So I used my CS Gurkha Kukri at my grandparents' house to help them with some trees, ranging from 4" to 5.5", And in less than half an hour I downed 4 trees with it, I didn't tire, and the only problem I had was my left hand got cramped. The cramping was unrelated to the project. After I cut them down I dragged them a couple hundred feet or so and burned them. And to help the fire I then went into a thickety area and took some old knotty logs from a stack and split them without a baton, (I really didn't expect that to happen) and the only damage sustained was from hitting the dirt once, and the damage were a couple chips I had to really look for, a few strokes on ceramic took care of that. All in all it preformed 10/10.
