I have been using mine to chop down small trees. So far the biggest was about 8 inches in diameter. And I’m talking hardwood(white oak, red oak) not pine. Ive hammered it through pecan and hickory with heavy beating on the tip. I’ve stabbed into a piece of cedar and twisted repeatedly to make a hole. I have not seen any damage whatsoever to the SRK in SK5 All production knives will have a few defective examples.
