Yu Kurosaki trained under famed blacksmith Hiroshi Kato at Kanehiro Uchi Hamono in Echizen, and has spent over two decades building one of the most distinctive catalogs in Japanese knife making. His lines span wildly different aesthetics and steels - but the common thread is a convex grind that becomes nearly imperceptible at the edge, producing a knife that is athletic in character: equally capable cutting hard dense produce and gliding through soft onions. The Senko Ei line is SG2 powdered stainless at 62 HRC with san mai stainless cladding, rosewood octagonal handle, and the Senko surface treatment that gives the line its visual identity.
The 120mm petty is the most compact knife in the Senko Ei line - short, light, and built for the tight linework that a longer blade cannot manage cleanly. Arturo runs a ramen shop and uses both the 120mm and 150mm Senko pettys during service - calling them professional knives made and finished right. He notes the short length means a dropped knife hits the handle rather than the tip, an honest practical observation from a professional who works them hard. At 2.4 oz and 29mm height this is a precise, nimble detail knife. SG2 at 62 HRC holds a keen edge through sustained service without reactive maintenance. Even 50/50 double-bevel grind works equally well for right- and left-handed cooks. Free US shipping over $100.
What Customers Are Saying: One five-star review from Arturo, chef at a ramen shop. He and his team run both the 120mm and 150mm Senko pettys through service day and night. He calls them professional knives made and finished right, and recommends the 120mm specifically for newer line cooks - noting the short length means a dropped knife hits the handle rather than the tip. A practical endorsement from someone who has tested this knife under real professional conditions.
Care Instructions: SG2 is a fully stainless powdered steel - low maintenance and resistant to corrosion. Hand wash and dry after each use. Avoid the dishwasher. Use wood or rubber cutting boards. Avoid bones, frozen foods, and hard materials. Sharpen on quality water stones - SG2 at 62 HRC rewards a consistent angle and light pressure. Strop regularly between sharpenings. The convex grind benefits from a flat stone used with light, consistent pressure to maintain the geometry.

Kurosaki makes beautiful knives, and a privilege to work with. This specific knife is short and suitable for linework specialy for a newby. Since this knive is short and light, it will usually fall to the floor hitting the handle and not the tip. We use 120mm and 150mm kurosaki senkos, at our ramen shop day and night... this are professional knives, made and finished right. I will recommend this knife for serious line cooks.
