Customer video review of Free Unlimited Return Valid in US.

Terry F.

I had purchased one of these knives and loved it. It was an early Christmas gift from my wife. When my son and grandson came for Christmas, I tossed it to my son to show him. He said "thanks a million, and put it in his pocket. I didn't have the heart, being Christmas, to ask him to give it back. So, I bought another one for myself.

This OTF is awesome. Super reliable and it also has a good weight to it for the size. It feels real nice in the hand. I sanded the high points to stylize it and I'm pretty stoked on it. Thanks ViperTec!

Customer photo review of Black Reaper OTF Knife

Benton T G.

My first OTF from Viper Tec, is amazing. The craftsmanship, razor sharp blade and weight is incredible. Can’t wait to start the collection of these fantastic blades. Huge fan of the quality and feel.

Michael N.

Wow that is what you will say if you buy one of their OTD knives they are works of art the attention to detail is definitely there. the action is very smooth and it’s a very solid build.. it is extremely sharp. When I ordered it, they were having a 40% off special and so the fact that I got this for around 50 bucks is mind blowing. There are a lot of alternatives out there that are commanding 200to 300 bucks. and the quality is not as good as viper tech great value excellent quality thanks guys ...

Customer photo review of Black Zedd D/A OTF - Damascus Steel (Multiple Blade Styles Available)

Leslee A.

I really like this knife. The Damascus steel blade is beautiful and is very sharp right out of the box. The knife has a good feel in the hand and opens and closes very solidly. I found that a little CLP on the switch was much needed and I'm going to be interested to see how the edge holds up.

Customer photo review of Monthly OTF Subscription

Donald U.

This is the first knife I received from the subscription and am not disappointed. Very nice knife. Sharp out of the box. Only problem is I think it may have a bad spring.. about every third repetition in but mostly on the out it hangs up an you have to flick the knife or grab the blade to get it back in alignment just

Mold making and casting the past few days this little guy came in handy quite a few times. Did a little carving to clean up a few castings - cut a couple simple stencils using it also. Fits right on my keychain making it super easy accessible. =]

George C.

The switch a little tighter than I thought it would be. Maybe a little oil and brake in time might do it good. I like it and I bought my wife the OTF pen which should be called out the top OTT instead of OTF.

Impressed and happy as usual! I’ve ordered about 10 knives or so from Viper Tec as of now. I can honestly say that number is going to increase over time! Love the products, the price points and the company on the whole!

A purchase well made!

Customer video review of Grey Ghost OTF Knife (Multiple Blade Styles Available)

Joshua F.

Very well made. Comes with a case, but can also carry it in your pocket. The mechanism to open and close it is not too sensitive. I don't feel I have to worry about the blade coming out in my pocket. I also tested what would happen if it opened with something in front of the blade. I opened it with this cardboard about two inches away from it. As soon as it hit the box, it stopped. It didn't pirce the box. It just went loose, but you just have to manually pull the blade all the way out to get it...

Wow!!! What an awesome piece!! Well weighted, well balanced and the action is smooth. Not to mention the blade itself is sharp and finished beautifully 👌🏻. Viper Tec for the win yet again!

Customer video review of Black Ghost OTF Knife - Hornet Blade

Joseph G.

This knife is amazing. I absolutely love it. I give it a 9/10. The only reason I don't give it a 10/10 is because I expected it to be sharper that it came/is. I was expecting it to be razor sharp, able to slice a single sheet of paper like a hot knife through butter. But other than that it's my favorite knife I own. It's nicely weighted, balanced, and the quality of the knife is unmatched . Thank you viper tec for this amazing knife!!!

It’s been a great knife so far and looks good. It feels solid and the action is great, it hasn’t had a failure to fire yet. It’s a nice knife and it’s got a lifetime warranty so you can’t beat it. I will definitely be buying a few more knives from them

I purchased several knives for this Christmas. Once they were delivered I opened them up to check them out since this was my first order. I jumped right back on the site and ordered a couple more for myself. The options on the site are great and you can find exactly what you’re looking for.

Customer video review of VT Vector D2 Switchable Knife

Kurt A.

The Viper-Tec Vector is a jewel of a knife. It is a snappy switchblade with surprisingly good quality and feel. It is the perfect size for discreet carry, with a solid pocket clip and a utilitarian straight blade with an effective piercing tip. It is good-looking, too, with a deep groove near the top edge and quality D2 steel.

Customer video review of Black Phantom D/A OTF (Multiple Blade Styles Available)

Timothy P.

I love the knife but sometimes when I open it, it comes off the track and it doesn't come out like it's supposed to. Other than that, I love the knife. I love the grip, it's textured I'm a way so you won't lose your grip in case your hand gets wet, and the window breaker. The pocket clip is nice and tight so it won't come out of the pocket on it's own. I love these knives. All of VTs OTF knives are great.

Matthew A.

Picked up this mini OTF knife from the monthly OTF subscription and I love this little guy! It's the perfect blend of pocket-friendly and stylish, feeling both discreet and deadly. Its grip gives you the confidence of a much larger blade, no slippage here. This little wonder has quickly become my go-to for both utility and flair. Don't overlook this one; it's small but mighty.

Customer photo review of Mini Mantis OTF Knives

Wayne R.

The mini OTF is a awesome little knife. It seems to be very well built and the action is very quick. The best part of the experience is the price compared to other seller's, Vipertech is fair priced and you get a quality product. I already own 3 otf mini's. I recommend buying from Vipertech.

Tim S.

Expected it to be heavier, but not disappointed. It’s made very well, all metal which is great. Love the quick action in both directions. Faster than the human eye! Sharp. The point is ridiculous! Like touching a needle. Life time warranty? Cool beans. Pretty tough though, don’t think I will need it. I love it. Thinking about getting another one.

Anthony Q.

Saw an ad on IG and thought..Oh, that looks cool. I went to the website to check what else was available. Seen the prices and thought too good to be true. Figured I’d try this knife out and figured if it was a scam I wouldn’t be out much money. Read some reviews from others online and thought I was going to be duped. But, low and behold it was sent and at my doorstep within a week. The knife is tough and sturdy and I’m really surprised with the price point. I mean it’s a knife that fits o...
