This blade design is excellent for all-around utility. Short enough to easily control the point, the A.T.A.K . is also long enough for very effective chopping.The blade steel is Starret...t 496-01 high carbon tool steel. Selectively tempered, the A.T.A.K . has a Rockwell C-scale hardness of 62 at the edge (as hard as a file), and HRC 50-54 throughout the spine and hidden full tang. This provides superior edge-holding ability with exceptional durability for prying and chopping. Each blade is hard chromed providing excellent corrosion inhibition. The ergonomic grip indexes the blade in the user's hand, thus letting the user know how the blade is presented, even in the dark.
