Like the title says, what is the toughest, most indestructible saw ever built? Whatever it is, I NEED ONE! Guy that works for me bucking logs on the yard could tear up and anvil with a rubber hammer! He needs something with no anti vibe, no springs, no bushings, nothing except a rock solid design that he cant break in half! I don't care if it weighs 50 lbs and only has a chain speed of 200 rpms, he has GOT to stop tearing stuff up!
