Ergonomics is the applied science of designing products that will maximise efficiency, whilst at the same time lessen user fatigue and discomfort. Ergonomic products are efficient in 4 ways:
They lessen the effort required to use the product
They are designed to be more comfortable to hold and use
They reduce the number of steps in a task so that it takes less time for the user to complete that task
They have fewer parts, making repairs and maintenance more straightforward
Ergonomic tools lessen the effects that using non-ergonomic tools would have on your body.
Ergonomic scrapers increase efficiency in a number of ways:
Firstly, they are lighter than other scrapers so they may be used with just one hand. They are made of non-slip, non-conductive and compressible materials, so that they are more comfortable to use.
Some have textured rubber handles which provide a good grip and reduce the effort needed to use the tool effectively. These handles ensure good grip even when the scraper is wet.
This particular scraper has a smaller blade which makes it useful for scraping small, difficult-to-reach areas. The black ball at the top of the handle allows for two-handed use, making the tool easier to use.
