Customer photo review of Monthly OTF Subscription

Moises C.

This is an awesome OTF! I tried the monthly subscription not sure how it was going to work out or the quality of the knives. WOW! I can't believe the extreme value of this subscription service. I'm hooked and will be ordering more and it has made its way into my EDC. Thank You Viper-Tec for the great knives at great prices.

Customer photo review of Krypton Ghost D/A OTF

Jason M.

This is the 3rd viper tech knife I have purchased and I have to say it doesn't disappoint. Great quality and the smooth motion when activated holds true to the quality of viper tech knifes.

Reviewer's Black Zedd D/A OTF knife with its double-edged Damascus steel blade extended.

Kenneth E.

The double edge Damascus blade is sharp and the knife feels very solid. This is the first Damascus OTF knife I’ve ever owned. This knife will be added to my collection of knives that I keep as “not used” in order to preserve them.

Great knives, if figure they offer the cheapest but no they gave me 300 dollars worth of cheesecake slicers. Great product keep up the good work. So nice I ordered two boxes this month

Nice action, great finish. Viper is a good business that has customer service skills! (I made a purchase mistake and Viper responded with the refund in an above average time frame).The gray-blue finished exterior, with the brushed finish on the silver Blade is excellent to the feel.

Christopher S.

This is my first experience with an OTF knife, so this will be the standard that I have for a quality budget blade going forward. Pros: Overall size, grip, blade sharpness, blade thickness, pocket clip, glass breaker. The size is great, and it fits in my hand well due to the diamond sections on the grip which give me a more confident hold. I really like the blade thickness as well the blade style, pocket clip and emergency glass breaker. Cons: Tight action on blade release button. As I stat...

I absolutely am loving vipertech knifes as I definitely had my concerns to begin with but after getting and using my first vipertech knife they are very durable just as nice as otf knifes that cost double sometimes triple the price I wish they did use something a little better than 440 steal but that would aslo make the price a lot higher on them as well and the 440 actually does very well it stays decently sharp and is definitely easy to sharpen back up after heavy use. All around they are grea...

Dale B.

This knife is very well made. It has some weight to it and with the stainless steel insides it should last a long time. The action is very nice. Glass breaker at other end of handle too. I'm very happy with this knife and have recommended viper tec and this knife to friends.

Mike D.

Love it, i already own a full sized Blue Ghost and i love that knife too, great quality and reliability. Only think i didnt like about the blue one was the rubberized grippy finish, after using it for multiple years every day the finish has chipped and peeled off on only one side. But with this one they seemed to have changed the finish to an anodized finish this one will hopefully not chip or flake off it seems. Great little knife especially for the 50% discount i got it for. Would recommend.

Customer video review of Black Ghost OTF Knife - Hornet Blade

Thomas W.

The knife is overall awesome! The only downsides was that mine came dull but was easily sharpened at home and also some of the black paint came off the very rim of the tip without me doing anything to it. So other than that it’s great

Robert A.

These knives are great. The scale without the clip has plenty of room for laser engraving, which makes them great as gifts, I bought five of them. I appreciate the weight of the zinc alloy scales vs aluminum scales from competitors. The ball bearing window breaker is a nice touch.

This is an awesome little EDC knife that fits easily into you pocket. The action on this knife is so smooth and easy to operate. This is my 2nd Viper Tec knife and won't be my last purchase.

This is my 4th knife from Viper Tec and by far my favorite! The action is incredible and easier than others. My wife wants one now too because it's not as hard to open as the one she carries.

Love this baby. Fits perfect on my mole which is on my Iron Infidel water bottle. This thing is psycho sharp and the action is amazing. I'll never use anything again but the Tanto blade!!!! Keep up the outstanding work. When I'm in the gym ya can't even see it as the handle blends right in.

Customer photo review of VT Mini Stinger OTF Knife

Daniel H.

I was a little skeptical about the size of the knife but I have really enjoyed it. It is a good size to carry around anywhere and it is light. My only complaint is that it does not come very sharp.

VT Mini Stinger OTF Knife

Ryan W.

This is my first experience with an OTF knife. The size and materials all seem great. There is a tiny bit of movement in the blade when it's out, but I expect that to be normal with this style of knife. The blade is sharp and will be a nice little blade for what I need it for. The mechanism is also very smooth.

Mark C.

So this is the 1st knife I’ve received after subscribing to the knife of the month club. I love it! It fits nicely in your hand, has a great texture and the action is super fast and solid. I really like Viper-Tec. I think this is my 7th OTF knife I’ve purchased and this one might be my new 2nd favorite. The black ghost is #1. 2 thumbs up for viper-tec. Great company that I can tell you from personal experience honors their lifetime warranty.

Lubec B.

Great OTF. Viper Tec offers a good value for a quality OTF. 440 blade steel is a decent steel, and works well. If on the fence, come on over and get one. Cut open your Amazon packages like bad boy! Chicks dig it!

Great little mini knife, got my new desert storm and quickly put this one on my keychain, if anyone needs to tighten the screws the mini mantis is I believe a Torx 6 and the desert storm is a Torx 9.

Charles S.

Top notch customer service. I thought I ordered two tanto mini phantom knives. At a buy one get one free deal. They sent me a double edge and a tanto. I emailed saying my state don't allow double edge knives and this could jeopardize my concealed carry permit. The very first email they responded with was the tracking number for my tanto replacement no questions asked. Im only a week in so I can't speak on durability but they run Smooth and fast and are sharp as a razor and feel grea...

So far this knife has been great, better quality than I was expecting. It has a nice heavy metal feel to it. Sturdy. I use it both at work and as an everyday carry. So far I haven’t had any issues with it.

I spent a lot of time looking at different brands, reading reviews, watching YouTube videos before I decided to make my purchase. I don't regret it. I can feel the quality when I hold it. Action is strong, weight is nice, and the warranty gives me a piece of mind. I hope to get the pen next!

To be honest I was not expecting this knife to be as good as it was I bought the smaller one to just see how they were and oh boy live it will be purchasing the double edge grey ghost next these off knives don’t let you down

Bobby F.

You always look for better than the last. With this one, as with the last one and the one before that and so on. This one surprised me again as with all the one before it is very nice and very well built. The action is really smooth and easy and let’s not forget how sexy this black ghost is with this amazing blade. With this blade you get the best of both worlds the straight edge you have smooth cutting and smooth slicing, with the serrated edge you can make some rough cuts with ease. Don’t take...

Pretty good OTF, nice sharpness to the blade. Screws and glass breaker were a little loose but I was able to tighten those up with a Torx bit. Activation switch is not too loose or too stiff. Definitely recommend getting one of you haven't done so.

James S.

Love the quality and double action of these blades. Been looking for a certain one and feel as the one I had from my time in the military and had lost my knife in Afghanistan. So it’s been a long time since I’ve had that identical feel and Viperteck has done the impossible and made it happen… Thank You very much !!!

I love my vt slugger it has a very strong action, very wide, thick blade its not long but it is still very qaulity. I love all of the viper tec blades I have reviewed the paint on the handle could be much better on all of them but im not mad at all!

William M.

What a great little knife! It’s non obtrusive and doesn’t take up any space in my pocket. Takes a little effort to work the mechanism, which I’m totally fine with as I certainly don’t want any accidental discharges while carrying. An absolutely solid knife for the price and size!!!
