In those days, they were large sharpeners that were placed on the tops of desks. Especially the JUPITER was favoured by Offices and Companies. Around the World War II they were equipped with an eraser. Since they were for daily use, they were very small and easy to manufacture. Nowadays, they can be bought in several sizes, made of various materials and in a large range of prices, but mostly they are made of plastic and come from China, Japan, or Korea.据我所知，削铅笔机起源于1900年。那时候的削铅笔机都特别大，一般都放在桌子上面，最受办
