Here is my everyday user set. The box is Proto, but the tools are mostly Proto Challenger with some Proto and other brands mixed in. Mostly metric with the ignition wrenches being SAE. Most everything these days is metric, so I opted for putting together a vintage set for today’s use. It was cobbled together from stray tools in the garage, garage sales, swap meets, and eBay. Don’t know what the cost was to put it together as it evolved over a long timeframe, but it works for me and is all American made.
