Review on Keystone Demolition Klein Tools 602 4DD by Erik Snyder

I've used a cheap flat head screwdriver as a hammer for years and it has held up well. I decided to replace it with Klein 602-4DD as that's what it was made for. From the Klein website: Designed, manufactured and tested to break and chisel. Coated metal percussion cap to protect the handle from hammer blows. A heat-treated metal rod runs the full length of the handle to the metal percussion cap to transmit the force of the metal strike. this is primarily for that. Installation of retaining rings, installation of container clamps on iron girders and other work involving a bat, except for concrete or other unusual violations. The tip has already been deformed and a small piece of it is left. Didn't last very long and wasn't actually designed, manufactured or tested for cracking and chipping. While the strike is a great idea I'll give it two stars but for now I'll buy a whia demo and see if it stands up to the challenge of demo work.
