The best birthday gift for anyone, dad included, is one that conveys genuine thoughtfulness. It is sometimes hard to buy for the man who seems to have everything, however, thinking creatively helps in finding a great birthday gift.
Tools make a great gift for a man who likes to fix or build things, and there is a vast array of tool kits that make an affordable and thoughtful birthday gift. For a dad that likes to relax and chill out, consider a Zen sand garden to be put on a desk at work or in a home office. The sports-loving father might really appreciate a set of glasses with the logo of his favorite sports team or a picture of the stadium in which the team plays.
