SOG® Flash II Straight Edge Folding Knife. Perhaps one of the coolest knives you'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.

The Flash II comes standard with glass-reinforced Zytel™ handle and straight edge, satin finish blade. All Flash knives come standard with SOG's patent pending, reversible bayonet mounted clip that ensures the lowest, most discreet carry possible. They also had the foresight to incorporate an additional safety lock that gives added security when the blade is closed.

More on S.A.T.: SOG Assisted Technology works through the balance of opposing high-tension coil springs. As one opens the blade the force to propel the knife open becomes greater than the closing force and the blade will open on its own. The end result propels the blade out once the operator has initiated the one-handed opening action. S.A.T. works so well that right-handers can use their left hand equally well to open a folding knife (of course this works oppositely for lefties).
  • Blade length: 3.5" x .125"
  • Overall length: 8"
  • Weight: 3.1 oz.
  • Edge: Straight
  • Steel: AUS 8
  • HRC: 57-58
  • Handle: Zytel
  • Finish: Satin
  • Assembled in the USA.

SOG® Trident Digi Camo Folder Knife. Deploys in a blink of an eye!

The Trident uses SOG's well-proven means of delivering a knife blade to the open position with S.A.T. (SOG Assisted Technology™). Now using their patent pending Arc-Actuator™, the Trident locks stronger and releases easier. There is also a built-in safety to lock the blade closed.

When it shows red, you are ready to go. What also makes the Trident so unique is the patent pending Groove™ in the handle, which allows the operator to cut paracord, fishing line, etc. without having to open the blade. The handle also includes a Digi-Grip™ variable pattern for coarser grip in areas that require it. Our bayonet style clip is easily switched for right / left hand carry or removed for pouch storage.

Cryogenic Heat Treatment

SOG's unique cryogenic heat treatment process increases the toughness and wear resistance of our blades. Taking the knife slowly down in temperature to less than -300°F and then back to room temperature.

This stress relieves the material on an atomic level and increases overall strength as well as edge retention. Knife edges stay sharp longer with significantly less micro-fracturing and edge-chipping. Its this dedication to making your knife SOG sharp that sets us apart from the rest.

SOG Assisted Technology

SOG Assisted Technology works through the balance of opposing high-tension coil springs. As one opens the blade the force to propel the knife open becomes greater than the closing force and the blade will open on its own.

The end result propels the blade out once the operator has initiated the one-handed opening action. S.A.T. works so well that right-handers can use their left hand equally well to open a folding knife (of course this works oppositely for lefties).

SOG® Aegis Tanto Serrated Blade Folding Knife. Flash-action, one-handed operation!

Aegis (ee-jis), which in Greek means shield or protection, is also the code name for the world's premier integrated air defense system and the sea-based element of the United States Ballistic Missile Defense System. And this beauty is fully integrated with top end systems.

Start to open the knife, and let Aegis finish the action with a bang, using one of the surest assisted technologies (S.A.T.) out there! SOG's trademark bayonet reversible clip, built in safety with red / ready to go, checkered DigiGrip™ handles, and tacky rubber inserts all contribute to make Aegis a platform for today's changing world. Cover your back with Aegis outdoor or tactical blades.

More on S.A.T.: SOG Assisted Technology works through the balance of opposing high-tension coil springs. As one opens the blade the force to propel the knife open becomes greater than the closing force and the blade will open on its own. The end result propels the blade out once the operator has initiated the one-handed opening action.
