A note on cladded blades: Cladding sandwiches the hardened steel core (i.e. the cutting edge). Cladding gives the blade durability - in particular resistant too breakage, and is more easily abraded for the purposes of profiling and sharpening. Cladding is referred to as 'Soft', which simply means it is less hard that the core steel.>

{Information}Care Instructions
Wash the knife by hand using a gentle dishwashing liquid. Always dry immediately after washing with a soft cloth. Do not let the knife drip dry. Also do not wash your knife in a dishwasher, as it encourages the blade to rust and the wooden handle to dry out and crack over time.
The knife is made of Japanese high carbon steel. High carbon steel blades must be treated to avoid rusting. Japanese traditionally use Camellia (Tsubaki) Oil to treat high carbon steel tools. Ensure the blade is clean and dry before applying Camellia Oil. Simply wipe the blade with a clean cloth impregnated with Camellia Oil. Re-apply regularly.
If rust does appear on the blade use a rust remover to remove it
It's natural for the metal blade to patina over time. The metal patina results from coming in contact with food ingredients.
The wooden handles also require care. Depending on use, we recommend oiling the handle every 3-12 months (depending on use) with boiled linseed or tung oil.
Store your knife in a saya (our recommendation), the original box, a knife block or a mounted knife magnet bar/strip.
The blade is made from harden steel. Harden steel produces a finer edge, and has excellent edge retention. However, a harden steel edge can easily be damaged if not used in the manner outlined in the Description. Do not cut hard ingredients (e.g. frozen food, bones, hard rind on parmesan cheese, woody rosemary stalks, hard pumpkins, coconuts etc) or non-ingredients. Do not drop your knife. Only cut ingredients on a wooden chopping board.
The knife should only be sharpened using a whetstone. We highly recommend that the edge be stropped, with a leather strop, after sharpening. Do not use pull through sharpeners, regular or diamond honing steels or mechanical sharpening machines.
A Ko-Bunka is primarily used for chopping, dicing and mincing small fruits and vegetables. In essence a Ko-Bunka is a different style of Santoku. The blade of this knife is hand forged by blacksmiths and the handles are made of wood. As a result, there will be minor variations in blade length, appearance of the blade finish, wood grain and colour. The product images should be treated as a close approximation of what will be received.
