The "Iron Flower Series" is a specialized sharpening stone developed by our company, a manufacturer of whetstones under the CHERRY brand, which has gathered years of expertise in whetstone production. We confidently present this sharpening stone specifically designed for knife sharpening. ◎ Confident in Grinding Power It allows for beautiful sharpening with light pressure, reducing working time, making it recommended for busy individuals. We invite you to experience the difference! ◎ Rich Variety We offer four types: Zaku-to (rough stone), Saku-to (medium stone), Spatto-to (finishing stone), and Pika-to (polishing stone). Progress from rough to medium to finishing stone, and for those seeking an even more beautiful finish, we recommend the polishing stone at the end. Beginners in knife sharpening should start with the medium stone, and if you want to elevate your skills, using the rough or finishing stones is also recommended. ◎ High-Quality Made in Japan We use high-quality abrasive grains based on JIS standards, produced and inspected carefully by craftsmen. It has good water absorption and provides a smooth sharpening experience. The series name "Iron Flower" is derived from the flower-like patterns that appear when sharpening with a stone that has strong grinding power. We have inherited the traditional technique of Tosa forged knives, which has been passed down for 400 years, and we received feedback during development from "Sakoda Hamono," a specialized knife workshop that is committed to forging. They have used our product in knife sharpening and have given it high praise.

"Diamond Paste WITH (oil-based)" finishes to a mirror surface in the final polishing process. Our diamond paste comes in a wide variety, with numerous options available in particle sizes ranging from 1/4μ to 90μ. Since diamond paste consists of diamond abrasives and a paste-like compound, the abrasives move freely without being fixed. Therefore, the pressure applied does not transfer directly, preventing deep scratches. By using it in conjunction with our mold grinding stones, you can achieve greater efficiency.

The product we are introducing this time is the diamond precision cutting wheel SACUTTER. It is developed for hard and brittle materials that are difficult to cut with conventional cutting wheels, making it ideal for cutting and grooving hard alloys, glass, ceramics, and more. It excels in cutting performance and processing accuracy, and we highly recommend you give it a try.

In particular, gloss is essential for the quality of plastic products. To create that quality, high precision molds are necessary for producing plastic products. The final polishing process is finished with diamond paste. ▼ Mechanism of Diamond Paste Polishing Conventional grinding wheels have abrasive particles fixed with a bond, so the applied pressure directly translates into grinding force, resulting in deep scratches. However, diamond paste consists of diamond abrasive particles and a paste-like compound, allowing the particles to move freely without being fixed. Therefore, the applied pressure is not transmitted directly, preventing deep scratches. Additionally, the depth of scratches varies depending on what is used to apply pressure. For instance, using a hard object like a bamboo spatula versus a soft material like felt will obviously result in different pressures transmitted to the abrasive particles, leading to variations in the finished surface.

The product we would like to introduce from our main product line of mold grinding stones is the product called "YHS." This is a grinding stone that has sulfur impregnated into a WA grinding stone. By adhering sulfur to the pore walls of the grinding stone, it can prevent grinding marks on molds. It has a moderate strength retention of sulfur, making it less likely to break and excellent in workability. Additionally, the lubricating effect of sulfur improves the surface roughness of the mold and significantly reduces the wear of the grinding stone. The hardness of the grinding stone is of type "I." (Note) As it is a flammable solid, please ensure that the grinding stone is dried naturally. It may cause a fire.

The product we would like to introduce from our main product line of mold grinding wheels is the 'YHB-T'. This is a ceramic grinding wheel for rough to medium finishing, which is impregnated with high-fracture-resistance phenolic resin in WA grinding wheels, and it is the strongest product in the YH series. It provides a smooth finish when cutting and removing the altered layer of materials after machining or electrical discharge machining, especially when surface roughness is a priority. Additionally, due to its strength, it is less likely to break during roughing operations under load or when working with small-sized grinding wheels. However, it tends to clog easily in dry conditions, so please use it wet. We recommend "BLUE CUT" from our company. The hardness of the grinding wheels comes in three types: "L" (hard), "J" (medium), and "H" (soft). Currently, we are offering free samples, so please feel free to contact us for more details!! ↓↓↓
