Beautiful KATSU ZK02 knife. Rockstead style, traditional Japanese folder style. 17 damascus layer w/ ZDP-189 super steel with convex mirror polish grind. These knives are insanely sharp. These are amazing knives for the price, almost Chris Reeve and Rockstead quality for a fraction of the price. This one has been barely used, only cut newspaper with it. Carried for a few days, so it has few scuffs on the flat part of the clip (see photos). The entire handle, backspacer and clip on the ZK02 model are battleworn / stonewashed so they have already a worn in character, therefore these scuffs and any future scuffs will blend in very well. Otherwise no other major imperfections that I can see. Frame lock locks in well, no rock lock or blade play, easy to open w/ the flipper tab, aligns perfectly when closed, drops shut smoothly when closing. Knife is in perfect working order as it was when it came from factory. The little etching/marks on the outer layers of the blade (in pics) are normal and come from factory like this. Please see below for all information on these knives from KATSU. Heat treatment certification card. 17 layers ZDP-189 Super Steel. ZDP-189 is a Japanese Super High-end Stainless Steel.
