I've been using this saw blade for about 3 months now. I don't use my saw every day, but I usually use it a few times when I have to. I've carved everything from aluminum to heat treated 13-8 stainless steel to aluminium-nickel-bronze alloy with it and it still works well. Though I'll take care of my blades. I move at the appropriate speed while feeding and use blade wax on hard metals. Pretty decent blade I'd say. It even suffered from a little abuse I'd subjected it to when I accidentally twisted it. I lost a tooth but it didn't break and I've been cutting hardened stainless steel with it ever since.
