Blue Phantom D/A OTF

Excellent materials and smooth action. Feels and works like a much, much expensive knife. I will definitely recommend this knife for EDC or tactical. This is my second Viper Tec knife, but it won't be my last.

Very good knife! Very satisfied with all the viper tec I’ve owned

Once again a winning effort in knives. A very well made ,easy to use and shipped quickly.

Awesome knife. The person i gifted it to said and i quote "this is f#@king Awesome!

Nice otf..seems sturdy pretty bulky

These are some of the best knives made . Great quality and craftsmanship.

A great product. A little on the heavy side but exactly what I was looking for

Its the largest of the OTFs I own. Its hefty, heavy and well balanced. The serrations are sharp, and the list of utility jobs this thing could take on are endless. Love it. Wish it came in other colors though.

Love it , but it looks like all the other one's I've received

Great knife! Fast ship.

The knifes inner mechanism is very robust/strong, and the blade is exceptionally sharp. What a steal Viper Tech can afford to provide you! Thanks Viper tech for another great product, couldn't be happier with my purchase!!!!!!!!!!

This knife seems to be a solid knife for the most part. The only thing I don’t like about it is that the blade is a little loose and has some play in it. When you go to cut something the blade moves as you apply pressure to what you are cutting but all in all besides that it’s a pretty decent knife for the money. The handle is solid and so far seems to be a solid knife for the money. I probably will order another knife but hopefully viper-tec will try to fix this issue with this particular knife.

Quality was more then I expected. It compares close to my higher end OTFs. A little be movement in the blade. That is with all except my $500 OTFs.

Wonderful knife! Best knife purchase ever made honestly. Always said I’d never spend this much on a knife but it’s worth it!

Was impressed by build quality and function! Showed it off and friends were impressed. They all wanted one! Hands off mofos! This one is mine

You do what you're told when you're told!

It was pretty dull when I got it. If I want it to stay at the sharpness I prefer I need to sharpen it every other time I open it.

won't get to use it till I get stateside.

Great knife!!! Love the communication they put forth about the arrival of product to my door.

Awesome knife, nice weight, smooth ejection, and sharp as hell!! I have to remind myself however it's got a double edge. Very happy. Thank you Steve

This was a gift 2 a friend who loves knives. It was his first off n he couldn't b more happy Thanks

Coolest knife I own by far. 3 stars. They won't post less than 4. The rubberized finish feels good but you can see the finish wearing off after one week in my pocket. Needs a cerakote finish for a solid 5 stars tho.

Definitely coolest knife I own. All I saw were 5 stars so I wanted to see if they would post a 3. I would've happily given it 5 but there was a problem with the finish as you can see in the pic. The rubberized coating has a great feel but is easily scuffed. I had it in my pocket for a week and it looks like it's been drug thru gravel.

Solid knife

Awesome well built OTF knife. Great work Viper!

Fast delivery and great product at a affordable price.

So impressed with the quality of these blades. If you’re still on the fence about whether or not to buy one, just do it. You won’t be disappointed.

Very well made knife but it took WAY TOO LONG to get it. Received an email saying the label had been created then it took a month for them to actually take it to the post office! And very poor customer service.

First knife I bought and love it! Built well, heavy, sharp, and more then I expected!

I have 6 OTF viper tec all are soild built

Delivery took awhile, wrong address on shipper but it was worth the wait.

Bought this knife for my son. He loves it! The only downfall was the post office took a while to get it here.

Great knife Great quality.

This OTF knife is reliable, one handed convenient & retains an edge better than any knife on the market today!!

I just recieved my Blue Phantom as my Monthly OTF knife of the month and I got to say, I like it! I'm more of a tanto or drop point blade kinda guy, but this double edge with half serated blade has a nice look with the blue textured handle. This blade has a good heft to it, fits my hand nice, one of the larger sized ones. It opens up pretty snappy with a solid lock up, with very little blade play. When you fire it, it isn't overly stiff. The textured handle has a slight concurve to it, so it feels more natural in your hand. I have many automatics and OTFs, some in the 400 dollar range and this feels almost as good as those. Out of the 10 or so Viper-Tec knives I own, I would rank this one in my top 5! Thanks Viper-Tec! Dan

Excellent knife overall. When you factor in the low price, it’s downright exceptional. Even though the blade on this one is the less exotic 440 stainless, it still arrived razor sharp. This is my 3rd VT OTF knife, and I’ll definitely be buying more. The lockup on this one, as with my other 2, is solid, and the action is fast & strong. The only “negative” about this knife, is the heavier weight of the zinc alloy handle. Keep up the excellent work, VT!

Great knife!

Very positive action and lick up . Heavy and large sized well constructed.

Love my knife! Well-made just wish I would’ve known it was illegal to carry in my state matter fact a lot of states

Been wanting an otf for a long time and it was definitely NOT a let down! Best knife I've ever aquired. I can't wait to buy/attain more. I also trust this site.

Plenty sharp. I use it mainly for breaking down boxes. The mechanics of the blade are smooth and solid. Just make sure to clear debris from the blade before retracting.

I love it. Exactly what I needed at a price that didn't break the bank. Shipping was fast. I will be buying more different styles.

Very nice knife and sheath, Nice smooth action, A little heavy but not to bad, Looks to be a very high quality knife and I love the Blue ! I would defiantly buy again

This is my first viper tec knife blade deploys fast,easy return. Other reviews are spot on. My only negative would be the quality of the slide switch. Not the best of quality, lots of rough machine marks. Time will tell how all will work. Like the color, you will know if this falls out of your pocket. Thanks

I really like this knife. It has some weight to it, but I don't mind. It gives some extra force behind the glass breaker. I actually feel no difference in weight in my pocket than any other EDC. Blade is sharp, very sharp. I personally like the weight and size, being i have larger hands. Action is solid and quick, although a bit of force is needed to activate. Was a little iffy about the blue, but I like it a lot. Definitely worth the money spent on it.

Weight and size good as it fits comfortably in my hand.

Very pleased with the overall quality of the knife.

Have bought many knives from viper tech. By far my favorite one so far. Perfect weight the Blue looks amazing. I’ve always wanted a double action but didn’t want to pay a Fortune for it.

These knives are of good quality and have very little blade play I so pleased with my purchase that I signed up for the OTF monthly club.

Waiting to receive the gorilla case that is supposed to come with this set, but I am just glad they were able to get me the knives i ordered so quickly! Especially after the insanely discounted deals they had on cyber monday as well as it being holiday season, i imagine they are very busy, yet my order still came in a timely manner to say the least. I got a quick response to my email saying they would send me the gorilla case after the holidays upon me letting them know it was missing and i told them i was in no rush to get it. I ordered this set as well as the blackhorn stilletto. I would just like to say that I am VERY IMPRESSED with the quality of the knives in this set! Ive only had them about a week or so, but both of these knives seem to be extremely well made. I am impressed. You wont find knives made this well for a better price, I can almost guarantee it. Would definitely recommend this set. Idk if ViperTec makes the stilletto as well, as it was the only knife of the 3 that had a “china” sticker on it and didnt seem to have the level of quality as the two knives in this set, but that may be because it cost a lot less. You cant expect to get the best knife/stilletto for only $40, so I understand. I bought the stilletto moreso for aesthetic reasons anyway, so overall I am happy with my purchase. The stilletto is still a cool knife even though tis not as well made as these too. You get what you pay for, unless its cyber monday, then you get a bit more from these guys. I would highly recommend this set to anyone looking for a couple of nice switchblades who dont want to spend too much money, yet also want a quality knife. If youre looking for a stilletto and dont want to spend a lot of money, you can get the blackhorn stilletto for only $40 here. There are better quality stillettos out there IF you are willing to spend a bit more money, but for $40, I am happy. I am glad i bought my switchblades with ViperTec.

Had issue with springs on blue phantom but the warranty covered the issue promptly! Great products and great company to buy from. Thanks again!

So I haven’t had the knife long enough to write a great review, the knife feels phenomenal. I actually purchased it for my wife and she carries it in her purse. It doesn’t get messed with really at all but she does love it. The only issue I have with this company is, it took over a month to receive it. I called and they stated they were waiting for handle materials to come in. So then it’s not in stock.

I love it. I like bigger knives, with some weight to them. I am thinking of my next selection.

Little heavy but I like it

Great knife! Very sharp

Awesome knife. I love it will be getting a new one soon

Good looks love the color. Nice sharp blade

I love this the full size of this blade in this k ice. The action is very smooth and the blade is very sharp.. I used this knife in cutting rope, opening packages asxnd cutting electrical tape. I was very surprised how well it hold up. I recommend this knife to my friends

I'm new to knife collecting and what knowledge I have comes from reading websites to learn about steel, EDC, Auto, Fixed,Tactical, camping/hunting knives, etc. And what a knife owners expectation should be of the different knife styles. I bought this knife for three reasons: Blade length, price and I've always wanted to replace the switch blade purchased 30 years ago in Tijuana, only to have it stolen by a hooker in LA a few months later. This knife fits the bill for me.

A Very solid OTF and well made smooth action on opening I think you will be very Pleased!!

The first OTF knife I purchased was the Reaper, had problems with it locking into place, I sent it back and they sent a new Reaper along with another free knife to make up for the hassle. Well, the 2nd Reaper did not work either... After calling them they offered to send me ANOTHER knife @ no charge, even said go to the site and pick any knife I wanted. My response was, just pick me out a good one and send that. They did just that... SENT The Blue Dual Action OTF. THIS KNIFE IS INCREDIBLE!!!! Has a longer blade, it's not bulky, I could go on&on. Looking for a great knife get this one. If you have problems call Viper-Tec....they went above and beyond....and now I am no longer CONCERNED!

Very well built feels very rugged. Works very well and very sharp

At the risk of not sounding original, This is an awesome knife. It just satisfies that tactile urge. I enjoy it more than I ever thought.

Awesome knife! Well built. Would definitely recommend.

Amazing knife. Smooth function. Sharp as hell. A little more play in the blade when open than I usually like, but nothing out of the ordinary with OTF knives. Would def recommend to others.

Awesome blade enjoy every second of it

Well made knife but a little too heavy for everyday carrying

has a good feel good lock up outstanding knife

Very nice action- quality blade and fits my xx large hand perfect!

I have wanted a dual action knife since I saw one a while back at the local gun store but theirs was over $400. When I found the Viper Tec knives I knew I had to have one. I am so happy with the Blue Dual Action Phantom I purchased! This is a great quality knife and the weight feels great. It is not a cheap thin knife. You could knock someone out with the weight of this knife alone. Would recommend to anyone who wants a dual action knife.

The style and craftsmanship is perfect. It’s my daily carry knife now. I would recommend it to anyone.

Great knife!! Nice hefty feel. Crisp action. Excellent edge. Exceeded my expectations. As good as if not better than some OTF’s I checked out selling for $250 and higher. Highly recommend and will be buying again.

Well built. Seams sturdy. Compared it to other of the same price range and some even higher. The viper Tec by far exceeds my expectations. My first of many. My wife loves hers. Will be putting this little beast to the test soon and see what she will do.

It’s a nice piece crisp open & retract. Blade locks solid. It’s what I expect. Like the serratedon one side blade.The only reason it didn’t get 5 star is I’d like a little color on the blade

This was a great knife for the price. Has kept its edge & im hard on knives. I use them daily. Only two negatives, it’s very heavy & it needs more strength coming out. I wouldn’t hesitate to buy again. Shipping & customer service was outstanding.

Great knife very well build I will for sure recommend to friends and buy more thank you guys for a great knife

I love the knife, but two or three of the screws that hold the frame together have fallen out and been lost.

Sharp, flashy nice show piece

Best knife I ever bought and it's sharp, really sharp right out of the box

Cool stiletto, very good product for the money

I found the product to be all it was supposed to be thank you

Love the items dill purchase more in the future.

Both knives we received where exactly what we wanted
