After those who really depend on a rugged knife in the most demanding conditions welcomed the TOPS/Buck CSAR-T folder, it was inevitable there would be demand for a fixed-blade model. And now Buck has combined with their Idaho collaborator TOPS to create another high-performance tactical/survival knife, this time with a full-tang 4-1/2” fixed blade.
The highly functional modified Tanto blade reflects the years of TOPS expertise in meeting the specialized demands of professionals in law enforcement, military and other tactical fields. It is a hefty 0.18” thick, and Buck's heat treat process brings the 420HC stainless steel to an optimum hardness of Rc 58-60. It has a non-reflective, corrosion-resistant Zirblast® finish. A slot in the blade provides for oxygen bottle adjustments and wire bending.
With a contoured and grooved Rocky Mountain TreadTM G-10 handle, it provides the strength and secure grip needed in the harshest conditions. Adding to its versatility, the handle has an integrated hex driver, shaped at its end to serve as a dependable impact and prying tool.
Overall length is 10” and it weighs 8.8 ounces. The M.O.L.L.E. compatible nylon combat sheath has a front pocket. It all adds up to fulfilling the promise of its name: CSAR-T – Combat, Search and Rescue Tool. When survival is the only option, this knife will perform.
Made in America, and backed by Buck's Forever Warranty, the Model 690 has an MSRP of $150.
