I used run a small chain of sporting goods stores and because Walmart and others were able to undersell the smaller retailers, the rumor started going around that they sold inferior products. However, it was only an Urban Legend. 1] In fact, often Walmart would sell products cheaper than the dealers could buy them from the wholesalers. Walmart is notorious for requiring special pricing from manufacturers, which manufacturers often found themselves suffering from as a result. 2] It is not in the best interest of ANY manufacturer to cut corners on their products as more people become familiar with them through the venue of stores like Walmart. 3] Often, people would buy from WM and come into our stores to trade for something else. Unless it was special made from WM, we could not tell the difference. Walmart does get products made to different specifications, such as wooden stocks, etc. but they also get the normal products.
As for Buck, a number of years ago Buck started having quality control problems and also having knives made in China. Even the American products were defective. They, then, sold these products to not only Walmart, where more people experienced them, but also to the small mom and pop shops. This was not unique to Buck. Many companies went through this during those years. I remember seeing Colt Single Actions without the cylinders being bored through, or bored at an angle, for instance. Today, Buck makes great products, are moving their products home to American, and I would not hesitate to buy from Walmart or my favorite knife online store.
