Sheet metal in automotive repair is the process of restoring a deformed body to its original shape using various tools. This work relies on human skills, there are individual differences in skill levels, and it takes a lot of time to learn. The purpose of this study is to support the smooth acquisition of skills in sheet metal repair work. In this paper, we focus on the handling of the tools used in sheet metal work, which are dollys and hammers. The relationship between the force of gripping a tool and the movement of a hammer during work was examined to elucidate the skills of expert workers. As a result, the experts found that the hammer moved an almost constant distances and the gripping force did not change much during the work. But non-experts, the gripping force were not constant, they had changed a lot during the work.
