The screwdriver was purchased for use around the house (including the assembly and disassembly of small pieces of furniture as well as the drilling of thin wooden and metal structures). When I handed it over to the builders to use, I was taken aback when I discovered that they had attached screws (40 mm for wood) to it in order to construct sleeping bunk beds out of wood for themselves. Absolutely delighted with the transaction; the quality more than deserves the cost.
