Frosty,
I have made chisels, crowbars, punches from sucker rod. I will post a photo this evening. I made a crow bar at a demonstration at our church Bible School last evening. I was not paying attention and got the bend backwards!!!! Sucker rod is easy to temper with just a quinch and you have it. the steel in the rod will draw the temper from the tip of the chisel or crowbar. It is hard to forge but make rally tough tools. These are some of the objects I have forged
piece of sucker rod at top. My personal forged hammer included with a poorly done crowbar.
