Amazingly durable saw blade. Hardware stores don't usually sell this - this is a special order if you can get it at all. Why is that when it lasts 10 times (no exaggeration) longer than the "hardcover" version (even the Olson brand)? Well, just count - 10 regular blades - repeat sales - just under $200 OR 1 of these for the price of a blade. This is the same situation as with cobalt drills compared to everything else; buy one or buy 10.Hmmmm. Sounds like a no-brainer for me, for you OR the hardware store, whichever route you take.
