VF-1 Double Action OTF Knife – 3.25" 440C Stainless Steel Automatic Knife
$99.95
Blade Style:Double Edge
size:Large

 



The VF-1 Double Action OTF Knife is a compact, full-featured out-the-front automatic knife featuring a 3.25-inch 440C stainless steel blade, double-action deployment, textured zinc alloy handle, and reversible pocket clip. Its 7.75-inch overall length provides a balanced size for customers looking for an everyday carry OTF knife without stepping up to an oversized design.

The double action OTF mechanism allows the blade to deploy and retract using the same ambidextrous sliding button. Push forward to automatically deploy the blade out the front of the handle, then pull the button backward to retract it. This makes the VF-1 quick and straightforward to operate from either hand.

Its 3.25-inch 440C stainless steel blade features a partially serrated edge that combines a plain cutting section with aggressive serrations for a versatile all-purpose blade configuration. The blade profile is designed to handle both slicing and piercing tasks.

The textured zinc alloy handle provides additional grip while maintaining a solid feel in hand. A reversible metal pocket clip allows the VF-1 to be configured for button-forward or button-back carry while maintaining a low-profile position in the pocket.

For additional utility, the VF-1 includes an integrated glass breaker pommel at the end of the handle. At 7.75 inches overall and 6 ounces, the VF-1 combines a compact OTF profile with a substantial 3.25-inch blade.

Whether you're looking for a double action OTF knife, automatic out-the-front knife, partially serrated OTF, or compact 440C automatic knife, the VF-1 delivers the core features of an OTF platform in an everyday-carry-friendly size.

Customer photo review of 40% OFF VF-1 Black D/A OTF (Multiple Blade Styles Available)

Mannn... So far, this $49.95 monthly subscription is on 🔥 🔥 🔥!!!!! This is my third monthly installment and they just keep getting better and better. I mean I was pretty good at 'rithmetics in school and, assuming my maths are mathing correctly, I've paid in roughly $149.85 and have received roughly $308 worth of merch!!!! Look, if you're kinda interested or considering joining this subscription... WHAT IS STOPPING YOU??? This has GOT to be THE best knife club or subscription you can get in. This all started when I went on BladeCity and ordered the VT Apollo OTF and got a free random knife for ordering more than $79. I was informed by Dan, of BladeCity, that VT had this subscription and that all VT knives have lifetime warranty. I LOVE lifetime warranties. I figured, "Ehhh... What the hell? Why not?" I first got the 440c Blue Ghost Tanto. Next, the D2 Black Ghost DE. Now, this 440c VF-1 DE!!! You absolutely CANNOT lose with this subscription!!!! Stop wasting time and get in it!!!

Customer video review of 50% OFF Black VF-1 D/A OTF (Multiple Blade Styles Available)

Love the quality/price ratio of VT knives. I like the feel and action of the knife. It is heavy which a lot of folks don't like, but I like the weight in my hand, and the ability to smash something with it without worrying I'll damage it! - Terry S.

It's my second otf I've ever gotten, gotta say it does the job well! Action is great and the blade doesn't wobble all too much. A little greasy(?) out of the box but I wiped it off and it was fine. Overall love them both and would order again!

Excellent design and the dedication that Viper Tec puts into these awesome knives is a craftsmanship of art and I would recommend any products that they put out to anyone and you will be extremely excited once you get your hands on one or many

I was expecting this knife to be heavier than it is from reviews from others, but it’s pretty perfect of a weight. The knife slide out seems to be pretty safe from accidentally protruding and the switch button is deliberate. You can tell they cared when designing this knife.

This is the third Viper Tec knife I have purchased. I am impressed with the function, quality, and style of each knife. You can tell it’s a high quality knife just by the weight of it. Very satisfied.
