The steel in old computer printers is very straight and usually good grade. Might be worth heat treating with a bit of Kasenit? - for long punches?
Also High tensile bolts turn down with carbide tooling and can make good small punches of short length- eg the "starter punch" pictured.
As for cold chisels, probably best to buy a reasonable set. CTC tools in HK do nice collets etc might be worth a look for hand tools? They're a good bunch to deal with too.
