this has suddenly become my favorite Viper OTF. correct length, light weight, and well made. I also got it during a 50% off sale, so even better. It has spent most of its' time in my pocket since it arrived.

VT Falcon OTF Knife D2
Brandon M.
The Small Black Ghost D/A OTF is the perfect pocket size knife with a sharp edge. The pocket clip is well designed and keeps a firm hold inside the pocket.
The button quickly opens and closes without any hesitation or spring loss. It is a solid choice from Viper-Tec.

When I first held this thing and felt the weight I knew it was not some cheap OTF knife. This thing works great feels great and I can’t wait to explore more that viper tech has to offer!!!

First off the shipping was super fast. Packaged safely as well. The knife is sturdy and built well. No problems with it at all yet. Blade could be a bit sharper in my opinion but over all it’s a great knife. Will definitely be ordering again soon.

The knife is a good quality well made otf knife. Works great just like the other 2 I have purchased from viper tech. If I had to make a critique then the color blue is not as bright as depicted in the pic online. Still is a great carry piece.

This is now my favorite Viper-Tec! A super handy way to carry a utility knife. It’s very well made, has fantastic spring action, feels secure in your hand, and the blades are easy to change out. I got super fast shipping too. Thanks!

Nice knife, my second one now from VT. Tanto tip, small to standard size knife. Perfect in between size from a mini OTF and my 8” Black Reaper with 3-1/“ or 3-3/4 blade. This is around 2-3/4” blade, has some nice weight to it. I never thought it could bother me because usually they are not tight enough but this pocket clip is EXTREMELY tight and hopefully it breaks in. It’s literally coming close to tearing my jeans. Hard to pry up out of pocket but again hopefully clip tension will break in and...

It's been awhile since my last OTF,and since then the knifes change for good, in quality ,looks and mechanical movements, they are slim,fast and quiet. Simply awesome.

BEST FREE KNIFE I EVER RECEIVED A little slimmer than the Black Ghost OTF, or Black Phantom OTF, and slightly lighter. It's got a great finish on it, embedded into the metal. Almost a "gold nugget ring" type pattern. Making it easy to hold on to. Great smooth action upon engagement and retrieval. It just feels good when you are holding it. It will give you Joy. Even the chicks dig it. They can't resist wanting to put mine in their hand and play with it. With ease, I might add. No struggling to e...

My Black Phantom OTF has a great feel to it. Like a comfortable handshake. The textured grip adds a great touch to it also. And the tanto blade style is perfect for the job at hand. No matter what that job tends to be. The action is smooth and responsive, with no misfires. And for 50% off? I would be an idiot not to purchase it. And who wants to be an idiot? Merry Christmas to me.

I'm still gonna give it a 5 even though it is relatively dull for a knife. BUT it's a solidly built knife for the price. I like it a lot
Plus it was free with a purchase over $80. Can't beat it

These are the perfect EDC as far as size goes! A 3-inch blade and a lighter handle would be the ultimate but these are pretty damn good! Especially with the app special! Get you some

I have a great appreciation for this pen knife; I found it to be thoroughly enjoyable and would strongly recommend it. I am merely lacking one color to complete my collection, which speaks volumes. Additionally, the customer service is exceptional and highly responsive

This is not my first or second time ordering from viper Tech's website. Amazing products absolutely great knives, but the best part is if you have any kind of small issue or large, by protects customer service hands down the second to none. They are amazing as well. Thank you guys very much for the great knife and thank you for the great customer service it keeps me coming back and I will always recommend you to all of my friends and family

Being that this is my first OTF, I love it! It works the way it should, its lightweight,yet seems to be made well & very durable. If your on the fence about purchasing, dont be. You won't be disappointed.
VT Emperor D2 OTF Knife

Much nicer than my 440 SS model. Mechanism feels solid in and out. Ergonomics is ok but considering it is a smaller knife, that’s not a huge factor. The D2 blade is nice and sharp. Patiently waiting for other models to come back in stock with the D2 steel blade.
Small Apollo D/A OTF - D2 Steel Blade
Hunter K.
Seems great so far, the last inch of the blade slightly rubs on one side when retracted but so far that has not impeded proper function so I couldn’t care less. Very sharp and good grip for your thumb on action. For the price I like it better than any Cobratec. Hopefully she holds up.

Everything on this one was perfect except the pocket clip was way too large so I took the one off the free knife I was sent with the order the mini black phantom!

When I got the knife, I thought it would be a bit bigger at first. Despite it being a mini.
I absolutely love it because it's very compact and can do damage when it counts. I'll probably get another one.

Absolutely. Wonderful knife was a nice surprise. Opening the box and sing the carbon fiber ghost double edge blade. This was my first subscription box that I purchased from Viper tech. But I will definitely be getting more and I won't hesitate to recommend this company to others.

Exactly as expected, expertly crafted OTF knife. Blade about 2 and 1/2 inches long on the double side version, came sharp, sharpened with sharpener and it’s perfect. Compact. Window breaker on end for emergency’s. You can tell it’s oiled and well built. 100% would buy again if needed

2 words.. Bad Ass!! If you’re looking for a cheap, dull pocket knife, this knife is not the one for you. This knife could cut a diamond in an ice storm. Only purchase this knife if you’re done wasting money on all other knives.

The action has been flawless. The blade has shaved me once and cut me twice. Lol. Its definitely sharp. Very heavy and 10" long so it feels high quality. I will come back and edit review at 1st sign of action malfunctioning or breaking .So far so good ViperTec you make a qualitiy product.

This knife is a bit pricey, but well worth it. It is an OTF knife built into knuckles. The OTF part is light and very responsive, and the rest of it is nice and heavy.
VT 1918 Trench Knuckle OTF Knife
Alexander B.
Surprisingly not a piece of shit. This is like a pretty heavy and seemingly well made OTF. 440c at this price point is acceptable, it's easy to sharpen and won't corrode. It came OK sharp out of the box but obviously not like a $400 Pro-tech sharp or Microtech sharp or something. But guess what? It's like 1/4 of the price of those. Would recommend.
Also, it's easier to actuate than a lot of OTFs.
