SOG Knives Bi-Polar Dual Blade Folder
29 October 2007

Every now and then I receive an item for review or evaluation in the tactical arena that just overwhelms me with its potential use in the recreational field. That’s what happened when I received a SOG Knives Bi-Polar TiNi dual blade folding knife. While the knife obviously has application for military and law enforcement professionals, the spectrum of use during off-duty time seems just as wide and varied to me. Let’s take a look at the knife, starting with the basic information and then examining some of the uses it can serve.
The knife is equipped with two blades and a glass breaker. The main cutting blade is 3" long and .120" wide. It's beefy enough to handle plenty of cutting chores without starting to pretend that it's Rambo's short sword. The second blade is a "SOG V" blade that is essentially two small razor blades set against each other at an angle. SOG obviously had public safety in mind when they designed this knife because the glass breaker is set into the end that would position it properly for use immediately before deploying the V-cut blade. Still, although primarily designed for public safety work, I can see a variety of field uses for this blade.
Let us not forget that, first and foremost in the field, we have to be able to support and/or rescue ourselves. When moving about in the "back country" it's not uncommon to find ourselves snagged on vines or snared by briars. The V-cut blade is perfect for a quick drag through whatever it is that has us tied down. If the "whatever it is" proves too much for the V-cut then the larger blade can be used to cut or hack (albeit small things).
Both blades have secure lock-back mechanisms and open using SOG's Assisted technology. That means that you just get them started and they'll flip open the rest of the way on their own. As a safety precaution, because of the assisted opening technology, SOG also designed and incorporated into the knife locking devices that prevent the blades from every opening unintentionally. This would really only be a problem if you had the knife in your pocket with other items that might catch and push the blade(s) open, but with the included SOG Nylon sheath there is virtually no way for either blade to open accidentally.
I know a gentleman who is an avid white-water rafter and this also seems in ideal knife for some of his needs. He's often asked for recommendations for a folding knife where he could open a blade - or get an exposed edge - to cut nylon or cords without endangering an air-inflated pontoon or hull if the knife was dropped. The V-cut blade on the Bi-Polar is perfect for his needs. The only thing he might need that SOG didn't include in the design is MAYBE a lanyard hole. I know how this particular white water fan likes to tie his equipment to his person.
While SOG's website has this particular knife (with the TiNi finish on the main blade) listed at $160, a quick Internet search revealed variations of the SOG Bi-Polar knife for as low as $99. That's a lot of capability in a small package. Versatility and safety are what it's all about when you're out in the wilds on your own. The Bi-Polar would make a good partner to have.
BE SAFE!
