Why You'll Like It

Aogami Super Core Steel

At the heart of the blade is Aogami Super (Blue Super) Carbon Steel, one of Japan's most respected high-performance steels.

It offers:

• Exceptional edge retention
• Extremely fine sharpness
• Outstanding cutting feel
• Easy sharpening for experienced users
• Long-lasting performance

For cooks who prioritise cutting performance, few steels are more rewarding.

Traditional Tsuchime Finish

The hammered tsuchime finish is more than decorative. It helps reduce food sticking while giving every knife a handcrafted appearance that reflects traditional Japanese craftsmanship.

Precision in a Compact Size

The 150mm petty is one of the most versatile knives in any kitchen.

Ideal for:

• Garlic and herbs
• Shallots and onions
• Citrus and small fruits
• Trimming proteins
• Fine slicing
• Detailed tip work

Lightweight, agile, and incredibly easy to control, it's often the knife chefs reach for most.

Traditional Rosewood Wa Handle

The octagonal rosewood handle offers excellent balance and a comfortable grip while maintaining the lightweight feel that Japanese petty knives are known for.

Combined with the natural wood ferrule, it creates a clean, traditional appearance that complements the handcrafted blade.

Caring for Carbon Steel

This knife features a high-carbon steel core and is not stainless.

To keep it performing at its best:

• Wipe the blade dry immediately after use.
• Never leave it wet or dirty.
• Avoid dishwashers.
• Store it completely dry.

Over time, the blade will naturally develop a protective patina. This is completely normal and one of the characteristics many enthusiasts appreciate about carbon steel knives.

Complete Your Setup

We recommend pairing this knife with:

• Japanese whetstone for sharpening
• Leather strop for maintaining the edge
• Magnetic knife holder or saya for safe storage
• End-grain cutting board to protect the cutting edge
