In Taiwan, where the society is becoming an aging one, the products especially designed for the seniors are beginning to thrive. The purpose of this study is to re-design the clippers for the seniors and verify after reviewing the ones in market. Through observation and interviews, the early stages of the study’s first period evaluated 5 clippers in the market claimed to be especially designed for the seniors. During second period of the study, via experiments, magnifying nail clippers, slant nail clippers, and nail clippers with rotary bit – the ones for the seniors – are found to be not favorable to the users. From the point of view of human factor engineering as well as universal design, it is found that the seniors prefer the clippers with enough sharpness, require less effort, and good to be held. Furthermore, the study identified that the seniors are found to be not only unstable but even shaking while holding and pressing the clippers with non-dominant hand. With the experimental questionnaire of existing products and interviews, below key points for design are generalized: (1) effort -saving, (2) sharp (3) stable for holding (4) comfortable (5) interchangeable for both hands. The third stage is to re-design the nail clippers. SNAIL has auxiliary finger ring which is able to rotate. During the changing motions of clipping nails, the auxiliary finger ring decreases the seniors’ effort by providing a support point for the hand to increase stability, reduces the shaking resulted from holding and pressing the clippers. The handle is surfaced with rubber to provide more slip-resistance. The result recognized the fact that comparing to the nail clippers in market, SNAIL is better on the feeling of effort, holding, comfort, satisfaction as well as usefulness for both hands. Therefore, the efficiency of the seniors’ clipping their finger nails with nail clippers are promoted. However, the promotion on efficiency was not found on clipping toe nails.
