HF stepped drill bits.
Very pleasantly surprised with them.
Possibly cheap by most professionals' standards, but my Craftsman 3/8-drive flex head ratchet with the black handle grip lives in my hand when I'm in the shop. I've used and abused it for ten years.
A small 6-inch Craftsman nail-puller/pry-bar. It's thin, it's small, and it gets a lot of use. I think it was $1.99.
Finally, a small ball peen hammer... it was free from my grandma's house when she died. Little head, small metal handle about 6 or 8 inches long, with a knurled area for a hand grip. It's my most used hammer. It'll move big things if you need it to, but it'll move small stubborn things without breaking them. It applies finger-pressure force, when your fingers aren't supplying enough force.
I handed it to my friend one day while working on getting a bellhousing separated from an engine. He was pissed and said "Hand me a real hammer!" I said "get started with that one while I go get another."
"um... hey... this little thing is actually working pretty well..."
I bought him and my other buddy each one, when I found a pair for sale here.
