Don't restrict yourself to the most common tool brands. Everywhere I've worked 90% of the common hand tools were Craftsman ,Snap On or trash tools. Fill your box with quality combo wrenches, sockets,ratchets etc. from Proto,Wright ,Williams etc. and use a little spray paint. The honest guys in your shop will learn who they belong to and will go out of their way to return them. Most good mechanics are honest and helpful. The dishonest guys ,you will quickly learn to identify and will have to keep your guard up. Nobody ever accidentally mixed up my Proto combo wrenches or Wright ratchets or sockets with their stuff. Don't worry to much about the "Truck Guy" warranties, most good tools can be warrantied with a little effort.
