The Hatsukokoro Kumokage Series offers high performance paired with the rustic good looks of a kurouchi blacksmiths finish. Made from Aogami also known as blue #2 wrapped in an iron cladding this knife will have will take a very sharp edge with excellent edge retention but if fully reactive so the proper care must be taken. These are handsome knives with performance to back up the good looks at a great price. 

*The Petty or Utility knife is a small knife used for smaller and more delicate tasks. They range in size from 120mm to 210mm and usually have a short blade height and thin blade. They can be used as a line knife or to prep various smaller items. Great for things like cutting fruit, herbs or even to portion and slice smaller proteins. In our opinion this is a top 3 knife everyone should have in their arsenal.*

    • Never use this knife to cut through frozen foods, bones or other hard items. 
    • After use be sure to wash using warm water, dish soap and a soft non-abrasive cloth or sponge. 
    • Dry knife immediately after washing to avoid corrosion.
    • If storing for an extended period of time use a knife oil like the one found here
    • For edge maintenance and sharpening use whetstones, strops, or a fine ceramic honing rod. Avoid oil stones, diamond stones and steel rods
    • Some high carbon knives will need to be wiped  dry periodically during use if cutting highly acidic foods to avoid corrosion.
