I am cutting 3" thick poplar. I wasn't strict with the blade. We walked slowly and methodically. Lots and lots of rough edges where the blades seem to "jump" instead of cutting straight. Maybe me, I don't know, but it requires a lot of looping. Went pretty straight and broke. Given their prices, I think I'll experiment with an Olsen or two. A Timber Wolk can buy almost two Olsens. Time will tell but knowing it broke so quickly is a huge disappointment.
