Further Refinements

After analyzing the results of the evaluation methods we have reached to the following refinements for our tool EasyTrim:

EasyTrim should have a non-stick blade

Using a normal steel blade allows for non-clear and accurate cuts since the blade got easily stuck in the branch mainly due to dirt from the cuttings. This required more strength from the elderly to be used, as well as a greater amount of pressure on their wrist. Replacing the normal blade with a non-stick blade will reduce the pressure exerted on the wrist, as well as the strength needed to operate the tool.
