About the OP's original posted question:
I have had to write some warranty ad copy for vintage auto parts catalogs, etc, for my clients over a long career of that type of work. The real point of a "Lifetime LIMITED Warranty" is that the company is stating that there are ANY kinds of limits to their warranty implied. I'm no lawyer, but attorneys were consulted by my clients when that kind of copy was being written. I learned that if there are no limits to a warranty, then people can try to hold the mfr responsible for all kinds of "semi-related" things, such as gas money for driving the broken tool back to the retailer for replacement, "lost time" while the tool is out of service, cost of some other brand of replacement tool, etc. In other words (as I understand it), if there were no limits on a lifetime warranty, then the mfr is liable to be held financially responsible for ALL KINDS of costs. So, if a company plans to put ANY limitations on a warranty, then they need to put copy like, "Lifetime LIMITED Warranty" on their package and sales literature. Also, keep in mind that there are different consumer laws in every different state and country around the world, so manufacturers face a bewildering set of different laws. They must try to write warranty information that will protect them to some degree in many different sales environments.
You cannot blame manufacturers for trying to protect themselves from ridiculous claims. On the other hand, when you choose to buy one brand of tool instead of another, you are making that decision based on all the information available to you at the time of purchase. One bit of information which might lead you to choose one particular brand over the other might indeed be a "Lifetime Limited Warranty". And then you SHOULD really be covered by warranty service.
In the final analysis, the written warranty is not the real issue anyway. It's how they treat you when you try to return a tool. Perhaps more importantly, we all know that a retailer like Home Depot is not under the control of a manufacturer, like Husky for example (IE: Husky cannot force HD to cheerfully replace Husky tools under warranty. More likely, Husky sales people had to kiss HD's a$$ just to get HD to buy and reselll Husky tools). So for me, the real proof of Husky's warranty would be in what happens if I break a Husky tool, and call Husky's own customer service and ask for a replacement. THEN how will they treat me?
At that point, you CAN judge both the manufacturer and their warranty.
