I resaw 8" and 6" ash, oak, maple and LOTS of cedar. I can easily re-saw 24 lineal feet of each of the hardwoods before the blades starts to wonder. I then , with that same blade, re-saw cedar for about 200 lineal feet before any problem. I also use this blade for many cuts other than re-sawing and it works fine for that, indefinitely it seems. I change out to a new blade when I next need to re-saw hardwoods again. I use many of these blades per year because I am working in my workshop forty hours a week.
