Hatsukokoro Ryuhyo SG2 Damascus Petty 150mm with Olive Wood Handle

Overview

The Hatsukokoro Ryuhyo SG2 Damascus Petty 150mm with Olive Wood Handle is a compact Japanese utility knife built for precision, speed, and everyday convenience. “Ryuhyo” translates to “flowing ice,” a fitting name for the clean movement of the Damascus pattern and the smooth cutting feel of the blade. At 150mm, this petty is ideal for trimming proteins, slicing fruit, mincing garlic, peeling, detail prep, and smaller board work where a gyuto may feel too large.

At the core is SG2 powder stainless steel, a high-performance stainless steel known for excellent edge retention, fine grain structure, and the ability to take a very sharp edge. The stainless Damascus cladding adds visual depth while keeping maintenance approachable for home cooks and professionals. The olive wood octagonal wa handle gives the knife a warm, refined look with a comfortable and balanced feel in hand.

This is a strong choice for cooks who want a premium Japanese petty knife that feels nimble, sharp, and easy to maintain. It works especially well as a companion to a gyuto, santoku, or bunka when you need more control for small ingredients and detailed prep.

Common Questions

Q: What is a 150mm petty knife best used for?

A: A 150mm petty is best for small and medium prep tasks like slicing fruit, trimming meat, cutting herbs, mincing garlic, peeling produce, and working with smaller ingredients on a cutting board. It gives more control than a full-size chef knife while still offering more reach than a short paring knife.

Q: Is the Hatsukokoro Ryuhyo SG2 Petty good for home cooks?

A: Yes. The SG2 stainless core gives excellent edge retention without the extra rust concerns of carbon steel, making this knife very approachable for serious home cooks. It should still be hand washed, dried immediately, and used only on knife-friendly cutting surfaces.

Q: How do I care for an SG2 Damascus Japanese petty knife?

A: Hand wash and dry the knife after use, avoid the dishwasher, and do not cut frozen food, bones, hard squash, or other dense items. For best edge life, use a wood, rubber, or Hasegawa Pro cutting board and maintain the edge with light stropping between sharpenings.
