Buck Knives TOPS CSAR-T

The CSAR-T did well in every general utility cutting task—cutting, chopping, slicing, and whittling, it proved to be a very worthy tool.

In 2010 TOPS Knives and Buck Knives collaborated on a new design for a heavy-duty folding knife that was purpose-built for use by combat search and rescue personnel, and their CSAR-T tactical folder was released. Now they have teamed up once again to produce the new CSAR-T fixed blade, a larger knife designed for use in rough conditions.

All those familiar with TOPS Knives will immediately recognize the Rocky Mountain Tread handle scales, the strategically placed texture grooves on the upper and lower surfaces of the handle, and the dot-dash-dot pattern of the Morse “R” machined into the blade. The CSAR-T fixed blade is a full-sized knife with an overall length of 10-inches. It has a modified tanto blade that is 4.5 inches long, 1.25 inches wide, and made of 3/16-inch 420HC stainless steel. The blade features a compound-grind edge geometry, and sports Zirblast, ceramic bead blasted, matte finish to reduce reflectivity. The primary edge has a hollow grind for excellent cutting and slicing capability even with a thicker blade, and the tip has a stronger saber grind for added strength and durability. The handle is 5.5 inches long, sports heavily textured G-10 handle scales and has a stout 0.5-inch tang extension that multitasks as a glass/skull breaker, and as a striking point for using the knife in chisel fashion. The lanyard hole also pulls double duty as an attachment point for a driver bit.

In rescue operations, knives can and will be called on to perform unorthodox tasks. A strong, durable tip really comes in handy on those occasions.

Field Sharp
I have had the pleasure of handling quite a few Buck knives over the years, and I’ve used several of them out in the field, so I am used to them being sharp out of the sheath. The hollow-ground edge of the CSAR-T I received for testing brings a whole new dimension to this usual sharpness, and hardened to RC 60-61, it holds that edge well. After feeling the keenness of the edge I couldn’t wait to put it through one of my personal favorite tests.

A. Even weighing in at just 8.8-ounces, and a blade length of only 4.5 inches, the CSAR-T can still do well at light chopping when needed. The wedge-shaped handle allows for a secure, two-finger, rearward grip that lets the user bring some extra mass to bear in each blow, while the hollow-ground blade bites fairly deeply.
