What present to get for my dad?

I need some ideas for gifts to get my dad for his birthday. I was going to get him hockey tickets to see his favorite team, but no longer have the funds. He doesn't have alot of space for trinkets. I know he loves pistachio's and word searches, but already bought him a bunch for christmas... he's an electrician... that's about it if you have some good idea's that would be great. I want to get him something that he will truly like otherwise he will just throw it away... Thanks! :)
