SOG Specialty Knives Pentagon Elite II

The SOG Pentagon Elite has become a respected favorite among the military and law enforcement community as well as the general marketplace. SOG has also created a larger version of the popular Pentagon Elite I, the Pentagon Elite II, the company's first 5" folding blade! With an overall length of 10.75" the PEII is the monster truck of tactical folders. Both of these formidable blades make a serious statement as the first folding knives to debut Spencer Frazer's, amazing Arc-Lock. Together, the Pentagon Elites form a powerful tactical tag team.

The Arc-Lock sets a new standard in tactical engineering. It has all of the attributes knife designers have relentlessly searched for, but rarely find—(1) Strength: The Arc-Lock was independently lab tested at over 1000 lbs. of pressure without lock failure. (2) Speed: Spring-action provides fast and smooth one-handed opening. (3) Safety: Positive closing feature ensures that the blade securely stays within the handle when closed. (4) Ambidexterity: Blade can be comfortably accessed with either hand. (5) Durability: Arc-Lock is self-adjusting for long-term, optimal performance.

"For 14 years we have been developing and searching for a lock of this high caliber. Finally, the Arc-lock exceeds our expectations. I enjoy watching the Arc-Lock dance through its full-range of motion unlike any other mechanism on the market. This in-turn allows you to see 'full lock-up,' an additional safety feature."
—Premier Designer, Spencer Frazer.

The Pentagon Elite was created to fulfill the many requests for a folding version of the original SOG Pentagon and Mini Pentagon fixed blades. A frontline companion, the Pentagon Elites are impeccably balanced and come with an AUS 8, bead-blasted blade with partial serration to perform a wide range of cutting applications. This uniquely flat ground blade is surgically sharp and highlighted with SOG's "shark tooth" tip for reinforced point strength. An additional tactical advantage on the Elites is the inclusion of a reversible, low-reflective military style clip, which is securely mounted on a lightweight, tactical grip Zytel handle.

The Arc-Lock is basically a rotating cam that intersects the knife tang. Once engaged, the harder you try to force it closed, the more it wedges. Physics is a beautiful thing. This combined with ambidextrous one-handed opening and closing, a very strong blade retention in the closed position (important safety issue) that is easily overcome, and a completely unique action sets Arc-Lock apart. When showing this lock we always invite the customer to “watch the dance” of the lock button which travels back and forth in a type of lunar fast motion. Check it out. Also, did I mention that with it, knife opening is like lightening?! You can also unlock the blade (with a little practice) by holding back the button and flipping it closed in an instant. Easy come, easy go.

Independent testing by an outside laboratory of the Arc-Lock came back with outstanding results. The lock was tested with pressure applied 1/2” back from the tip on the spine of the knife and did not fail until 338 pounds of pressure was applied. That equals 1,183 pounds of pressure directly to the lock before it failed...a significant achievement.

The design of this lock is self-adjusting over time. As it wears, it becomes more secure with greater contact surface interfacing between lock and tang and the angle of interfacing becoming greater. Relative to fouling by debris, the open design allows the user to see directly into the guts to make sure that the lock has moved into the forward position. It also allows itself to be more easily cleaned and/or blown out.
