In 1953, Mr. Shui-Chin Chen founded “Shuen Der Manufacturing Company” to make Hand-brand pencil knives
The “SDI’s Pencil Knife” was the first iteration of the SDI Master Knife. It was created in 1953 and was the first pencil knife made in Taiwan.
Post-war shortages even in everyday necessities meant that even knife blades had to be imported as there wasn’t even a “metal processing industry.”
The conditions at the time meant that scrap metal from canned foods was stamped to make knife handles. The different patterns on the early knife handles were the result of these cans. Later on, recycled beer cans were also used as a source of metallic materials.
