One item I haven’t seen listed that I could no longer live without is my 71" tamper bar. It weighs an ungodly amount but I have used it to pry up pavers, rocks and stumps, break up hard ground, cut roots, dig post holes, jimmy out broken posts, shift logs, and poke at bonfires. Afterwards I feel like I’ve spent time pounding weights at the gym but it gets the job done and nothing else really fits the bill. I love my power tools but this thing is as basic as one can get…it’s just a big, pointy, metal stick.
We are retired — DH STILL has a bracket car that he has built 90% of that car himself ---- in a workshop 30 feet from the horse barn ---- that means we have acquired more “stuff” than what is reasonable for every imaginable and unimaginable occasion:).
So, all I have sitting on the barn counter is a pair of scissors and a pair channel locks — channel locks come in handy for a myriad of things they aren’t supposed to come in handy for — plus they bail out my arthritic hands just opening a simple lid anyone without arthritis can easily open:)
