Kurosaki Petty from the Senko line is another special blade from the hands of a talented young master blacksmith, Yu Kurosaki. The knife features a distinctive hammer pattern, offset blade and SG2 powder steel. The unique triangle shaped hammer imprints on the top part of the blade resemble a dazzling diamond pattern − hence the name SENKO, which means "eternity" in Japanese. This is a great knife to own and use while marvelling at the amazing skills of the young master blacksmith.
A must-have in every kitchen, this small general-purpose knife is used for peeling and slicing fruit and vegetables, while its compact size and a relatively narrow blade also makes it very nimble and thus perfect for filleting fish, cutting poultry, slicing smaller pieces of dry meats and trimming meat.
→ The Ei series has a lowered and slightly offset blade in relation to the handle. The advantage of this design is that it has a greater knuckle-clearance. The size and shape also allow for stand-alone and versatile use.
→ The pronounced “K-tip” proves very useful with fine, decorative work with vegetables and fruit, as well as with trimming and skinning, as it’s great for piercing through the skin.
→ The blade is 150mm (5.9") long.
The octagonal handle is made from beautiful, dark rosewood that is rounded off with a maple ferrule. It fits comfortably in the hands of both left- and right-handed users.
The core of the knife is made of R2/SG2 powder steel that is hardened to around 62-63 HRC and two layers of a softer stainless steel protect the core steel. R2 is a high-quality steel that is easy to maintain and sharpen and retains edge for a long time.
The steel is laminated, meaning that the core is made of very strong steel covered with an external layer of softer stainless steel − also known as san-mai clad.

It has a double bevel (symmetrical) blade (50/50). The blade has a V-edge profile, which means that the blade tapers all the way from the spine to the edge on both sides at a common angle.This kind of grind offeres a good balance between the ease of cutting and robustness.
The subtle combination of the migaki polished finish and the triangular hammer impressions is the hallmark of Kurosaki knives. The textured blade* ensures that food does not stick to the blade, and thanks to the unique shape of the pattern, the blacksmith has ensured that the light from the blade glistens as if from a water surface.
*the hammer marks are made with a special hammer with a triangular structure

ABOUT THE BLACKSMITH:
Yu Kurosaki is a young, talented master blacksmith who lives in Takefu Knife Village, close to the city of Echizen. His knives are well known throughout Japan and also around the world for their beautiful, unique-looking design and superior quality. Hammer's dents on the blade are his signature finish, and just like with snowflakes, not a single dent is alike. Needless to say (but we will say it anyway), his knives don’t only look great but they’re also made of high-quality steel and have a razor sharp, long-lasting edge.
Before opening his own smithy, Kurosaki-san was the apprentice of Hiroshi Kato, a master blacksmith with more than 50 years of knife-making experience. Kato-san is one of the founders of Takefu Knife Village, where now more than 10 master blacksmiths make knives by hand and put them on display for visitors to admire and learn more about their craft. Kurosaki-san is the youngest blacksmith to be granted the title of Master Nokaji by Takefu Knife Village Association and is a senior teacher there.

Blade wear depends on the quality of steel, usage and maintenance of the blade. Japanese knives are made of high-quality steels. Follow these tips to keep your Japanese knife in top-notch shape:
✔ Use a wooden, plastic or rubber cutting board.
✔ After use, wash the knives and wipe them dry.
✔ For storage, use a knife holder or a protective knife sheath (saya).
✔ A good cutting technique is your best bet to prolong sharpness.
✔ Use sharpening stones to sharpen the knife.
❗️Don’t leave the knife in the sink. Wash it by hand.
❗️Don’t wash the knife in the dishwasher.
❗️Don’t use the knife on glass, ceramics, marble or steel surfaces.
❗️Don’t scrape the food off the cutting board with the edge of the blade. Use the spine of the knife instead.
❗️Knife is a tool intended for specific use - cutting food. It is not a can opener, screwdriver, trowel, wire cutter, hammer etc.
