SOG Knives describes this item as follows:
The Bi-Polar is very capable. It's the first dual assisted knife with twin blades. Using patented SOG Assisted Technology™, each blade is propelled out once the operator has initiated the blade opening action. It might be the perfect rescue knife, whether used by law enforcement, emergency medical personal or in your garden releasing the grip of a tenacious vine. We think the Bi-Polar is the perfect combination of might and right with main blade, fully serrated secondary blade, and glass breaker. Dual blades, double lockbars and twin safeties all work to lock the blades closed or double lock the blades open. Expand your world with the Bi-Polar.

- Blade: 3" x 0.120"
- Steel: AUS 8
- Edge: Straight & Serrated

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!
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.
A very widely used EDC steel, AUS-8 can take a very nice edge while also maintaining moderate edge holding and corrosion resistance properties.
The lockback system has been used for many decades. It can usually be found on the knife spine and it provides a strong lockup that will wear well.
Durable, flexible, abrasion and mildew resistant, Nylon also is very strong
A solid, lightweight material that can be molded, textured or anodized to provide better grip under extreme conditions.
