Now ya tell me, lol. I do have an air chisel but it didn't occur to me to use it. Originally, I tried busting it up with the jackhammer, but it was taking forever and the concrete was just pulverizing. Yes, using that sledge was a ton of work, but I was able to get out some pent up aggression, so I got a neat little therapy session out of it.
