Yoshida Hamono Blue2 Kurouchi – Petty 150mm


Yoshida Hamono is a Family owned company with a rich history of knife and sword manufacturing. They manufacture knives at their workshop in Saga Prefecture, Japan.

The Yoshida Blue 2 range comes at a sharp price for a hand-forged knife. They are nice and thin behind the edge and are very well balanced in hand.

The Yoshida Blue 2 knives have a core steel of  Blue 2 Carbon steel cladded in soft iron. Both the core and the iron cladding are reactive Carbon steel. This knife patinas nicely, but extra care is required when using the knife. We recommend that the blade be wiped down regularly during use and washed and dried properly after use. We recommend getting a rust eraser for maintenance.

Using a good cutting technique is very important. Make sure your cutting motion is straight up and down with no lateral movement when hitting the cutting board.



Petty (Paring/Utility) Knife (ぺティ – pronounced: Petti Naifu). It is said to be derived from French ‘petit’ meaning small or little. The Petty Knife is seen as a small Gyuto making it purposeful for any use in the kitchen.

The petty knife is perfect for smaller working surfaces, cutting smaller sized produce if for users with smaller hands. Its comparison to the Gyuto makes it the ultimate small-sized all-rounder and professional cooks prefer it for its compact size and versatility. It can be used to peel, slice, dice, mince and trim a variety of smaller fruits, vegetables, herbs, garnishes and proteins. It is perfect for light butcher work and delicate tasks such as making precision cuts. The blade profile is well suited for thrust-cutting while the belly allows for rock-cutting.

The Petty knife is generally larger than a Western petty knife. Similar to the Gytuo the Petty knife’s heel to belly is quite flat with a rounded profile to the tip. The sharp, double-bevel edge makes this knife ambidextrous and is the perfect companion in a small kitchen with limited workspace or for users with smaller hands.

Care Instructions

  • Wash and dry the blade by hand immediately after use. Dishwashers are very bad for all knives.
  • Use a soft cloth to wash the blade. Avoid abrasive dish scrubbers and powders as these can damage the finish of your beautiful knife.
  • Do not cut through bones. You can certainly cut along/beside bones, but do not cut into bones. This can, at worst, chip the blade.
  • Never use this knife to cut frozen food.
  • Never twist or cleave the blade.
  • Always use a wooden or plastic cutting board. Never cut on bamboo, glass, marble, slate, a plate, china, marble, arborite or anything harder than steel.
  • Store knives in a way that the blades will not knock into each other.
  • Never transport knives unprotected.
