Oyama Series

ZDP189 is a steel normally confined to the world of custom knifemaking. With a carbon content or around 3% it far exceeds high quality VG10 (~ 1% carbon) or R2/SPG2 (~ 1.4% carbon).

Sometimes it makes a guest appearance in a wa-handled Japanese knife with an elevated price but rarely does one get to taste ZDP at a non-stratospheric price

The Oyama from Hachido is a wolf in sheep’s clothing. For those that want only the best Japanese steels in a familiar western handle the Oyama does not disappoint. Lift up the bonnet to find a supersteel core of ZDP189 that is honed to an edge that will cut the toughest of mutton with ease. The steel is hardened to a sensible HRC of 63-64 (lower than the maximum HRC 67 for this steel) for ease of use and less brittleness than the majority ZDP knives.

• Impressive sharpness
• Elite durability
• Superior long lasting sharpness
• Exotic rare Japanese super steel
• Will handle a wide range of tasks with ease

Despite having a whopping 20% chromium content, the edge may form a grey patina with use. This is purely a function of the low chromium to carbon ratio. The patina can be easily removed with rust cleaner or a rust eraser.

Hachido Knives

Hachido – Eight Paths in Japanese, has a root of the Ancient Buddhist concept of the Noble Eightfold path. In terms of Hachido knives it refers to The Steel, The Quench, The Sharpening, The Polish, The Fit, The Finish, The Feel and The Cut. To be called a Hachido knife the knife must excel in these 8 paths.
