Lowes now (as of earlier this year) is selling a line of Mechanics Tools called
Kobalt which is made by
Snap-On. They are good tool
Home Depot's Husky brand is made by Stanley Mechanics Tools, a division of the Stanley Works. Husky are also good tools and have a good lifetime warranty (they'll even replace your broken Craftsman with an equivalent Husky).
Until 1994 or so, Stanley also made Sears Craftsman tools.
Sears Craftsman is now made by Danaher Tools. They beat out
Stanley on the contract over price.
Danaher also manufactures MatCo Tools, the third largest player in the Mobile Automotive industry (behind MAC and Snap-On). Odds are, if you own any Craftsman tools that are older than about five years ago, they were made by Stanley in plants in Dallas, Texas, Witchita Falls, Texas, and Sabina, Ohio.
Stanley also owns MAC Tools and manufactures MAC tools in the same plants. Now here's the kicker: MAC Tools,
Proto Tools (a very expensive industrial brand), Husky Tools, and, (prior to five or so years ago) Craftsman Tools are all made from the same forgings in the same plants. Proto is unique because it goes through addtional testing and certification because it is used by NASA, the military, and industrial customers (including General Motors).
There are three MAJOR players in the USA mechanics tool business:
Stanley, Danaher, and Snap-On. Stanley and Danaher (almost identical in sales revenue at about $28 billion each) are the biggest followed by Snap-On. Each of these three manufacture and sell tools under a variety of brands (there are many other brands that Stanley makes that I haven't even named). The quality between these three manufacturers is roughly the same. I know its a bit of a let-down to hear that, but its a simple fact.
There are a hand full of other minor players (Vermont American, etc) and an endless list of Taiwanese import tool companies (some of which Stanley own as well as Danaher to serve the lower end consumer import brands at WalMart, etc). How do I know all of this? I work for Stanley Mechanics Tools, specifically with the Proto Industrial brand. I personally do not think that MAC, MatCo, or Snap-On branded tools are worth the extra markup since they use the same forgings and manufacturing processes that make Husky and Kobalt and pre-1994 Craftsman. Where you need to pay attention are things like ratchets and torque wrenches. There are different specifications of ratchets and you do pay for the difference. Some mechanics require a finer, more precise ratcheting mechanism than guys like me who just bang around in the garage on the weekends.
By the way, Metwrench is basically considered a "gimick" infomercial tool brand that is not considered as a serious competitor to Danaher, Snap-On, or Stanley. Then again, IBM once didn't see Microsoft as a serious force in the personal computer business. Hmmmm....
