Fathers Day

Any ideas on what to get my father in law for Father's Day?? We're not super close but since my SO and I have moved out together things have been good. Many people are scared of their mother in laws but my father in law is definitely more intimidating. I don't have tons of money but I don't know what to get him. We usually do small gifts. I got my MIL a bottle of wine and flowers for Mother's Day but I'm stumped now.
