We partnered with our friends at KITCHEN KNIVES ID to create our Kurouchi Tsuchime line of knives! All knives come with snap on plastic cover. These knives are a great value, you wont find very many high quality hand made knives at this price point. 

*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.
