Schrade Viper OTF Assisted Knife Black (3.375" Black Serr) SCHOTF8BS

Schrade's Viper OTF looks like a design from the future. The double-edged partially serrated spear point blade is made of AUS-8 high carbon stainless steel with a black finish. The futuristic handle is crafted from black aluminum so it's lightweight and easy to manage. To open the blade, switch off the safety lock and press the sliding release forward. The knife opens fast and smoothly, and the lock up is tight. To close the blade, push the small blade release button forward, the slide the blade back with the bottom actuator until it locks into place. The pommel of this knife features a small glass breaker tip and a removable, tip-down carry pocket clip.

Customer Reviews

Excellent OTF for the $$$$
Christopher K. on Jan 18, 2017

I bought one of these and have had it for two months. It ejects the knife auto but retracts manually. The quality for the money is top notch. it snaps out strongly. There is pretty much zero play on the blade. I have some otf knives that cost 4 to 10 plus times the price and have more play. The material of the knife are well made too as well as the knives being very sharp. The safety button works well and of coarse when shooting it it has the safety feature like most to not fire the whole knife out. Like it so much will probably get another one. Get one you shall not be disappointed!!!!!

Awesome knife
andrew p. on Sep 14, 2016

This is an awesome knife. I just got mine in the mail today like 4 days after i ordered it which is cool also, but the knife is better quality than i expected doesn't look cheap at all and no blade play at all i have many other more expensive knives with more blade play and the AUS-8 blade is super sharp right out of the box. Definitely recommend this knife if your interested in it.

Shcrade hit it out of the park with this one.
Joshua M. on Mar 5, 2016

I've been eyeing this knife for a while and finally ordered one. NOT disappointed. This is such a solid knife, especially considering the price. The firing, safety, and lock release mechanisms are all perfect. The blade fires very powerfully — for example with a Lightning or Titan, you can fire it into a sheet of paper and barely puncture the paper, whereas this knife would punch right through cardboard and keep going for an inch or so. Also, the steel being AUS-8, you can tell the second you touch this knife that it has a *much* better blade than other knives in the Schrade OTF category (the ones with the release button on the bottom are crappy 4000-series stainless steel not fit for letter openers). Another thing I liked about this knife is the edge it came with — very sharp. The handle texturing design seems random in places but the knife is very grippy overall and comfortable to hold in the hand in any grip configuration. Also, the glass breaker is awesome — I don't know if it's steel or tungsten but I do know I had no trouble etching glass with it. It etched the glass even better than the one on my CRKT M1614LE which I know is tungsten. I also really love the fact that this knife is technically legal but still looks and operates like a single action front-firing automatic. And this review would not be complete if I didn't mention the fact that after personally handling this knife and handling the Benchmade Infidel, I can tell you that the $400 Infidel has MORE blade play than this $40 Schrade. Folks, for $40 this is a ridiculously solid knife and it gives me new respect for Schrade. If you can't find/afford a real Dalton Cupid (the one the Joker used in The Dark Knight) and you can't bring yourself to get some crappy no-name Cupid clone cause they are suck-a-riffic, then this knife is the answer.

Stiff action, needed oil
Albert K. on May 13, 2020

Blade would not lock out consistently. I used it, after manually pulling the blade out and getting it locked, and oiled it. The switches are very stiff and difficult to use for an old man. Feels a bit like a toy. Oil helped but may need to return it if it doesn’t smooth out.

That didn’t last long.
Tim B. on Apr 27, 2021

I loved this knife when I first got it. It’s a bit large, boxy and the button layout not very intuitive. Hey it’s a cheaper knife I get it, but after two months the blade when under pressure would retract. That did it for me! If you are looking at this you get what you pay for. If you want something a bit more.... then up your budget.
