Happy customer

Just received this beauty a few days ago. All in all it's a great value for it's price point. The D2 Steel blade is razor sharp. The double action is fast and has worked flawlessly. The weight and feel is perfect for me. The only negative thing is that the blade has a little side to play. I will definitely be purchasing another knife from Viper-Tech.

Great product!

Solid OTF with a very well ground edge. I've used it every day since receiving the knife without any complaints. Build quality is clean and precise without any alignment or fit and finish issues you see on cheap Chinese knives. The only problem is that when watching reviews the knives used to have machined aluminum parts but they are now a cast zinc alloy. This gives the knife a hefty weight that is nice to counter the action. But I have yet to see how durable the alloy is since cheaper knives I had that used zinc alloys were prone to cracking if dropped. The lifetime warranty they have should put that issue to rest if it happens.

Got it quickly. It works the mechanism excellently, smooth, stout, not too much wobble, great steel. Better than expected.
Not tested beyond first impressions.. Great piece at the price I paid.

William K.
Absolutely love this knife.Razor sharp right out of the box.shipped in less than a week.I want to order another one.
William K.
Great knife.razor sharp right out of the box.blade length is 3.75 instead of the 4 inch as advertised but that’s ok with me.shipping was very fast this time.I went on line to buy another one because I love it so much but they are all sold out.great knife.you can’t go wrong with this d2 steel
Eric G.
I think this is very well built. Kind of bigger than expected. Smooth action. Use it everyday at work without fail. Plan to buy the same thing only slightly smaller blade length.
Peter M.
I ordered this and the OTF pen. After I placed my order I was told the pen was not in stock so I am still waiting on that. Initial quality seems great. Nice, hefty handle, carbon fiber look inserts, and a glass breaker. The blade is the perfect size. I like the grip I get on this more than my MT UT. I have not put it through any cutting tasks yet but so far it's a solid product at a solid value. I would recommend trying one. You have nothing to lose with the lifetime warranty. Once I receive my pen I will write a review and update on how the apollo is holding up.
Ernesto B.
I like the knife, the OTF slide mechanism is staut slight wiggle at the deployed position however I kind of expected that, its fits my hand well, its ergonomic features are supportive of both handling and deployment of the blade. It will be my EDC.
Tim R.
It’s a pretty good knife, has really good action with a tight lock, normal amount of blade play, it has a little bit of weight to it but stfeels good in the hand.
Geoffrey S.
Good quality,snappy d2 sr
Nicholas E.
I have several knives but this has the smoothest motion. It has good weight and easy to grip. I would highly recommend this knife to anyone looking for a nice quality product.
Brandon A.
Great Knife and shipped fast! Will buy from here again!
Bobby K.
Awesome
Leonard H.
Awesome knife! Excellent blade!
Patrick C.
Even though I've only just gotten the knife I am pleased with the seeming quality and construction of the knife. I am interested to see how it holds up over time and how well I can maintain the edge, which was exceptional out of the box. Even though I have made concessions for the holidays, I feel the shipping was exceptionally slow for this day and age. The communication leaves something to be desired as well. Over all, I am very happy with the knife and glad to have gotten it.
Christopher N.
Works great I love it. I will be buying another one.
Alfred R.
Arrived on time. Blade very sharp. Does not seem to be a lot of pressure as blade extends, seems more pressure as blade retracted. Good weight.
joseph o.
I actually have 2 viper tec otf knives and a third on the way! The first I had a couple issues with. The belt clip screws fell out and the knife started sticking and not fully opening or closing. I contacted Viper Tec about the issues and they said return it and they would repair or replace it. It was replaced with a brand new knife. They stand behind their work!! Great knives and customer service!
Jason M.
Actually a pretty impressive copy of my MT CT! Very solid build quality. Carbon fiber inlays could've been cut straight, but whatever. Makes a great work beater. Fires hard, sharp edge, and makes a great EDC.
William B.
Great knife
Gregory C.
Quality is outstanding & the tension on the release & withdrawal is strong! The rubber grip with the carbon fiber was a great choice for all to enjoy the same way. This is a no brainer & a must buy!
Jeffrey G.
The one in the picture is my daily carry. I have a mini in both vehicles and a full size double edge. Best knives I ever bought.
Ben L.
This is one very nice otf. The weight is compatible to my edc, the Takin. Fits my hand like a glove, is better than a roll of quarters and the striker on the end is not limited to glass. The blade release is perfectly located so I Do not have to alter my grip to deploy. The blade comes out fast with a solid kathunk when set. The blade is stout enough for any task short of batoning. A great all around multipurpose tool. The D2 will get razor sharp and has held the edge with everything I have thrown at it. This is my 2nd viper tec, and there will be more. Cannot beat the quality at twice the price.
Bryan L.
This was my best friend. The love of my life. The best thing to ever come into my life. Last night I got pulled over by the police. They had a K9 unit sniff around my truck. He smelled something "suposedly". They searched my vehicle and found nothing. They took my pistol and this exact viper knife. They said they put them back in my truck behind my seat. They said do not retrieve them until they are gone. Well, when i got home I grabbed my pistol but my love was never to be seen again. DAMN YOUSE, DAMN YOUSE TO HELL..!!!!!
I loved this knife more than my wife. I would trade her in a heartbeat with no hesitation or second guesses.
Jason W.
I experienced terrific customer service. I really like the knife .. Great workmanship. Super happy with purchase.
mark r.
Awesome knife,very sharp and shipped super fast. The weight on this knife combined with the D2 steel should last for a very long time.
Wayne N.
Every thing was fine except for USPS. They were very slow and if I buy another one, I’ll drive down and pick it up.
Luis L.
Very well constructed, good materials and good feel in your hand.
JEFFREY S.
Very good!
Stephen S.
Weight of knife is excellent and action is flawless. This is 6th knife purchase from Viper Tec. Happy with quality of products and customer service; they don't disappoint.
Jeffrey K.
Excellent knife. Very smooth action compared to other OTF knives I have owned. Delivered on time.
Jared P.
Build quality is outstanding, prompt service on shipping and receiving my knife. I will definitely be a regular customer and referring as many of my clients and friends to Viper-Tec
Leland J.
This is a large, solid blade, OTF knife with a substantial heft to it. The action is a bit stiffer than the other Viper Tec OTFs I have. This is a good thing for safety reasons. I've even moved the clip to the left hand side, so that as a right-handed person, there is greater gripping surface for my fingers to grab hold of while using the knife. There is a bit of play at the tip of the blade, but there is also a larger blade than most OTFs, and this makes it more practical for everyday use. It's a worthwhile investment.
Kelly T.
Excellent knife. VERY well built.
Mark D.
Wonderful OTF with smooth excellent action. Very sharp right out of the box.
william b.
A little heavy but very solid. This is the third OTF Viper-Tech for me. And my favorite. Solid action and dependability at a good price. Thanks
Steven W.
Without a doubt the finest knife I have ever owned.
Mauricio R.

William W.

Eddie S.
Best otf I have ever had.
Christopher S.
I bought the Black Phantom OTF from VioerTec and loved it so much bought this one. It’s Made from D2 Steel. Took about a week to get to me as expected since I live across the country. Knife was very sharp, I was able to slice thru papers and shave hairs! Action is smooth and crisp. Has a good weight to it. Feels like quality when you hold it. I’ll probably buy another knife from ViperTec soon.
Thomas S.
This knife is now the main knife I have with me all the time....
It is sleek, fast, and very sharp!!
D2 steel ...it is beautiful on top of great utility...
Tough and rugged great buy for the price....
Scott M.
This knife arrived 4 days faster than the same knife ordered the same day from a different site. First impression is all positive. We'll see how it holds up long term.
Pablo C.
I love the feel of this knife! The quality is top notch and I am looking forward to ordering more!
Troyan T.
Just received my Viper-Tec Apollo- the fit and finish is first class- the action is very strong and it’s wicked sharp- thanks - it’s a beauty!!
Joshua H.
Awesome knife, at an amazing price. Excellent value for the money. I made this my EDC work knife, and it’s yet to let me down. The action is fast & strong, and the lockup is solid. The only negatives for this knife are the weight of the zinc alloy handle, and the textured coating started to flake off the handle. However, I’m not too concerned about the coating bc the zinc handle underneath is painted black. Overall, I would definitely recommend this knife.
Baldemar M.
Love it
Jason L.
I could not be happier with this knife. Build quality is top notch. I have knives that cost more but nowhere near the quality of the Apollo. This knife fires with authority and has little to no play in the blade. I could not be happier with my purchase
Hector D.
Great looking knife works real smooth.
Chin L.
Very great
Carl K.
great knife. the sharpest blade I have received. Little bigger than I wanted,but blade makes up for the size.
Alexander O.
Definitely one of the best OTF knives out there especially for the price point. Sturdy construction and works great, the spring action is strong. My only complaint is that there is a bit more play in the blade than I'd like, and it could of came a bit sharper.
Joshua P.
The Apollo OTD is a sturdy knife! The action is smooth and engages well. The quality overall is great for the price!
J M.
I wasn't sure what to expect as I've had other OTF knives and quite honestly, they were junk. But I couldn't afford the $400 or more knives so after researching and searching I came across Viper Tech. I ordered it and waited patiently, unfortunately the knife I wanted never came. Turns out Viper Tech tried to call me but I didn't answer the phone. So I called them back and was advised the knife I ordered didn't pass their quality control, they didn't feel it was good enough to represent their company so they offered me a knife that was better and shipped it out the same day. Excellent customer service and I'm enjoying the knife I've received. They blade itself seems to be good quality, the action is wonderful and I'll be purchasing another one soon.
Shane T.
Knifes awesome would give the 5th star the spring that triggers it out seems a little weak coming out. I've had it for 2 weeks now I love it so far seems quality!!I use it daily will see how it holds up.
ESTRADA J.
I ordered this knife to compare to my microtech combat troodon and I like it the feel in hand is nice and heavy but very comfortable blade play just only a little in comparison to the Troodon the troodon has m390 steel which keeps a better edge retention but don’t get me wrong D2 is a great steel and also holds good edge retention the switch is nice and smooth and build quality is superb overall for the price it is really well worth the money D2 steel OTF usually go for 150+ US dollars And is way better than those OTF made with 440c stainless steel.
Justin D.
I love viper-tec otf knives and have been really wanting an otf knife with this blade style but this one is out of stock! Please restock if it was not already something you guys are working on!
Junior P.
I just received this knife in the mail today. It's strong, feels durable, the switch is strong, so it won't accidentally open. The blade comes RAZOR sharp . I shaved my face and leg to check, if you like the paper test, it passes it like it's nothing. I honestly might buy another.
Troy R.
Very well made, feels solid in hand and snappy action. Would definitely buy again.
