Brand new directly from Protech Knives, Made in the USA.

Blade: CPM S35VN delivers a highly corrosion resistant and durable blade that has very good edge retention. The saber grind delivers good strength while the long top swedge provides a fine point for piercing and detail work. Our exclusive Acid Washed finish, acid washed and tumbled, is non-reflective hides wear from use while lending a rugged look. The blade deploys via a simple, robust button operated coil spring which delivers fast deployment when the seconds count. A slide safety offers added safety when carrying.

Handle: 6061-T6 Anodized aluminum makes the Tactical Response both tough and lightweight. This custom "Flag" variant has a Vintage Flag pattern anodization done by Peter Kellett. Milled finger grooves provide a comfortable and secure grip in the hand with subtle jimping for indexing. A hardened 410 steel backspacer contains a generous lanyard hole and protrudes from the pommel end of the handle for use as an impact tool. The Tactical Response TR-5 carries via blasted, matte gray, stainless steel deep carry pocket clip set up for right hand, tip-up only carry.

CPM S35VN: was designed to offer improved toughness over CPM S30V. It is also easier to machine and polish than CPM S30V. The inclusion of Niobium allows for the formation of niobium carbides along with vanadium and chromium carbides. Substituting niobium carbides for some of the vanadium carbides 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.
