The Ghost Straight Edge double action OTF (out the front) knife is perfect for those of you who want to carry a full-size knife without the extra bulk.
Like all Viper Tec knives, the Ghost Straight Edge is built for hard use. Each Knife comes with a 3.5-inch 440c blade that have been hand sharpened to an extremely sharp edge ready to cut right out of the box. The smooth ergonomic handles are made of high-quality Zinc Alloy. The button placement along the spine of the handle allows for lighting fast ambidextrous openings right from the operators pocket. The Ghost Straight Edge also allows for right and left-hand users to pocket carry with its stainless steel reversible pocket clip. If that wasn’t enough the Ghost Straight Edge knife also comes equipped with a “battle tested” glass breaker pommel.
The inner workings of this knife don’t disappoint. “Under the hood” you will find all stainless steel precision parts and our proprietary coated high-performance spring. The Ghost Straight Edge comes with our famous ViperLife Warranty giving you confidence and peace of mind.
All Viper Tec OTF knives are extremely safe to operate and use.

better than i thought...great knife
Andrew L.
I had this exact same knife in black and unfortunately misplaced it. I ordered this one on the terrific St. Paddy's special and like it even better than my lost black one. This is my third Vipertec knife you do amazing work!!!☘️
Nathan M.
Behold! One of the toughest and meanest knives ever assembled you'll ever wield.
It's got ferocious serrations; a heavy and cat-like firing switch with a great safety feature which stops the blade from punching through your femoral artery; and it comes out the box with a razor's edge and has a solid pommel for shattering glass or bone.
It makes a great EDC and self-defense weapon which can be fitted with a lanyard for extra security.
I am definitely getting a 2nd one to keep as a back-up or collector's model.
I came STRAIGHT THROUGH Viper-Tec™ instead of a middle man agency.
Definitely worth every penny.
Sutton C.
love the knife but the blade feels loose
James D.
I am always pleased with the quality and durability of these knives. They have definitely exceeded my expectations! Thank you again for designing such nice quality OTF’s. I definitely will be back. Just FYI, this is my 5th purchase. So, that should say something. If you’re thinking about purchasing one, just do it. You will not regret it!
David K.
Love it. Shipping was fast. Would order from again.
Michael P V.

Gary R.
This monster OTF is just Awesome with a 3.9" blade. This knife is solid with a big handle for a great grip to hold. Surprise me Viper Tec, how about a bigger 4"+ blade OTF knife? Again well built, 4th knife in 2 weeks. Thank You.
Ross A.
I have to say, I’m impressed with the overall purchase experience and attentiveness from buying to delivery, it feels like my family sent a package to me.
I love the knife, it’s exactly the way it looks like in the picture and exactly what I wanted, thanks, Ross
Loukas B.
Solid knife! Good quality. Great for the price, fast shipping. Will be purchasing more!
Gary M.
It's a big knife. I knew that when I purchased. So if your into lite pocket knives this probably wouldn't suit you. Now, having said all that it's otherwise a very well made and slick action knife. I went to some lite work with it right away and it cuts well. I'll probably touch it up though because I prefer scary sharp as opposed to good sharp. The serrated edges ( both sides) are for emergency purposes. I did a lot of research and review and am very happy with not only the ghost but the extraordinary and professional service, communications and fast shipping of the Viper Tec team. Good prices too. Well done. I purchased another knife, different model from Viper, little smaller which I like even more.
Jason M.
Love the experience and the product. I was very pleased by the ordering process. Once ordered I received notifications for all aspects of shipping. When I received the OTF I was very pleased. I also love the subscription service. Who would have thought I would get a better OTF from a blind subscription over what I actually ordered! Big fan.
Jeffrey R.
Excellent Quality!
Steven S.
So far so good, I really like the weight, look and feel of the knife, my knife didn't come as sharp as I would expect it to come but I'm sure it will only take a minutes to make it as sharp as I want it to be.
Jared M.
VT stands by there products, I’m very happy
Sam T.
I have a total of 6 Viper Tech knives . 5 operate fine , 1 is broken . I could fix it if I had a screw driver small enough to fit .
Sam T.
Sharp & sharp looking , Good feel , good operation , I'm well pleased !!
Ben S.
Very nice knife
JUAN L.
Well built and extremely tough. The exterior has good grip to avoid slippage. And of course I love the spring assisted blade. Very impressive. Looking to get other models.
Sean H.
A gift for my brother and he loves it!
James P.
Great knife! Took a very long time to get to me and the customer service number they give rings and rings with no answer! They reply via email several days after you email. Lucky for them the knife is very nice. Be prepared to wait on delivery for weeks.
Timothy M.
Took a bit longer to arrive then anticipated, but definitely worth the money.
Mike L.
I’m a Retired Ranger / Retired Detective I was looking for a great combat Knife and was told to buy a Microtec knife unfortunately they cost between $300.00 to 500.00 plus. That’s crazy so I did my research and found VIPER TEC knives there’s no difference and the cost was 89.99 plus tax and shipping. Great knife well built solid and its a 440 steel blade. HIGHLY RECOMMENDED
Brian K.
A+++++ very nice quality
Chris G.

Yauncey V.
Very strong sturdy knife will buy again
Sioux C.
I love this thing! It's got a nice weight to it without being too heavy, and the spring action has great power. It's easy to deploy and retract. I've been using it like crazy! Such a sexy blade!
Jared S.
Good weight, knife comes out an retracts back very quick. Definitely worth purchase an shipping was quick.
Matthew T.
Well quality product at a fair price. With a lifetime Viper Tech warranty, I can have piece of mind that I will be able to carry this knife along time.
philip b.
The quality of this item is better than I expected. The Company went a little overboard in sales literature after my order. I'm happy...

Ricardo P.
I love this blade, this is my 3rd purchase from Viper-Tec and thats because I have family members that bought the other 2 off of me because they liked them so much that they just had to have them lol. All of my blades have been very sturdy, very sharp right out of the box. Best blades ever, thank you Viper-Tec you guys rock making amazing products.
Tyler B.
Shipping process is a little lengthy, but worth the wait. I immediately ordered another product after seeing the craftsmanship first hand.
Christopher L.
This was my first OTF knife. Wasn’t sure what to expect. Very impressed! Very well made. Very sturdy.
Ron S.
Well made and heavy duty otf blade
James B.
Great quality! Heavy duty, glass breaker is a great addition
James H.
The knife itself is way better than I expected. It is sharp, solid and very well made.
I did receive a different knife from the one I ordered, and am currently trying to contact customer service to see if they can help me get this error sorted out.
Other than the small hiccup, the company provides excellent hardware.

Seth K.
Package came in on time but tampered with was missing one knife. I contacted customer service and with no issues they got me situated. Thank you for your outstanding customer service.
Jeffrey P.
Amazing quality and works flawlessly. I’m very impressed with the workmanship.
Rodney H.
After my house burnt I began replacing my knife collection. I was hesitant to buy any OTF knife that wasn’t MicroTech, but decided to give ViperTec a try... & I truly am overly pleased. I ordered two knives & both are fantastic. Quality hardware & Excellent craftsmanship!!! Not to mention I bought two OTF knives for the price of one OTF knife by any of their competitors & the quality is almost identical to any high end OTF knife. I’m all around pleased, I even created a shipping issue by giving incorrect information. With one call & five minutes of one of their associates time, everything was fixed. If you are in any doubt about ViperTec, you WILL NOT be disappointed...
John T.
Website was great! Knife exceeds expectations!
Justin B.
I bought 2 knifes as Christmas gifts. The first was perfect, the second was missing the pocket clip.
I was not happy and I called and sent 3 messages. I made contact by phone and spoke to a rep. who sent me a replacement that arrived in time for Christmas.
Great service and the knife is awesome.
I would buy again!
Ken M.
Ordering was easy. Then ViperTec kept me up to date with frequent emails giving me the status of my order. The knife seems well made and works well. I'm in the military, and this knife will go with me on deployments.
Kalisse M.
I have 3 Benchmade OTF knives and I would say the quality of this knife is primo. It feels very well made and works fantastic. Pretty sharp out of the box too. Shipping was on point and dealing with the company was easy. Definitely recommend.
Chris P.
It's a great knife Any cuts great
Tim R.
Very High Quality Blade
Christopher L.
ALWAYS a pleasure dealing with Viper-Tec. You can get some great products, as I know I have. Their Cyber Monday sale was the best. This knife has been great to have.
William T.
Great knife. I wish they wouldn't take the weeks and multiple emails just to ship it though.
Dean B.
Great knife. Very sturdy and well constructed
Ryan A.
Great price. And great product. Shipping was weird but arrived at before Christmas.
Andrew H.
Got it delivered quick
Nice knife
Bryan H.
Very nice otf
J P.
VERY STURDY & WELL BUILT. Not a flimsy p.o.s. !!!!
Kenneth B.
The spring tension along with the quality make a great combination. Probably one of the nicest knives I own
James W.
This is a robust otf knife. It thrusts out with commanding force. I've had other otf knives that wouldn't penetrate paper if it was in front of it during deployment but I had my hand in front of the viper ghost and it penetrated deep. This pic is my hand still bleeding after applying pressure for 5 minutes. Not mad though, did what it was suppose to but be careful.
Keith W.
I Love the knife !!!
Kenneth M.
Worth the money.
JOHN M.
Love the knife, but my order was for TWO knives.
I know, send an email. Done, no replies. Actually received a text a few days later and was asked if I was happy with my order and again gave the same reply. And again no reply from them.
Very poor customer service, and that's a huge compliment.
Tuan T.
Great knife. It goes even I go. Sturdy. Durable. Very rugged. It seems too be a very high quality knife. Comes out of the box very sharp.
jason m.
Action is crisp and blade is razor sharp. Very pleased with the quality.
BRUCE F.
Item was just as described and was given as a gift!
Shipping was VERY VERY slow! Indicated it was in stock and took 3 weeks to get delivered.
Tyler P.
The tracking number supplied did not work. Took about 12 days to arrive. The knife (grey ghost) is great for the price. The grinds are a little uneven but freehanding the edges of a dagger style blade on a belt grinder is never easy or fun. The action is pretty smooth and snappy. Overall a great knife for the price.
John C.
Not sure how I found Viper-Tech, but I’m glad I did! I could easily spend over $1000 in a session, so I have to have control when I’m on the site.
The Grey Ghost OTF is such an awesome knife! It’s my first quality OTF knife and it did not disappoint! “Under the Hood” mechanics are so tight, amazing quality at a great price! The blade is tight when extracted and no rattle when inside. I got the half-serrated blade and it’s extremely sharp with a surgical point.
The shipping was also extremely good, nice & quick!
Viper-Tech is a quality USA company that makes an excellent knife. There’s no difference between their knives & a $500 knife. I’ve already bought my second!
PS- Sign up for their email list, they have killer sales!
Steven L.
It was a gift to my son he uses it everyday and is very happy with the results
Karl F.
Best bang for the buck! Comfortable in your hand, smooth action. No wobble in blade, everything is tight. As it should be. I have a few viper tech knives. I highly recommend them.
Alden F.
The knife took a while to arrive but I am happy with my purchase. Flies open and closed real quick and feels very solid. Great intro to the OTF world without breaking the bank
Scott W.
Fantastic action. Sturdy as hell. Sharp. Good price. First day I thought I broke it (my fault), but it was easy to fix.

Ronnie J.
Great knife for the price i got another otf knife from another site first (before switching to viper tec) but it broke the day i got it the only complaint i have it the blade is made of 440C stainless steel which im not a big fan of i prefer tool steels or carbon steels but for under $100 this is most likely the best deal you will find for an otf knife/(John Wick knife)
Josh S.
great knife, love it!
Tuan T.
Solid and sturdy knife. I am very happy w my purchase.
Zaid A.

I love it that I end up gift them to my uncle and buying a few more for myself and my brothers
b14ckr41n
This is my third Viper-Teck knife. I got the double side blade because let's just face it they look VERY cool. The only complaint I have ever had with any of the knives is that the blade was loose. This one is PERFECT. Absolutely perfect. You guys have a customer for live. Another great knife, thanks guys.
Jesus R.
The quality means alot to me and the weight says it all .The blade is so sharp it just cuts almost anything like butter and the way the blade shoots out so quick is awsome I'm loving it
