Product Description

Product Description

Flick the Flash II – with either hand – and get 3.5” of AUS-8 stainless steel sliding from the handle so fast it makes the blade blur. Believe it. That’s thanks to SOG Assisted Technology (S.A.T.), a system of opposing high-tension coils that propels the blade open instantly once you give it a flick.

From the Manufacturer

The Flash II 3.5" Knife has got to be one of the coolest knives we’ve ever seen. Forget its wicked-quick blade access, that it handles like a race car on rails, or that it locks up like Alcatraz. It just looks and feels extraordinary. The Flash family of knives feature SOG Assisted Technology (S.A.T.), which employs a powerful piston lock that is easily released with a sliding button. We also had the foresight to incorporate an additional safety lock that gives added security when the blade is closed. Note that when the safety shows red, you are ready to go!

Customers are satisfied with the sharpness of the knife. They mention that the blade is definitely sharp, and can be sharpened without worrying.

Customers like the ease of opening the knife. For example, they mention it's easy to open with a touch of the thumb, it retains edge and the spring assisted opening works great. That said, some say the mechanism is great and it allows for quick deployment.

TEN YEAR REVIEW
4 Stars
TEN YEAR REVIEW
Pictures were taken today. I ordered this knife from Amazon on July 22, 2011 and have carried it almost every day since. That's a pretty good endorsement in and of itself, as I am a power user. I can't begin to tell you how many miles of backcountry hiking, paddling, and camping this knife has seen in those 10 years. It's processed tons of food, cleaned fish, cut thousands of pieces of paracord, whittled hot dog sticks, feathersticks, you name it. Plus everyday use like breaking down cardboard boxes, cutting twine, wire insulation, gas lines, etc. Here are my thoughts after 10 years of heavy use:The overall durability of this knife is top notch. The AUS-8 Satin has held up wonderfully and it takes and retains an edge like the day it was made. There are some scratches on the blade, and even a little patina...just evidence of a well used knife. Deployment is still wonderfully fast, I've never once had the blade slip out of the locked open position, and the blade release still works like new. The handle texture has held up great and the pocket clip still maintains its original grip. That pocket clip was one of the main reasons I bought this knife in the first place...it's oriented correctly and secures the knife deep in the pocket. I can honestly say the longevity of this knife has far exceeded my expectations. I'm almost 50 years old, I've owned/lost/broke countless pocket knives, and am simply amazed at how this one has held up.I do have a couple minor gripes: This knife does have the SOG-typical blade play, both horizontal and vertical, that I don't much care for...but again, 10 years of heavy use and it hasn't caused an issue in functionality, so I can't really complain. But it is there. And the lock is completely pointless. As you can see from the pic, I have a small piece of electrical tape jammed in the lock to keep it in the unlocked position. That same piece of tape has been there for all 10 years and the blade has never accidentally opened in my pocket, even when scrambling through and low crawling under thick brush. If there was a lock-less version at a reduced price point I would buy it in a heartbeat.Just as side notes, I've only ever used this knife as a knife...it's never been a screwdriver or hammer or prybar. I also have small-medium size hands and the fit and feel are fantastic.That's it. It's not perfect, but it's pretty darned close. If you treat this knife right, it will give you many years of reliable service, mine is proof.
