Based on the original SOG Pentagon dagger, the Pentagon OTF delivers a top slide, out-the-front automatic platform with a premium upgrade in materials while retaining the popular dagger design that has made this the choice of military and uniformed professionals the world over. This version comes with a Black TiNi coated CPM-S35VN blade and a Flat Dark Earth anodized 6061-T6 aluminum handle.

Brand new, direct from SOG.

Blade: A classic, symmetrical double edge dagger profile is delivered in black titanium nitride coated CRYO S35VN for balanced performance, good corrosion resistance and a discreetly non-reflective finish. A +3.5 inch blade operates fast and smooth via double action automatic mechanism. Press forward to deploy and back to retract, its simple and reliable and fully ambidextrous thanks to the top slide location. Dual fullers add aesthetic appeal while the dual cutting edges and fine point make this an effective combat tool.

Handle: Tough and lightweight 6061-T6 aluminum handle construction is designed for comfort and traction in the hand with strategic jimping and dual guards for safety. The symmetrical design allows the knife to be used in any grip or blade orientation. The internal automatic locking mechanism insures safety in both use and carry.

Carries via a tip-down only, removable stainless steel pocket clip .

CPM S35VN: was designed to offer improved toughness over CPM S30V. It is also easier to machine and polish than CPM S30V and the adjusted chemistry makes CPM S35VN about 15-20% tougher than CPM S30V without any loss of wear resistance. CPM S35VN’s improved toughness gives it better resistance to edge chipping.
