This brass knuckles switchblade is absolutely awesome. The design is sleek and solid, with a sturdy brass knuckle grip that feels great in the hand. The blade is razor-sharp and deploys quickly and smoothly with just the push of a button. It’s a perfect combination of practicality and style, whether you’re adding it to a collection or using it as a versatile tool. The craftsmanship is top-notch, and it’s clear this piece was built to last. Just make sure to check your local laws before carrying it around. Overall, a fantastic purchase—highly recommended!

MY ONLY EXPERIENCE PRIOR TO RECEIVING MY VIPER TECH KNUCKLE OTF BLADE WAS WITH MY SON'S BENCHMADE AUTO AND I DON'T REMEMBER THE MODEL BUT IT WAS A FINE TOOL AND HE PAID WELL OVER $300 FOR IT. SO, WHEN I SAW THE VIPER AND THE PRICE BEING LESS THAN $200, I WAS A LITTLE WORRIED THAT THE QUALITY OR THE MECHANISM WOULD BE INFERIOR. BOY, WAS I WRONG! THIS BLADE IS EVERYTHING YOU'D WANT WITH AN OTF AND WHEN HOLDING IT WITH YOUR FOUR FINGERS IN THE KNUCKLE GUARD, THE EASE OF GETTING THE BLADE OUT OR IN IS LIKE ONE THAT WOULD COST FIVE HUNDRED DOLLARS EASY! I'M SO GLAD I SAW AND ORDERED IT. A GREAT SELF-DEFENSE WEAPON AND IT'S SO EASY TO CARRY.

I had ordered before xmas and it took over a month to get here. I had ordered the chrome one, which i preferred, but got the black one instead. Its very well made and solid so that makes it worth it.

Bada** viper Tec knuckle otf
This knife is a lil bigger then I thought it would be. Heavy but carry able! This wasn't bought for daily carry anyway. I was sent the wrong knife at first but 48 hours later the right one was sent to me and it came quick. The otf slide push button is kinda hard to engage but think it will loosen with use.
Jimmy D.
Well you guys sent me the wrong knife but with a email it was rushed to me a day or two later! This thing is a lil bigger then I thought and my push button is a Lil tight . But all in all great knife! This was one of my gotta haves and it was sold out and I found it here!!

Knives
Great
Strong tough and durable capable of doing all the jobs needed
Shane L.
I have to say I have had these for a few hours and already love them they are very sharp and have already helped with cutting into plastic and carbon fibers for work at home they have still kept there edge even after cutting that type of material. The strength of the knuckles themselves are extremely durable and I will have to say that they will last for a long time and take a lot of abuse from hitting or even cutting, I will be back how ever to buy more from blade city as long as they keep getting in newer and greater products such as the spear that I have been waiting for. But these knuckle knife I will be using for a very long time. Thank you blade -city
Jason H.
Very high quality. I love it.

Randy A.
Absolutely love it, the function and durability is great and well worth the price.
Ryan R.
I gave a 1 star review because I thought it broke and I didn’t know how to use it. It’s a good knife but I wish the belt buckle clip was on the other side of the knife because the way it is now is harder to access from your side
Howard N.
Smooth operation. A real asset in self defense.
Mike C.
Very Cool Knife!
This is an awesome knife. Not very practical to carry around, but very cool to have and show off. You get two for one, a OTF knife and brass knuckles. Viper Tec make a good quality knife. I recommend this knife to anyone who wants a cool knife to show off.
Isaiah V.
Strongly recommend I love it
Daniel A.

Michael L.
Great knife
I love the knife just hated how long it took to get here
Ariel L.
Great knuckle knife
The Viper Tec knuckle OTF is great for my big hands, finding a good knuckle duster for me to get a good hold on or comfortable for my fingers to fit on is hard at times. So very pleased. Good automatic knife that you don't have to take off hand to open.
Salvatore I.
Just received it heavy duty ! Feels very solid the action is smooth about 6-10 lbs of pressure required to active the knife so I don’t think it will fire on its own
Jason H.
Independence day slowed shipping.
The Viper-Tec knuckle switch blade exceeded my expectations. And the pelican style water proof hard case it came in was totally unexpected and ...well...badass!
Will definitely do more business with y'all in the future.
Thank you!
