Neko, one of the reasons Detroit cars were better than foreign cars was that you could fix anything with one screwdriver and pliers, no special service
tools needed. (Yeah, I know, that never was quite true.)
These days you need inch, metric, six point, twelve point, thin wall, deep, seems like there is always a need for another special wrench. Oh, and a number of vendors on Amazon are selling thread pitch
gauges which apparently are unlabeled but WHITWORTH not SAE or Metric.
ViceGrip, ChannelLock, Stinson wrench...
Yeah, those metrinch sound like they'd be more useful than one dogbone wrench or one Leatherman tool. Will they have shortcomings, sure, but isn't that why we all keep Sears on speed dial?
FWIW I think you can get a nice titanium wrench and jack from Ferrari...some folks know how to keep tools light.<VBG> Then there's the market in used beryllium-copper tools. Honest. The dust from them is toxic, but they're spark-proof for use in explosive vapor areas, apparently a little less durable than steel
, which is why they get sold off as surplus.
