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.
