This toy has been in daily use by our three-year-old grandson who takes it everywhere. It contains a plastic claw hammer, one end of which is for baning in the plastic 'nails', and the other end, the claw, can be used for removing them, just as in real life. The adjustable plastic spanner can be used to fit round the nuts and can tighten or loosen them. The screwdriver actually turns the screws clockwise to tighten or anti-clockwise to loosen. These tools have been very useful for the child to learn new manual skills as well as vocabulary. The saw makes a 'sawing' noise when used against the side of the plastic workbench (but obviously it doesn't cut!) The only tool which doesn't seem so useful, apart from making a pleasantly grating noise, is the set square with centimetres marked on one side and inches on the other.
The tools have proved very durable. The only thing I'd like improved, if possible, is the 'catch' on the toolbox itself which is sometimes difficult to close and open even for me as an adult!
