I think of the term "hard use" as asking a knife to perform well and long within the design limitations of that knife. Hard use is set by excellent design, high-quality materials and superb construction. Spydercos excel at hard use.
Knives that stand up to abuse are defined partly by the above considerations, but also by heavy geometry. Make a knife thick enough, obtuse enough and it will hand virtually any abuse. But you lose performance. A lot of performance. Spydercos are not designed or manufactured for abuse. They are made for high performance cutting and will stand up to hard use within the designed intent of the knife.
