Yamada Kogyosho Hand-Hammered Frying Pan, 28cm Diameter, 48cm Including Handle Weight: 1578g, Plate Thickness: 2.3mm, With Instruction Manual If using with IH, please read the sixth photo before purchasing. Used for several years in a home, it could be said to be dirty, but the oil has become well-seasoned, resulting in a pan that has been "broken in." If you are concerned, you can re-season the entire pan by burning off the dirt and then applying oil, which will make it like new. Please refer to the instruction manual in the third photo. In the case of household gas stoves with sensors, the temperature may rise and the gas may shut off, making it impossible to season the pan. After use, heating it lightly to evaporate the moisture will prevent rust. The frying pans made by Yamada Kogyosho using the hand-hammering method are made by hammering thousands of times. They are durable and become better with oil the more you use them, making them the perfect professional-grade pan for grilling and stir-frying over high heat. 2 seconds ago
