Another addition to the ever popular Hatsukokoro Hayabusa(隼,Peregrine Falcon) line, featuring the edge retnetion king: Hitachi ZDP-189 powdered steel. With over 3% of carbon content and up HRC 67, the Hayabusa ZDP-189 line is designed for those seeking the ultimate long lasting edge.
Previously this steel was almost found exclusively on Sukenari knives, and they usually comes with a rather big price tag. That situations may just change with the introduction of the Hayabuse ZDP-189 serie, with a fit and finish that is arguably on par with the Sukenari, these hyper steel blades comes in with a price that is close to some SG2 knives. Hayabusa also offers a very thin grind, as a result it is a lightweight laser, with a thin flexible blade.
For those who are fascinated by the knives with cutting edge(pun intended) powder metallurgy and extreme numbers, this undoubtedly will be the easiest way to get your hands on the ZDP-189 steel.
