My DGS each have a Bosch workbench (okay, I admit, I bought them for Christmas). No chainsaws, but a plastic drill, hammer, screwdriver, pliers, nuts and bolts, and saw. They're sturdy enough and they get a lot of play out of them, wearing their high vis tabards and hard hats. My DD2 suggested they'd like them after they'd moved house and their little one had been fascinated by all the DIY going on around him. I don't think myself that they'd be tempted to try dad's drill after using theirs, any more than they'd reach for the electric iron, kettle or blender after playing with their toy kitchens. They wouldn't get the chance anyway! The only worrying aspect is how keen they both are to saw off mine and grandad's legs....
