I have a 72in finish mower i was going to sharpen the blades again after i ended up mowing over some metal earlier today. I got 2 out of 3 blades off the center blade i used my air impact rated at 1,500 ft lb. penetrating oil used map gas to heat it, sheared a 1/2 in drive torque wrench, standard wrench slips. Is there anything left worth trying. I'm considering getting a torque multiplier to see if it will get it. It's a 24mm bolt.
