For me, it's the farm jack. I think I spent about $29 for it, with coupon, about 14 years ago. I have used it to: Lift my neighbor's docks out of the mud and get it floating. Lift another neighbor's decrepit dock from the water onto land. Lift my dock ramp up a 4' embankment. Fix a boat trailer flat on I-85 on a holiday weekend. Lift a shed. Change tires on my tractor. Remove fence posts. And a lot of other things I'm forgetting. Still works as good as the day I bought it. Hall of Famer HF tool.
