Just received this Tops/ Buck CSAR-T 3 days ago. Initial impression is good, knife is extremely overbuilt and decent materials are used, ATS-34 steel, g-10 scales.....Blade is a uniquely designed modified Tanto and is pretty thick at 3/16. Lock is a liner but its pretty thick and seems like it will hold, I'm not a big liner lock fan) however, this knife appears to be quite substantially built. Contrasting it to previous Buck collaborations, like the strider SBMF Buck, this liner is quite an improvement. Additional observations include a decent hollow grind, beginning about mid blade, ambidextrous thumb-stud and reversible tip up pocket clip. The American made CSAR-T comes with a very usable nylon sheath with multiple carry options. Buck and Tops websites talk about the optional 1/4 tool kit available for the knife. On one side of the lanyard hole the liner has a hex socket that accepts most 1/4 bits, as of yet I have not tested this feature. I have, however, thrashed the CSAR-T pretty hard and so far have been quite impressed for an knife at the under $100.00 price point. Blade shape is very well suited for all utility tasks and still maintains some tactical ability ,at least in my opinion. Jimping is good and the ats 34 blade treated with the Paul Bos proprietary heat treat appears to hold an edge very well. I have been collecting for over twenty years and own many knives including 50 or 60 Bucks. However, the CSAR-T is my first experience with Tops , so far so good. Despite it's heavy weight (almost 9 ounces ) and its chubby width, I plan to edc this for a while I'm sure I'll have fun testing this knife for the next couple of weeks at work & at home. If any body else has any thoughts on this knife I'd like to hear it................Fox
