This chainsaw is a must in any children's workshop! It is an exact replica of a Bosch design from Theo Klein, and is an almost perfect copy of its big sister ' when the saw blade is used, the saw makes a realistic sawing noise and a flashing light indicates that the saw is working hard. of course it all looks as realistic as possible ' the saw blades can even be changed ' but the saw is completely safe to use. The idea is simply for budding young workers to have lots of fun and to give them the feeling they are doing real jobs, just like the grown-ups. Children learn a lot from these kind of role play games ' particularly when they are working alongside their parents, who can show them how to use tools safely whilst they are playing, with this saw and many of the other tools from Klein.
