i got some 30mm rebar in the workshop and i wanna try making some hammers from it

i cant see to find anything about using it for this only people making tongs knives and spears

I've used 1/4" for blades before but i have no idea about using 30mm

the punches are just normal old center punches and are 25mm diameter

we dont have much for heat treating we got oxy torches and im bringing my forge from home

the steel is 4140

my metals class is making some cromoly punches and need advice on heat treating
