Brand

SDI has been famous for manufacturing pencil knives since its founding in 1953. Under the brand name "Hand", SDI gained a nation-wide reputation for quality and innovation.

Later, we started to market our products with the SDI brand all over the world and achieved great success with the passing decades. Our products include markers, staplers, correction tapes, cutter knives, clips and (electric) pencil sharpeners, and also no matter the self-owned brand, ODM or OEM is all popular in the domestic and foreign market.

Not only does SDI obtain patents on products, it also wins international design awards such as iF in Germany, Good Design in Japan, and Golden Pin in Taiwan. In the future, SDI will keep on developing more sharper, durable, and more professional cutters.
