Cuts VERY well and makes a nice clean hole and outside on the removed cylinder BUT . Pulling the log cylinder out of the cutter is a REAL pain. The claim that side slits help the process is just a marketing joke. You have to push the rod through the holes in the top of the cutter to push the cylinder out and even then it's difficult because the cut is so precise and the cylinder is so clean it fits the cutter very snugly. very well made and looks like it will last a long time.
