BU0650BKSTP: 650 TOPS/Buck Nighthawk

Buck Knives

Outdoor - Survival & Tactical

Rugged, reliable and durable. A full-sized, fixed blade knife with dramatic, ergonomically designed non-slip grip handle. The blade seems heftier and the edge sharper than most Buck Knives - this is a great knife to use for a variety of tasks with a superior sheath and really great price.

Buck: "We knew we were creating an award worthy knife when we collaborated with TOPS Knives to create the 095 TOPS/Buck CSAR-T. The proof came when

Field and Stream

magazine named this innovative knife the "Best of the Best in 2010" in the Survival category. Continuing Buck's dedication to bringing those who serve and protect tools they can always count on, we are introducing several TOPS/Buck products. The uniting of these two Idaho knife manufacturers brings over 100 years of development and manufacturing knowledge along with unequaled field experience to every TOPS/Buck product created. If you, like most, were impressed with the 095 CSAR-T, you will be awed when you see and feel the fixed blade CSAR-T and other TOPS/Buck products."

Catastrophic failure
I loved this knife. I loved using it and I loved the steel and its capabilities, how easily it took an edge and how thick the spine is. Only downside is the hollowgrind, would prefer a normal flat grind. Until one day when I dropped the knife, which landed on a sharp metal bracket sticking out if the floor. The blade snapped in two right by the first of the two holes drilled through the blade. I was so surprised. Until that point it was the best, most sturdy and reliable knife I owned. Now it's completely useless, and I'm in the European Union so Buck's warranty does not apply. Surely this is a problem with my specific knife since I haven't found any other reviews saying the same thing. If you're in the US then I wouldn't hesitate buying it since it comes with a lifetime warranty

Look elsewhere
Buck is a nice knife company, but this shouldn't have their name on it. Because it's so abnormally heavy, it's not balanced correctly. It's very dull. The handle is cheap and grip is alright. Trust me, you'll want to return this once you buy it.
