i was given a pack of 3 punches buy a neighbour the other day...cheap blackspur crap...
tried the centre punch this morning to mark a few holes in basic mild steel and it lasted 4 dots before the end rounded off...
so, i re sharpened it with the grinder, got it glowing with the torch and dipped it in water, brought it back to a blue-ish colour and quenched again and now its far better...tested it out by just making random pop marks and 35 marks in and its still sharp...
Maybe this thread will help someone that has accidentally bought a cheap tool because it was all that was available...
