SOG Assisted Technology for Speed and Safety Fast, safe, one-handed opening makes SOG Flash Series knives incredibly easy to handle in a wide variety of situations. Once you start opening the knife, SOG's Patented SOG Assisted Technology, or S.A.T., takes over. Through the balance of opposing high-tension coil springs in the knife, the force to propel the knife open becomes greater than the closing force, and the blade will open on its own. This unique feature means that if you are using your dominant hand on another task, you can just as easily open the FSA-98 with your other hand.
For security and peace of mind, S.A.T. was developed in conjunction with a superior locking system. The unique design of S.A.T. knives allows them to use locking mechanisms that are stronger, more reliable, and easier to access ambidextrously than conventional liner locks.
For Flash Series knives, this means the blade is held in place with a reliable piston lock that can be released quickly with a sliding button. An additional safety lock offers extra security when the blade is closed. For easy reference, the lock switch shows red when the knife is ready to open.
Cryogenic Heat Treatment for Sharp, Dependable Blades Of course the workhorse of any knife is the cutting surface, and FSA-98 offers a full, 3.5-inch, half-serrated blade with an elegant satin finish.
SOG's proprietary Cryogenic Heat Treatment process ensures that this blade will stay sharp over the long haul. This intensive process takes more than 48 hours and involves slowly bringing the blade's temperature down to less than -300 degrees Fahrenheit, then bringing it slowly back to room temperature. The stress created through this process relieves the material on an atomic level and increases overall strength and edge retention.
Elegant, Ergonomic Design for Ease of Use Even if your blade is sharp, it's hard to make the cuts you want if a knife does not sit comfortably in your hand. That's why the handle on this knife features a unique, ergonomic contour. Crafted from tough, glass-reinforced Zytel, the handle helps ensure that your knife is both durable and well-balanced. And it is lightly textured to prevent slippage.
At just 3.1 ounces, this folding knife is lightweight and easy to carry. A reversible, bayonet-mounted clip extends from the back of the handle, allowing the knife to sit low in your pocket for the most discreet carry possible.
This knife is backed by a lifetime warranty that protects against defects in workmanship and materials.

Customer Reviews & CommentsThere are things about this knife I don't like, but then I find myself carrying it more often than any other knife I own. Here's what I like: 1. Assisted opening. I own several, and I don't think I'd buy a regular opening knife again. 2. The clip is superior. It's strong (one reviewer commented about lateral pressure damaging it...why on earth would you do that?). Best of all, only the clip shows in your pocket, not part of the top of the knife as with almost all others. 3. It's incredibly sharp. I can shave hair off my arm with it with no problem. 4. It's incredibly light weight for the size (I have the Zytel handle) 5. It's very resonably priced. And...what I don't like 1. The steel is not as good as I'd like. It's "good" quality steel, but not great. Plus it's a straight flat grind, which is asthetically boring. 2. The blade thickness is not what I expected. I haven't tried anything extreme with it, so it's not been an issue. 3. Yes, the safety will very occasionally latch in your pocket. However, you have to be insane to get into a knife fight...nobody wins. Using a knife for defense is nuts. When I was a deputy, I saw real-world results...dear God! Get a concealed gun permit if you're worried about self defense. So...I give it 4 stars. I have a Kershaw Blur that I like better except for the clip, which leaves about 1/2" of the handle exposed. I don't know why they would design it that way. When I carry it, I just carry it in my pocket without clipping. If you want a quality, inexpensive utility knife, this is it.
