You can do something wrong for 40 years and you're still doing it wrong.
In your on/off, black/white, ultra-conservative, inexperienced by-the-book opinion supporting the needless disposal of perfectly good items in the interest of CYA, perhaps yes.
I brought in my bar and a chain for the man to check out. I thought I needed a new bar. He said maybe but not until he checked things out for me. He began inspecting my old stuff. He opened some new chains, tried a couple of them on my bar and offered me my options. I asked him for his recommendation. He said my chain had maybe one sharpen left in it and the drive links were worn. He said my bar and nose sprocket were perfectly good and evenly worn. Too small for a .063 chain but a perfect fit for a .058. He said it's silly to buy a new bar and new chains when all I needed was new chains. He said the old bar would more than likely be just fine for the life of the new chains but if not, he had another bar for me. That was his recommendation. As always, I accepted and appreciated the benefit of his experience.
This may not fit your wallyworld replace-me-now attitude but you know what? With the more aggressive RS blade, the saw works better than it ever did and I have every confidence that it will continue to do so. What may be totally improper to people like you is nothing but business as usual for others of a more practical nature. You don't succeed in business in a small southern town for that many years by giving valued customers bad or unsafe advice. Be careful who you're calling an idiot.
PS: He's the same dealer that said I didn't need to buy the silly bike handled model of Stihl brushcutter to run Maxi blades as long as I used the handydandy safety harness he gave me with the machine he recommended. He also said I didn't need to buy the top-of-the-line solid shaft model because when I broke the drive cable in the model he suggested, he would replace it for free and would continue doing so for as long as I owned the machine. Indeed, after two years of rough usage, he replaced one cable and I haven't cut off my leg.
