The VF-1 Double Action Out The Front Knife features a 440c Stainless Steel blade. The blade can be quickly deployed with the ambidextrous sliding button. Pushing forward on the button deploys the blade out the front of the handle and pressing backwards on the button retracts the blade back into the handle where it is ready again to be deployed at a moments notice. The 3.25″ blade comes standard with an aggressive partially serrated edge giving you tearing and cutting power making it a great all purpose blade. The blade is exceptional at both piercing and slicing due to its shape. The handle is patterned for non-slip handling in any environment. The metal pocket clip is reversible and can be carried in the button back or button front positions. When clipped into the pocket it has a nice low profile “ride”. The end of the knife features a glass breaker pommel designed to shatter glass or break anything else you might need to in case of an emergency.

It took a while to get it but the tracking was great. Once it shipped they were on point from start to finish. The quality was excellent for the price. I have purchased from Viper Tec before and will purchase again

Very sleek, very sturdy, and mechanism performs as advertised. Blade is sharp enough to cut a slice of paper. Way faster than a stiletto.

This is a great knife. The construction is great, the action is smooth, it looks nice. The service of Viper Tec is fantastic. It came way faster than I thought it would. I would highly recomend their products and this company.

The weight makes it fell like solid in the hand and the opening/ closing is very quick and solid. I look forward to my next purchase.

Gary R.
Love the design pattern cuts on the handle body frame on the medium VF-1. Will purchase a full size VF-1 when it becomes available for addition to my collection of Viper Tec knifes. Action on this OTF is smooth and quiet. Love it. Thank You.
Christian R.
This is the second Viper Tec knife I bought within the last few months. Overall I really like how it feels in my hand. The only reason I gave it 4 stars was it didn't feel like it was sharpened like the first one I received.
Gabriel R.
Good knife love it has a little weight to it and smooth
Jimmy G.

Erick D.
Great Knife ! Great steel . Just a terrific knife . If your thinking about it getting it , get it ! Worth every cent and shipping was supper super fast .
Jacob S.
Unfortunately, when I ordered the ViperTec VF-1 D/A OTF in Medium Grey the item was in stock and I was able to add it to my cart. After waiting for about a month for an order update I was eventually contacted and informed that the item was delayed/unavailable. I was offered the same item in black as a substitute. I accepted because I had already waited so long for something that I thought was available. I like the knife, but feel that the website ordering process let me down. Customer service was good, and was able to mail me the substitute with USPS priority shipping, and I received it quickly, finally.

Love the knife. The team worked through a problem on their end and I was pleased with the transaction. Will buy from again. AAA+++
Cameron R.
I ordered the knife as a Christmas present. Did not receive the knife for over a month and a half. Double the amount of time advertised. Knife is great quality! Customer service didn’t respond to emails for over 4 days at a time. Also ended up having to switch the knife I purchased due to them being out of stock. I hope my next purchase with this company is a better experience. Again product is great!
Dennis e.

Jay B.
Love the knives, however, the shipping process takes FOREVER and customer service seems non-existent.
Adam D.
Ordered tanto blade but it came with the spear point blade. It was a gift tho so didn’t matter much. Slightly disappointed in the mix up but the receiver loves the knife
Jason O.

This is my 2nd knife from you and I didn't get an order confirmation email either time. I also sent emails both times and nobody ever sent the confirmation either time.
Michael G.
Love the knives. Great quality and fast shipping.
Rex W.
This is a very well designed and made knife. The attention to detail is next to none. I don’t pamper my knifes and this one is no different. I have put it through everything, I use it every day for work. Thank you
Justin P.
This is the second OTF knife I've purchased from Vipertech. Very pleased with their products. Would recommend either one. Function great.
John H.
Feels good, looks good, works GREAT!!!
James W.
Excellent knife for the money. I'm currently carrying it everywhere using it multiple times a day. We will see how long it holds up. So far so good.
Jeeson C.
Great light weight fast action knife, sending as a gift as i own 5 other products from viper tech, giftees will become new customers!!
Richard H.
A Medium size knife that fits in my hand quite comfortably. Very well designed. Excellent weight to the knife, feels trust worthy. The blade snaps out and back strongly. Knife blade needed a little bit more sharpening, but holds an edge very well.
Vanessa G.
Got this as a gift for my husband and he loved it. The action is addicting. Quality appears to be good. Size is as described.
Thomas M.
Far exceeded expectations! Seems to be very well made, action is strong. The quality combined with the warranty is next to none.
James W.
Great knife for the money. The action is crisp and firm. This knife isnt as heavy as people make it seem. I carry it all day in my pocket and can hardly remember its there. Its a little small for my hands but this was the only model available in a Tanto when I ordered. The blade is sharp and cuts clean. The overall finish on the knife is very nice for something in this price range. I'm currently using it in an Every Day Carry situation to see how well it lives being used almost constantly. I'll reevaluate this in 6 months or so to see how it holds up
Rex J.
Just the right size, though a bit heavy. Sharp right out of the box . Very well made
Richard J.
Really like the medium size, great handle, fits hand naturally. Switch and action seem to work great. Like the Quality, good edge on blade.
John K.
Works great. Love the weight, has substance to it and if I hit someone, it fits in my fist perfectly. Bought them for my supervisor for an early Xmas gift and they all loved them. Got three more of order, didn't see where to put the CAMO gift code, so I hope I get the free blade with my order.
William E.
love this knife.
very well made durable, light.

Another great knife. This is the best one I've got yet. Very tight blade. Great action and a altogether gorgeous knives. Thanks guys.
b14ckr41n
This is the second knife I bought from here. The blade is a lot tighter than the Venom VT I got last time I don't know if it is because the Venom was a dual edge and this is a tanto. I'm not familiar with nice Otf knives all the ones I've owned in the past were cheap ones. I was always taught one of the ways to tell if a knife is great or not is the tightness of the blade. This is a great knife and I had to buy another along with the tactical pen. My next is another dual edge. [I can't help it I love the way they LOOK!] ANOTHER GREAT KNIFE. Thanks guys.
Guy K.
I like the action very fast in and out with a strong spring ! So it’s nice for Deep pocket you can’t even tell it’s there , and it does come very very sharp ! Very happy with this knife
William J.
Nice sturdy knife
Charles R.
Great knives but your shipping sucks!!!
Chuck S.
This OTF is just the right size for me, works every time I have used it.
This is my 3rd purchase from this company and they have shipped it to me within a week each time.
Trampas L.
Fun knife looks and feels good and work's awesome I'm Happy with it and love showing it off. I would buy again.
Louis C.
This is the second Viper-Tec knife I’ve purchased and they’re great. They come with a decently sharp edge, but nothing that can’t be improved upon a bit. The action is tight and responsive. I’ve only had a few mis-fires which are easily fixed, and that’s on the old knife (over a year old). This new one is clearly improved in some way because the action is flawless; no mis-fires.
Legitimately my only issue is the constant 20%~ off offers I keep receiving. My wife has me trained to bargain shop, but I’m gonna go broke buying these knives. And I’ll be damn happy doing it.
William C.
sharp an works great
Thomas S.
Quality EDC working knife.
Russell S.
Love the product and the discount I got for cyber Monday! I recommend them!
Daniel W.
Love this knife.It is very useful and it came pretty sharp out of the box. Only down side to it is that it’s just tiny bit heavier than I thought but other than that I love the size of the handle and the blade design.
Ryan P.
It is a well made knife, solid otf system. Not as sharp as I would like but I can sharpen it up at my house. Over all very good and I like it a lot.
Bret D.
Well balanced nicely weighted and very durable knife definitely one of my favorites in my collection
Marie R.
A nice solid made knife, has good solid action both directions.
Marie R.
A really good knife especially that I got it for free. Came pretty sharp with good action
Matt H.
Great and very sharp out of the box
Josh F.
I originally bought this one to give to a family friend for finishing his eagle project but ended up keeping it for me and giving him the solid black instead. Smooth action as always. Weight is good and just the right size to have in your pocket and not feel weighted down like the full size.
