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

Skyler K.

Love this piece. I was devastated when i tragically lost a butterfly spring for my Benchmade Infidel so this was an incredible replacement. Impossible to beat the price especially for the quality of the hardware. I was worried at first how long it would take for the action to start giving up but for as long as i’ve had it, it still functions like new. Some of the best work around💯

A VERY nice knife! I am super impressed with the build quality and action of the blade, again a very nice knife. Viper Tech folks did me a solid. I will definitely do more business with them.

I was wanting to get into OTF knives not really knowing how to get started. Now I love this class of knives and look forward to each delivery. The action on the knives is excellent and the blades are wonderful. It is definitely worth the money!

Bobby F.

When I received it and opened the box it was a lot smaller than I expected. But as I handled it and worked the action, I realized that this little cute knife was bad as hell. I immediately started using it at work and now I like it better than my old work knife.

Customer video review of 50% OFF Small Grey Ghost D/A OTF (Multiple Blade Styles Available)

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 photo review of Black Ghost OTF Knife - Damascus Steel

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.

Customer photo review of Knuckle OTF (Multiple Styles Available)

Bambi H.

I ordered the Knuckle for my husband’s birthday! He wanted a knife and knuckles and when I saw these I knew I found his birthday present. Delivery took longer than expected but that was not the company’s fault it was the mail service. Once the package arrived I couldn’t wait for him to open it. My husband could not be happier with his Knuckle OTF. I was thrilled it had exceeded my expectations. Great price, awesome design and quality is superb. I will definitely purchase from Viper-Tech again.

Can’t be mad about a free knife. Action is good and the blade is solidly in place. It arrived decently sharp as well, which is a plus. Overall a good budget knife for those looking to get into otfs.

I was expecting to get something else that I wouldn’t be that interested in but after 2 months and 2 fantastic knives I can’t say anything negative. Usually just use them for box cutting but I have used the last one to cut tomatoes and cheeses. Solid knives.

Matthew P.

I love this knife. I’m not a knife connoisseur at all. If it’s durable, feels good, and cuts, I’m happy. I’m a simple man. This is my every day carry. It is used and abused. Always holds up to the test. I now own 5 Viper-Tec knives thanks to their promotions and deals. Customer service is fantastic as well. They reply within hours. I have convinced friends and co workers to purchase these knives. One coworker thought I worked for Viper-Tec with how much I brag about them. They’re just g...

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.

I've had 2 knives over the past 15 years from a very expensive company whose name rhymes with picrotech. Spent over $1500 for both knives. They were great. Great quality, nothing to complain about. But the quality I've found with vipertech matches theirs and more. Solid knife. High quality. Feels great in the hand. It's hefty and doesn't feel like it'll break if you drop it. The blade is amazing and amazingly sharp. The action is so smooth!!! Love this knife.

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.

Bought the mystery box OTF bundle and got two amazing knives. Although they weren't the ones I wanted its easy to could tell that the people at viper tec have some good taste. both knives cut boxes like butter and is my new every day carry for my day to day life.

Nicest OTF I've owned. Sharp blade, addictive and satisfying action and deployment. The blade is pure art. Nicest blade on an OTF. I also love the size and the weight. It feels great in the hand. I'm going to buy another one!

I have to say that I was pleasantly surprised by the quality of this little knife. For the price, I wasn't expecting a lot but the knife hasn't had a single misfire and I've played with it constantly for about 2 weeks now. Vipertek is putting out great quality and workmanship. I will be buying again in the future. Thank you Vipertek.

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...

I tried my first viper tech otf- now I own 4..it is the most convenient knife ive used..extremely durable and reliable-very comfortable in the hand . I think the glass breaker is a wonderful touch. It includes a holster and also a built in belt /pocket clip. I would highly recommend this knife. Once you hold it you can feel how well built it is - very high quality..

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.

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.

This is an awesome knife. It's construction to perfection and works like a dream. It have flawless action ejecting and retracting the blade. This is by far one of the best knives I've owned. I recommend that you add one of these to your collection. Very satisfied customer, Bryan Healy Sr.

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.

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.

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 ...

Benjamin R.

Great feel, I have big hands and this little knife still feels good. It was pretty much exactly what I was looking for. Price was right. Blade has a slight wiggle when extended but shouldn’t ever cause a problem. Also seems like it will let dirt inside easily over time so I will be careful not to take it to the beach.

What can I say. Viper Tech OTF knives are grade A #1. Nice to handle, really comfortable in the hand, very well made. And I have to admit cool and just plain fun to use. I have put this blade through a lot of use as you can see in the pictures it held up amazingly well, pics taken after all of use I put it through. I love this style of blade. My only regret is that this is the only option that I have seen for this style of blade. My favorite blade is a tanto but after getting this blade and usin...

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!!!

Kevin W.

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

Carlos R.

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.
