people born with one arm, patients suffering from stroke and temporary injuries often face difficulties when using with daily objects due to the limitations of one functioning hand. Traditional pencil sharpener requires both hands to operate, which is unfriendly to one-armed people. Inspired by the design of household rotary mop, we devised pencil sharpener SPIN for one-armed people. To use it, the user may insert the pencil into the cutter head and press it down vertically. The built-in spiral mechanism would convert the downward force into rotational one which spins the pencil sharpener.
