Everything in life is a, "consumable", even us. Most of our American companies have meant their own ruination! Go back and read about the history of Nicholson File. It was a proud American heritage story but, even they cousumed another company to come out on top. http://www.charleswbullock.com/Guide/IndustryHistry/NicholsonFile/NicholsonFile.html To think where they are today, I am sure some of the founders of that proud heritage, would roll over in their graves, if someone gave them a Nicholson file today! These major companies such as Home Depot and Lowes have their own line and it is touted as a "Lifetime Warranty". You want to know why! It is a marketing gimmick with calulated risk. The average consumer is never going to bring it back at all. And if someone does make them live up to the "Lifetime Warranty" they are willing to do that, because that is not the norm!! Big companies have been taking calulated risks for many years. They use ingredients that they know are cancer causing. Why, because their product is cheaper to make using that often known cancer causing ingredient, from the get-go!!!. So they roll the dice and say well,............ we are gonna kill of X amount of people but the sales will give us a cushion if we ever have to pay out for the human lives that will be lost because. Whaaaaaaaaaaaaaat! If you knowingly kill someone in the real world, that can be considered Manslaughter of Second Degree Murder. However when the big companies do it, they face lawsuits and more often than not no one is ever held accountable!!! All the money in the world does not bring back even one life!! To the big companies, it is just the cost of doing business! Did you ever wonder why a huge company such as Dupoint blew out their name and all the profits they made under that name. Dupoint has been put on the hook for cancer causing teflon, among a few other products. They knew allmost immediately that it was cancer causing, But they rolled the dice and when it came down to time to pay the piper! Low and behold Dupoint has little to no assets and a company known as Axalta was born. A seperate enity of the old Dupoint but on paper it can not be touched for the sins of Dupoint!!! The company is quetly settling lawsuits to keep out of the news and when the money is gone and they no longer have to money to pay claims. Well it is all over and Dupoint will officially be dead! Tough luck if you came to table to late!! Look at Sears and what they have done and, it is about to cost them! A company that partenered with and eventually consumed Roebuck, and a company that was consemed by a company coming out of bankruptcy Kmart. They still take back some tools but Craftsman is a seperate entity, and they are being made in China. The old Craftsman rachets I have, will outlast me. The newer ones I have returned many times because they are crap!! OK, I am off my soap box but, believe this those companies that make consumables that get dull, when they have enough they will stop honoring their warranties. For now they will ride that calulated risk as far as they can!!!
