Paint scraping with the traditional triangular scraper is a tiring job causing hazardous forces and high wrist moments (Van Rhijn & Eikhout, 1998). As an answer to those problems the recently developed scraper has been designed with the end user in mind. This paper reviews a field study testing the new product with 20 professional painters. The results show that the new scraper, in comparison with the traditional one, has strong positive effects on physical load: wrist moments and forces are reduced. Furthermore, the new paint scraper was considered very user-friendly by professionals and ergonomic experts.
