This Pentagon XR has a black G-10 handle and a black finished XHP blade.

The SOG Pentagon XR is a full-size tactical knife that is perfect for a pocket of a soldier, police officer, or responsible citizen. This knife has a dagger grind, with the top being mostly unsharpened. The quarter inch nearest the tip on the dull side is sharpened, making this knife pierce deeply and easily. The handle is made of coarsely textured G-10. The blade opens with either the thumb studs or flipper tab, and locks up with the XR lock.

Break in period!
Chris B. on Jan 6, 2022

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 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.
