SOG Pentagon XR Lock Knife OD Green G-10 (3.5" Black)

This Pentagon XR has an OD Green 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.

My new favorite knife
Kyle V. on Aug 1, 2021

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

SOG Pentagon
Stan W. on Aug 15, 2020

My first dagger blade. WOW! Very smooth action. Took a little sharpening--not much. razor sharp. Very good FUN knife. PW

Highly Recommended and Lefty friendly
Thomas E. on Nov 20, 2022

This is one of my favorite knives. The action on the XR lock is better than most of my Benchmades, plus it has a flipper! I really like the design and features. The build quality feels really solid and the XHP steel is holding up well. My only nit picks would be that the pseudo edge on the spine makes it uncomfortable to place your thumb on the back of the blade and I have had threads from my pocket liner end up caught under the screw for the pocket clip. I have also noticed that both of my XR lock knives have a tiny bit of blade rock in the closed position, but not enough to bother me or effect the functionality of the knife. Cheers, Thomas

Another great XR...
Todd D. on Sep 4, 2020

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 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!
