Full information


A folding version of the Pentagon, the Pentagon Elite has all the benefits of its big brother as well as a bead blasted blade that reduces reflection. The stainless steel blade offers the instant choice between a serrated or beveled edge, giving you the best of both worlds for cutting virtually any material. Extremely lightweight, the Pentagon Elite features a glass-reinforced GRN handle with stainless steel liners that provides sensational feel and balance. Tested at over 1000 lbs. of force at the lock, the Arc-Lock is SOG’s strongest lock. It can be carried conveniently with its reversible low-carry pocket clip.



    The Arc-LockTM

    With its ambidexterity - and all the other attributes knife enthusiasts so relentlessly seek - the Arc-Lock might just be the perfect lock.

    Tested at over 1000 lbs. of force (measured at the lock), far surpassing conventional lock strength.

    Lightning-quick, one-handed opening and closing capability.

    Spring-action securely retains blade closed, keeping fingers safely clear while unlocking.

    Self-adjusting over time and easily cleaned for long-term optimal performance.



    VG-10 is well-known high-end Japanese steel and is considered premium. It contains vanadium which is known for its toughness. The steel is specially designed for high-quality blades used in cutlery. VG-10 can be sharpened to a fine edge that is very durable. It can maintain a hardness of Rc 60 without becoming brittle.

Customer Ratings & Reviews

Pentagon Elite II is rated 4.5 out of 5 by 14.
Rated 5 out of 5 by from Best Knife Ever!!! My EDC knife for over 10 yrs. Lost 1st and bought another. Smooth open/close. Holds a decent edge but expect to sharpen weekly to hold a shavin edge

Rated 5 out of 5 by from Great Knife I cannot say enough about this knife. I have owned it for about for probably 10 years. I use it pretty much every day either at work, at home, on the ballfield or at the fire station. If I had 1 complaint it is that I cannot keep it sharp.

Rated 5 out of 5 by from easy to operate This is my EDC knife that I have had for nearly 5 years. It is very easy to open and close and the blade really holds an edge. In fact I have never had to sharpen it yet, but I don't open letters or boxes and the like. This is my go to knife.

Rated 5 out of 5 by from The Best, & Unique ! As a senior citizen, I've had many knives ,through the years. It's lightweight, & I keep in within reach at all times,(24/7). With the 5" blade, & superior design,& construction, it's much more practical than carrying a sidearm everywhere I go. It's the best, & unique !

Rated 4 out of 5 by from Great Knife! I have owned this knife for about 8 years now and it has withstood everything I can throw at it. From everyday carry and small jobs, to dressing big game, it has been an incredible, durable tool through it all. It holds an edge well. I also like how the pocket clip can be configured for different carry styles. At first, I didn't like the non-assisted blade, but the action is so smooth, so the blade swings out with just a flick of the wrist. I own several SOG (and other brand) knives and this one is among my favorites.

Rated 5 out of 5 by from Best duty knife I have had this knife for over a year and it has performed well on duty. It carries easily in my vest and is sharp enough it makes easy work of seatbelts. Plenty of leverage thanks to its length. Best factory knife I own!
