Benchmade Infidel 3.91in Automatic Folding Knives Review

Let’s Dive into Benchmade Infidel 3.91in Automatic Folding Knives

The Benchmade Infidel 3.91in Automatic Folding Knives is more than just a knife; it’s a statement. Manufactured by Benchmade, a company renowned for its commitment to quality and innovation, the Infidel is an out-the-front (OTF) automatic knife designed for tactical applications and everyday carry. Its rapid deployment, double-edged blade, and robust construction make it a standout choice for those who demand reliability and performance.

I was looking for a reliable, fast-deploying knife for personal defense and emergency situations. I wanted something that could be quickly accessed and deployed with one hand. The Benchmade Infidel’s OTF mechanism seemed like the perfect solution, offering speed and ease of use in a compact package.

Unboxing the Infidel was impressive. The knife feels substantial in hand, the black anodized aluminum handle exuding quality. The action is smooth and decisive, with the blade locking firmly into place. It’s clear that Benchmade paid close attention to the fit and finish.

I considered the Pro-Tech Dark Angel and the Microtech Ultratech before deciding on the Infidel. While the Dark Angel is known for its slim profile, I wanted something with a bit more heft. The Ultratech is also a strong contender, but I was ultimately drawn to the Infidel’s distinctive design and Benchmade’s reputation for excellent customer service.

My initial impression was excitement mixed with respect. The Infidel isn’t a toy; it’s a serious tool. Its rapid deployment and double-edged blade command attention, and I was eager to put it through its paces.

Real-World Testing: Putting Benchmade Infidel 3.91in Automatic Folding Knives to the Test

First Use Experience

I first tested the Benchmade Infidel at my local shooting range and on a weekend camping trip. At the range, I used it for opening ammo boxes, cutting rope, and general utility tasks. During the camping trip, I utilized it for food preparation, cutting kindling, and as a backup tool while hiking.

The Infidel performed admirably in both wet and dry conditions. The 6061-T6 aluminum handle provided a secure grip even when my hands were damp. The blade, made from D2 tool steel, retained its edge well after repeated use.

There was a slight learning curve with the OTF mechanism. It took a few practice runs to get the hang of smoothly deploying and retracting the blade. However, once I got the feel for it, the action became second nature.

The only minor issue I noticed after the first use was a small amount of blade play when the knife was fully extended. This didn’t affect the knife’s performance, but it was something I kept an eye on.

Extended Use & Reliability

After several months of regular use, the Benchmade Infidel has proven to be a reliable and durable tool. The black anodized finish on the handle shows minimal wear, and the blade remains sharp with occasional stropping. The automatic mechanism continues to function smoothly and reliably.

Despite frequent use, the Infidel shows no signs of significant wear and tear. The blade locks up securely, and the handle remains solid and comfortable in hand. The D2 steel has proven to be resistant to chipping and corrosion.

Cleaning the Infidel is relatively simple. I typically use a dry cloth to wipe down the blade and handle after each use. The integrated cleaning port makes it easy to remove any debris that may accumulate inside the handle.

Compared to other knives I’ve owned, the Benchmade Infidel stands out for its rapid deployment and robust construction. It outperforms many other automatic knives in terms of speed, reliability, and durability. The minimal blade play is still present, but hasn’t worsened with use.
