I think my dad have a complete set of power tools. But my mom stills ask to buy for the best new tools for dad. I know that he will be happy. This site gave me the best information: www.squidoo.com/best-new-tools-dad
Of course some of the tools when not used properly, they tend to break or it some parts may be damaged. My dad loves to fix things and as a birthday gift i will give him a complete set of top new tools for dad.:)
