Screwdrivers for me almost define functionality yet very few people know the correct way to use one, or if there is truly a correct method of using one in the first place. Developing the form of the srewdriver handle through prototyping resulted in it being comfortable as well as grippable. User testing played a key role in understang how people were applying force through the handle and subsiquently has alowed them to use the screwdriver for longer periods of time with significently less discomfort. User research provided me with some very useful insights into the methods people used to fix a screw and retieve it again. This reseach lead me to incorporate a surface that could be used as a light hammer for creating a small pilot hole, minimising injurs because of the screw slipping. Also including a free spining end positioned in the palm of the hand proved very helpful in speeding up the time it took the extraxt a screw from a piece of wood.
