Manufactured by Yoshida Metal Industry Co., Ltd., Koo Ryoji is a tableware knife manufacturer in Niigata Prefecture, Japan, famous for Western-style cutlery knives, which began to enter the international market in 1985 and is now one of the major Japanese kitchen knife brands that have entered the European and American markets. Although it is not as well-known in the European and American markets as Makusaku, Gu Liangji has a wide consumer base in the Japanese domestic market, and the real-time sales data of Amazon and Rakuten Market in Japan show that Gu Liangji's kitchen knives have long occupied the top ten best-selling lists.
 
Ryoji's kitchen knives are mostly made of CROMOVA 18 stainless steel, the hardness can reach 56-58HRC, although the hardness is not high, but its cutting method improves the sharpness, the cutting angle is only 15 degrees, the general kitchen knife will be between 16 degrees and 20 degrees, CATRA (British Tableware Joint Trade Study) cutting test shows that the original sharpness of the blade of the knife is higher than that of mainstream brands such as Xun, Trifurcation and Zwilling people.
 
Compared with the VG-10 steel kitchen knife, the advantage of Goyoji is that while ensuring sharpness, the toughness of the blade is also better, so the durability of the blade is more prominent, and it is not easy to break the slightly hard ingredients in daily use. However, Ryoji has poor sharpness retention, is easy to dull, needs grinding and maintenance, and its comprehensive performance is not as good as Tojiro.
 
The handle and blade are mostly one-piece structure, the handle and blade are made of stainless steel, the overall appearance design is more distinctive, and most of the knife types are lightweight.
 
In addition to a variety of basic knife types, there are also a variety of small kitchen knives. Commonly used knife types are concentrated in the classic G series, there are 43 basic models, you can choose according to actual needs, if you only want to choose a multi-purpose knife, we recommend the G2 chef's knife and G46 Santoku knife, these two are also the most concerned product models of Gu Liangji.
