This knife comes with a free sharpening ticket (valid for one year, one time only)
This knife is made of one of the highest quality steel. While we can assure you enjoy the excellent sharpness and edge retention, some users may experience chipping on the blade. In many cases it is caused by rough use of honing rods, which we do not recommend for this type of hard and razor-sharp thin blade.
Most of the chipping can be restored by whetstone sharpening, but this can be a little arduous. This sharpening ticket will save you from such an unfortunate case. Our professional sharpeners are here to take care of your first sharpening and maximise the performance and longevity of your knife.

About Kurouchi Knives
Kurouchi（黒打）is a type of knives that are only polished the edge line and left with black residue appearing after forging and quenching. The black part of every Kurouchi looks different to each other and shows a little imperfection in their looks. However, this rustic design is aesthetically pleasing to eyes and feels traditional craftsmanship.

Blue Super Steel （青鋼スーパー）is known for the highest sharpness and durability. Above the level of White Steel, Blue Steel contains smallest impurities as well as additional chrome and tungsten which makes the knives strong to wear and tear. With this mixture, Blue Steel is an ideal material for Japanese cutlery products.
It has a very narrow range of temperatures for hardening (Yakiire and quenching), and thus requires the blacksmith to be very skilled.

Kaz's Knife "No worries, Minor-Issue Warranty"
Having been used for a while, even good knives can get chipped and rusty as seen in the above video, but don't worry!
Most of the minor issues can be fixed by sharpening on a #400-#1000 whetstone. We have tutorial videos for you to learn how to use whetstone. However, it might seem a bit hard work to get it done by yourself.
Kaz's knife is offering "Minor-issue warranty" which covers small chips and rust on the knives you purchased from us. You can always contact us when you feel your knife became dull, chipped, rusty, etc. We fix those minor issues and send the sharpened knife back to you, mostly for free of charge! (depending on how much work is required, also you bear the postage for sending the knife to us)
(*) Please be advised, we do not warrant major issues caused by misuses such as dropped, cutting bones or frozen food, putting too much force into hard materials, etc.

Three merits to have good, quality kitchen knives
1. Better sharpness
Improving the cut quality of the kitchen knife, we can promise that "your cooking will be more delicious", "your cooking time will be reduced", and "cooking will be more fun".
2. It is easy to re-sharpen
