A folding knife designed for defense, the easy to carry SOG Pentagon XR features a 3.66” cryogenically heat-treated CTS XHP stainless steel, wide spear point blade and ultra-grip G10 handle. SOG’s XR Lock enables smooth ambidextrous single-handed opening in three different ways with distinguishably solid blade-lock once open with fixed-blade-like feel and confidence. The next level of enhanced pocket knife capability backed by Pentagon’s proven pedigree.
UPON LAYING HANDS ON THE NEW PENTAGON XR, THE FIRST THING FROM OUR MOUTH WAS, "DAMN". The ergos, lock up, heft and smooth pivot operation put the Pentagon XR solidly above the brands previous station in the knife world. SOG's new XR locking system is strong enough to hold a Toyota, and its spear point blade is wide, sturdy, and tipped with a slight back edge that makes delicate work possible. - Recoil Magazine, July 2020.
