From what I have heard of the steel there should be no disappointments. I can think back to a summer where I was given the privilege of running a jackhammer all day in the summer in Houston TX. I had wrung my t shirt out 7 times before 8:30 am. The bit was never in question on the hammer. The next day I was a noodle. Impact it can take. I want to know how it takes an edge and hold it. I am looking at this to replace a hatchet, axe, and a saw for moose hunting. I can afford to loose the weight!!!
