The battery pliers are still useful, lots of half inch nuts still being used on battery clamps. The red pliers are very similar to a group of tools that Matco tools was marketing 10=12 years ago, pliers and screwdrivers, but the pliers all had rubber grips. That tiny MAC bit holder is, I believe from a small kit that they sold 15-20 years ago, anyway that is the bell that rings for me. MAC often marketed tools in their montly special handouts, that were not in their tool catalogs.
