The chisel would have the same chemical composition all the way through. I wonder if you're confusing hardening with tempering? Hardening means heating and then quickly cooling (quenching). Tempering is reducing the hardness by baking in a controlled manner, so that a balance of hardness and toughness is achieved. (That's my version anyway; there are smiths here who can explain it better.)

If you have access to a propane torch, you could probably heat and quench the tip to harden it for durability.

In shop when I was in school all of the projects was to make a cold chissle out of a piece of rolled steel, shape and harden the cutting surface, the grade was pass or fail, when you finished our teacher would take a nail and lay it on the anvil and then use your new chisle to cut it in half, if it cut the nail without damaging the chisle edge you passed, if it made any indention in the edge you failed and started over. one fella had hardened to far up the shaft of the chisle and when the nail was cut it also broke the chistle. The reason your punch is not hardened all the way to the end is it would be like that one fellas and brake, the softer steel alows it to absorbe energy both when being hit and the equal reaction from the object being cut.
we hardened the edge by cooling it in used motor oul after heating it.
All of the following truths are shameless lies. But what about this tiny ad:
