SOG Pentagon FX Covert Professional Fixed Blade Knife for Tactical Needs | Double-Edge CYRO S35VN Full-Tang Steel Blade

This is an excellent dagger and sheath design. I suspect this will be the swan song for SOG daggers, as long as GSM owns SOG. Fortunately, the Pentagon FX and FX Covert models were designed prior to GSM, and I'm glad I picked one up, since I missed out on the original Seki Pentagon's in SOG's heyday.The pentagon covert feels great in the hand with jimping in all the right places for a secure saber or icepick grip. The handle is small and not really intended for a hammer grip. The hilt is very minimal and slightly rounded, just enough to ramp your thumb against and hold your index finger secure, without being too wide or squared to catch on clothing or gear. Almost as smooth as a hiltless design. When held in a saber grip the jimping on the pommel also locks securely into the bone of your palm for thrusting motions. The same jimping on the pommel makes a secure backstop for your thumb in the ice pick grip.The sheath is equally well thought out with death grip retention and has several carry options; the pocket clip works well and holds securely to whatever you attach it to, the clip can also be removed and re-attached across the lashing holes near the hilt for scout style. You can also remove the clip for a slimmer sheath and use the lash holes with paracord to secure to your boot, ankle or use as a neck knife. You can even use Velcro tape on the smooth back of the sheath (clip removed) and attach directly to your plate carrier or any other gear with Velcro.One reviewer mentioned popping out the tabs on the inside of the sheath... DO NOT DO THIS. Those tabs pressure fit over the ends of the hilt and hold the dagger securely. Sheathing the dagger requires some force and produces an audible click when those tabs lock in place over the hilt. I suspect people are not doing this properly, hence the bad reviews regarding the sheath retention. I EDC the pentagon attached to the shoulder strap of my maxpedition sitka pack, pommel down, utilizing the stock UMS belt clip with no retention issues at all.Lastly, the only minor con that I can find is that the edges are not very sharp out of the box, as pointed out by other reviewers. The edge is serviceable and can be improved with honing, however, slicing tasks are not for dagger style blades. The design utilizes maximum tip strength for penetration tasks, and a little edge sharpness is sacrificed due to blade geometry. Out of the box, the point is sharp and well-formed for its intended use.

I love this knife, not to big not to small has good weight to it. Would recommend it for anyone thinking about getting it.

Smaller than expected and barely able to grip. Blade is nice but the sheath is absolute trash. $170 knife you should get a sheath that actually holds the knife in. Just turning the sheath upside down the knife would slide right out. Couldn't tighten or anything. Shows that SOG is still a garbage brand.

The blade is a bit smaller than expected but still fits a large hand okay. Very sharp on both edges.The small sheath thet comes with it is horribly loose. I will have to find something else thst SOG may have or get a custom sheath made.EDIT: There are 2 little tab just inside the sheath on either side. Using a small screwdriver, I popped those two little nubs out and the knife now fits nice and snug. My void the warranty on the sheath but at least its a snug fit now.

A decent knife for EDC, however, the sheath is a piece of cr@ppp. Even as a boot knife, it sits too high. Worst of all, after withdrawing the knife from the sheath a few times, I found that the the knife won't stay securely locked into the sheath any longer. No matter if you boot carry or waist carry, there's a high likelihood the thing will loosen and potentially fall out. Look elsewhere for this kind of money.

Arrived blunt. Almost impossible to get a good edge on the blade by multiple attempts and different methods of sharpening. The UMS advertised by SOG does not seem to exist and the clip it comes with is trash. SOG doesn’t reply to messages or emails with customer questions or concerns… Garbage product.
