Ideas PLEASE????? Totally clueless.?

My son is 19 mths old. For his grandparents we made a frosty fingers ornament. However he has 7 uncles (ages 21-8) that are buying for him. Any ideas that I can make for them?? They're all mechanics and farmers. I don't want a pointless handprinted cars or something. I want something they can KEEP and USE. PREFERABLE with a handprint or footprint on it.... PLEASE HELP!!!!!
