That was kind of surprising to me, the rock chopping was kind of extreme, but to prove a point. With a solid carbon steel, with a quality heat treatment, you should not be able to get a blade to shatter in pieces. I was impressed with the durability of the Howling Rat after that and I don't impress very easily.
Of course the other aspect is that this blade cuts very well, it is *NOT* a thickly ground tactical knife. The toughness is achieved not by simply laying on more steel, but through a very high performance steel due to the very high standards set for heat treatment and quality control at Swamp Rat.
