clip to the MOLLE compatible soft sheath, the Mini Infidel stands up and shouts quality. Get the Mini Infidel and let me know what you think. I can guarantee that you will love yours as much as I love mine.

    Great OTF for the price! The blade extension is very clean and efficient, as well as when it retracts. Nice sharp edges as well. I always wanted an Infidel, ever since The Gray Man mentioned one as his choice of knife, but the actual base Infidel model was larger than I wanted. Anyway, highly recommend!
