About SOG Pentagon

The SOG Pentagon fixed blade was originally designed as a back-up knife for law enforcement and military personnel, but the Pentagon series is now popular with outdoor knife enthusiasts as well. The Pentagon offers the instant choice between a serrated or beveled edge for cutting options. The twin thumb notches enable accurate blade orientation and downward control. The checkered handles are flared to provide confident gripping as well as superior feel and balance. The Pentagon comes with a tactical nylon sheath.

Break in period!

Chris B.

The break in period on this knife took about a week. The XR lock was the only way I could get it open. The flipper and the thumb stud would just not budge. I considered sending it back but then, slowly but surely it started opening smoothly. I was tempted to remove a star for the frustration period I had with it but, the enjoyment I get now just from the sound of it opening makes read more up for it. Do it slowly with the XR lock and you'll see what I mean... sounds like a hinge on a medieval suit of armor or something.

The Pentagon is my designated self defense knife so I also carry a SOG XR Ultra or a Bugout for any light duty cutting tasks. If you need a self defense blade that will serve equally well in an outdoors/utility role, there are better options, such as the SOG Trident AT. I have that one too. It's just slightly too thick for me to carry comfortably around the city in my jeans pocket.

My new favorite knife

It will work as an edc but this thing is just straight tactical. Excellent duty knife if that's what you're looking for. Ergos are good and the XR lock has improved considerably over the years. Truly a gem of a knife

Another great XR...

As I would expect from SOG this is another quality knife. I love the new XR line and also this dagger blade version. Smooth action, great lockup, perfectly centered blade with no play. It doesn't hurt that it just looks great too. The only reason I took 1 star is because the very straight handle doesn't fit well comfortably / ergonomically in my hand. Other than that, I would totally read more recommend this knife. I have a couple more XR models on their way to me and I can't wait to get my hands on those too!
