For those privileged to carry a tactical automatic knife, the Benchmade Infidel 3310 offers the same intimidating features as the earlier Infidel 3300, but with a single edged blade that’s easier to use in ordinary work.
Owners will still be most impressed by the tactical advantages of this Out-The-Front automatic knife. Double-action blade deployment allows blade extension and blade retraction by simply pushing a slide button forward or backward. In any situation where one-handed use is essential, the Infidel series gets high scores. The handle scale beneath the pocket clip has a smooth surface for less friction when withdrawing the knife, and the over-sized stepped slide button simply can’t be missed. In a situation where you can’t afford to fumble for the button, you’ll know where this one is.
The opposite scale of the anodized T-6 aluminum grip shows a textured surface for better knife retention. The large size of the handle, 5 inches when closed, allows part of the grip to protrude beyond the palm for striking. The S30V stainless steel blade holds an edge well, hardened to 58 to 60 on the Rockwell scale. Benchmade calls the styling of the 3.95-inch blade a utility drop-point. The silhouette of the blade shows a straighter spine with enough width for safe back pressure during heavy cutting work..
Only active duty military, law enforcement personnel, and other special-use categories can legally carry automatic knives. If you’re a civilian interested in an OTF design, try the Smith & Wesson Assisted Opening OTF knife.
