Uh huh. Regardless of whether you or 1950mercury approve of using sarcasm to make a point, I told the OP to upgrade the most fundamental tools.
Do you disagree with upgrading any of the tool categories I mentioned? Do you actually have any advice for the OP?
Advice would depend upon what the OP already has... lol. I would say most people cheap out on screwdrivers when first getting their tool collection started, so that would be my first choice, along with allen and torx bits / keys / whatever.
Ratcheting wrenches are also awesome as well, so if you have standard wrenches, getting ones that ratchet are a big benefit.
I have a full set of craftsman sockets, standard, metric, and impact for 3/8 and 1/2. I don't see a need to upgrade from them at all. If the sockets fit, what else is to be gained?
I would also say tool box. I love having a bigger tool box. It allows all my tools to be neatly displayed, making it easy for me to find exactly what I am looking for, and to find what is missing. It just makes the experience easier and more enjoyable. Though I am a hobbiest.
