Perfection
Doug R. on Jun 5, 2021

Knife is beautiful in every aspect. Love the blue handle. Super smooth action, razor sharp. Cool factor is off the chart.

There Can Be Only One!
Randy S. on Aug 2, 2021

In a world filled with Microtech design internals, the Benchmade Infidel stand above! While others rely on Aluminum or Zinc alloy chassis to support the blade, the Infidel uses a sandwich of polished steel to create a superior, low-friction blade path! The steel inserts also help support the dual, stainless steel blade locks which ride on massive pivots! The Aluminum handle halves provide rigid support for the steel sandwich, making use of the best materials where they are needed! the twin blade locks ensure the blade cannot fail...the only way to break a blade lock is to destroy the knife! The Infidel also uses compression coil springs which insure long-term reliability versus extension coils prone to fail where the single coil is connected to the hook. The Infidel uses a massive center rod to guide the drive springs, with even more massive drums on either end to actuate blade action. Everything inside an Infidel speaks to benchmade's commitment to build a knife that can stand up to anything and last nearly forever under constant use. I've seen an Infidel stabbed into a heavy wooden panel, then TWISTED and shoved through...the blade held as did the blade locks! The double-edge blade will pierce body armor like it's not there, which could mean the difference between going home, or going to meet Jesus! There is only ONE knife designed and built like the Infidel...it's called, THE INFIDEL! One Week Update! So initially my Infidel had no blade movement. After about a week and maybe 50 opening cycles I noticed the blade suddenly had a lot of play! It would literally flop side to side across the blade faces, and even rock side-to-side along the edge line! so I decided to take a peek inside, and instantly saw the problem. There is a locking boss that fits through the blade shank and is retained in place by a single machine screw. This screw had backed out and was allowing the blade to move independently of the locking boss, even as the boss was held fully immobile by the twin blade locks! So I lifted out the blade and tightened the screw and sure enough all blade play was gone, though after just a few cycles I could once again feel the blade rock along it's edge axis, and within just a few more cycles the blade was flopping once again! So this time I applied Red Loc-Tite and now the blade is completely locked with ZERO blade movement! I guess we shall see how well the thread locker works. One of the design aspects of the Infidel is that the locking boss has a flat front and slightly curved back. When the blade is fully forward, the boss is held hard against the front of the lower steel boss guide, and the twin blade locks swing in behind the boss on either side with their arc corresponding to the angled rear section of the locking boss. The result is a solid, 3-point lock-up that holds the boss with zero movement allowed. When the boss is adequately secured to the blade shank, the blade too exhibits zero movement in any axis. So any play, or movement of the blade means the screw has loosened. The first thing noticed is play along the edge axis, followed by play along the face axis as the screw backs itself out. Benchmade put thread locker on the external screws but none on that most critical screw, though one would have expected it. SECOND UPDATE after several weeks: After using Red Loc-tite on the screw that anchors the locking boss to the blade shank, the blade is now rock solid even after several weeks of constant carry and frequent blade deployment. Also, the open action has now smoothed out to a gentle, low-resistance push with rapid blade firing and lockup. The more I handle this knife the more I prefer it!

The best otf I’ve seen
ALEXANDER W. on Dec 17, 2021

This knife is simply gorgeous to look at and even more beautiful when you feel it in your hand. Most people say blade play is a given with otf knives but this one has zero unless you’re really trying to get it to move but you could say that about almost any knife. The blue color looks phenomenal, the jimping is just right doesn’t destroy pockets but when you’re holding the knife it’s not going anywhere unless you want it to. All around a must buy and thank god I did because looks like this coloration is discontinued now which I really wish benchmade would stop doing, but what can you do?

Substantial & Flawless!
John H. on Oct 5, 2020

When I first unboxed this Benchmade I was surprised by the heft and solid feel of this OTF. It's perfect in every respect!

Another beautiful Benchmade
Scott G. on Aug 24, 2020

It's a gorgeous knife, very sharp out of the box. Handle fits the hand nicely though it's not as grippy as the olive green version which has coarser anodizing. The action is very smooth with just a little blade play. I sure wish it was legal to carry here.

Quality Control
Chris M. on Jun 24, 2021

Blade HQ has excellent customer service and policies. There is no issue with their services at all as a reseller/distributor. The knife is dull. There were chips on the coating. The coating on the knife blade covered parts of the knife edge indicating it was not properly sharpened. One side will cut paper, the other side will not. As a reasonable person, I expect any knife “out of the box” to be razor sharp. Supported by similar reports from various forums in recent years it appears benchmade has some cases where items received are dull. I could not say how prevalent this is, however of the two infidels ordered, both were dull. That said, I have seen their knives in store which have a more typical blade shape for cutting/slicing which were sharp and could shave hair. So it could be by design that this is simply a piercing or stabbing oriented blade shape which accounts for the issue or just a random incident of QC. However, I have multiple spear/dagger shaped blades which came extremely sharp compared to this from other manufacturers. The mechanical function otherwise seems to be flawless. Since it is given that the primary function of a knife is to perform cutting tasks I have ranked this subjectively lower. Only an opinion of this one knife. Otherwise there other knives I have used have been well made with better than average support services and policies.

Overpriced!!
Roderick S. on Feb 7, 2022

This knife has a weak spring, excessive blade play and Benchmade has poor customer service. I will not waste anymore of my money on Benchmade knives
