Swap Amazon for Harbor Freight and I can add a ton to this list.

Harbor Freight is actually a decent place to shop for tools like that...quality is very good and if there is ever an issue HF takes it back/exchanges without a problem. Kind of like the Sears of old before they went toes-up.

Harbor Freight is my jam.

The air nailer/stapler combo for doing trim/baseboards in your house or ground braid/GI sockets, or the wide crown stapler for running new ground braid:

Evaporust - I put that shit on everything! I am working on a couple of 80s machines like Classic Bally, Classic Stern they always have some rusty parts.

IMHO for $50 two Amazon tools not made in China are more valuable than a shopping cart full of Harbor Freight tools. Gotta admit my magnet grabber is only 8" or so so I could probably find use for that longer grabber somebody posted.

I just got theses a little while back and I must say they are the best works great and great price too good buy

The PZ-58 is the greatest tool ever made!F56C5B8D-663D-4D73-9075-443E976C5E86 (resized).jpeg

All the Japanese made Engineer brand stuff is extremely good! They make a lot of unique and useful tools.

And finally, what I think is the best thing I ever bought: https://www.harborfreight.com/3-in-1-convertible-hand-truck-56409.html
I bought mine from Costco for $99, but they no longer carry it.

Thought of this thread today when I used Engineer PZ-59 gripping pliers to take a stripped nut off my positive battery cable - no socket, wrench, vise grip , standard plier was gonna do this job and the PZ-59 just needed a little bit of material to get a grip and it spun right off. Funny thing, I was almost at the point of cutting the bolt before remembering these were in the tool box.

I got mine at Costco when they were on sale for $79! Best $79 I've ever spent in this hobby, hand down. That 45º setting is so absolutely perfect for moving pins, it's insane.
