Thank you for sending this solid OTF knuckle style knife. It is a nice addition to the other knives I have purchased from you. Shipping was almost as fast as the blade coming out the front :)
Kevin P.
Looks and feels awesome. Solid weight at almost a pound. The blade could have come a little sharper, but the mechanic
aspects of it are 10/10

LaVerne H.
Wow awesome quality and more knife then I expected
Tony W.
This knuckle OTF is absolutely AMAZING!!!
The quality and construction is without question, the top of the line!
I've ordered two already and I'm going to order several more to give to my daughters for protection and some to my crew leaders in my business!
I absolutely LOVE these items! If anyone would ask me if there needed to be any changes to be made, I would say "DO NOT CHANGE A THING!!!"
If anyone reads this and buys one or dozens, YOU WILL NOT BE DISAPPOINTED!
THE PRICE IS RIGHT AS WELL! I personally own about 8-10 OTF Viper Tecs and I'm 100% satisfied! TO VIPER TEC: MAYBE THINK ABOUT MAKING A FULL STAINLESS STEEL ONE FOR THOSE OF US WHO GO SCUBA DIVING, I WOULDN'T BE WORRIED AS MUCH IF I CAME ACROSS A TIGER SHARK OR EVEN A GREAT WHITE IF I HAD A STAINLESS KNUCKLE OTF OR A STAINLESS OTF. I TOOK ONE OF MY SILVER OTF'S WITH ME THE LAST TIME I WENT DIVING AND I DIDN'T RINSE IT OUT QUICK ENOUGH AND IT'S FROZE UP INSIDE FROM THE SALT WATER....JUST SOMETHING TO THINK ABOUT! THANK YOU VERY MUCH!

Very fast shipping

I enjoyed the three items in this order. The only negative comment I have is it took over two months to receive all three items. I paid an extra fee for immediate shipping, but did not start receiving them for months past when the orde was made. Also, prior to this order, I made another order in the first week of November. I purchased a full size, black double edged OTF ghost. After two or three times operating the knife, the spring mechanism has completely failed. I would like a replacement please, and I can return the broken knife. So, in order to have a pleasant experience, I would need a refund for purchasing 1-3 day shipping and a replacement for the broken knife please.

Wow by Viper-Tec has really done it this time. 2 in one weapon, solid made brass knuckles with the blade to extend. this is a great purchase a must have for your collection.
Albert C.
Seems to be well made.The finish on the edge of the knucks is already rubbing through to the white metal under the black top coat.Will not change the usefulness of the item.I'll use a sharpie pen to fill in the spots that need it.I will buy again.
ERIC J.
Nice heavy and can pack a punch!
Scott H.
Its definitely a beefy piece but I like the weight of it!!! It operates perfectly and have had no malfunctions. Comes sharp right out of box and no reason this knife shouldn't last for a very long time...I love it and would recommend this item to anyone!!!!
Jimmy G.
Item I purchased I fantastic! I highly recommend
scott w.
Very sturdy. Nice action on the ejection of the blade. Well worth the price. It is a present for my niece. She can keep it in her purse just in case.
Bobby F.
Nice easy hands on grip with firm smooth quick reliable push switch button. Impeccable, unprecedented blade sharpening. Very high quality materials and craftsmanship in every product that I own from ViperTec. Worth every penny.

Danny L.
My favorite knife!
Samuel R.
Great knives ill recommend this knife to anyone.
Markus H.
This is a solid knife. The handle was a bit too large for my hand but it still had a comfortable feel. The blade action was spot on but I also felt like if you tried throwing a punch with the blade open, you could catch your own face. Overall, it's a nice weapon, just not for me.
Kerri G.
Amazing, solid, and smooth action
Michael H.
Function amazing, and feels great in my hand, the action is quick and smooth overall it is a good product.
Doug E.
Seems well made, nice heavy feel to it. Blade function crisp with no hesitation.

This thing is amazing I really love it. Built like a brick sh*t house! This thing is serious! Auto is smooth in and out no problem and this bad boy has some weight to it also. I am completely 100 Percent satisfied with this product and everything about it and I tell everyone about it and everyone I show it to absolutely loves it. Must have! If you are thinking about it just do it. So worth it
Jason V.
Great knife, built really tough, and has a great feel in the hand.
Kevin F.
Bit bulky but pretty slick
Antonio G.
This thing is bad ass. Heavy, feels good in your hand, and build well. Definitely would change some dip shit's mind about fucking with you...it's nasty.
Thomas M.
Very pleased with Viper Tec's customer service and the timely delivery of their product.
I would recommend Viper Tec to anyone in the market for quaility knives.
Holly S.
No BS.
Its an awesome knife.
Love it.
Legrande M.
I like it, fits good.
Larry B.
It’s a fine knife I love it
Matt C.
Love it. Perfect for my bugout bag.
George K.
For me it is slightly bulky, but it's a good product. I mainly got it for how it looks. I have no practical use for it as an EDC. Its oldly intimating.
Nicholas L.
This weighted, OTF knuckle is a perfect add to your collection. Quick and quiet with the action of the blade, and on the heavier side sporting an intimidatingly, brutal knuck plated with zinc alloy. Both put through hard use, both still functioning properly. 10/10 would highly recommend
David D.
Really cool but BIG. I’m 6’4” and it fits me but definitely not for lady-hands
Raceguy239
Very nice knife a bit chunky in the hane and I have big hands. But it didn't take long to get use to it. Smooth and well put together. Great item
Russell C.
Hi guys, received my knuckle duster knife the other day and have to say, this knife is heavy duty!
I like that it didn’t come very sharp as I like to hone my own blade, thanks for a quality product!
Ronald S.
Heavy duty reliable knife!
Rohan S.
Great functionality
William C.
GOOD heavy duty knife, any part u touch is heavy duty, iam really impressed with this.
JP
Quick shipping and it is very sturdy. I love this company
Mark L.
Good quality fast shipping
Christopher L.
What can I say? It's basically brass knuckles with a blade. How much cooler can you get? Realistically, it is a bulky piece but if you like collecting cool stuff I doubt you will care. Fun to play with for sure.
Stephen G.
Great fitting, heavy knuckle with a surprise!
Brad W.
Badass knife, well made, beautiful.
Brian D.
What a unique knuckle duster The blade is extremely sharp and awesome protection when needed You won’t be disappointed!
Mike G.
Excellent Quality, fast shipping and great customer service. hard to beat
Travis F.
Great knife has a nice weight to it the only problem I’ve had was the a few times that I have opened the knife it has opened fully. But other then that I am happy
Mike S.
Really good self defense piece... hope I never have to use it that way.. but it is well more than adequate for that purpose...!
Austin K.
Ordered the new knuckle otf as soon as they released it and got it within a few days. Great action on this piece, she is pretty heavy but it feels good, it is not uncomfortably heavy
