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.

Look for the new Cryogenic Heat Treated logo on selected SOG Knives that have received this process.

S.A.T. coil spring as seen in the Blink.

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).

We warn you... this blade action is addictive! Play with it once, and you'll be opening it again and again!
