Don't skimp on driving tools such as hex keys and Torx drivers, and also consider them as expendable items; when they show wear sharpen or replace them. European brands such as Wiha and Bondhus seem to have better steel and workmanship. You can get a little more life out of hex drivers by grinding the worn ends down until new, sharp edges are exposed. But replacing them is cheap compared to the cost of damaged components. Shiny chrome or cadmium plating is usually a giveaway to low quality.

Get a good pair of cable cutters; the Park ones are OK but the best by far are Felco. They cost more but are worth it, I have never regretted the money I spent on them. I have had mine for decades and they are as good as the day I bought them.
