Start with the round and square taper punch, hot and cold chisel, and hardy, then you can punch your tongs, then with your punch and tongs you can make a hammer etc... It is simply a progression of making tools to make other tools. Their are plenty of videos available online- I recommend the ones by Alec Steele, Brian Brazeal or ABANA.
Good luck...
That is if you want to make tools, some want to make tools others just want to but them and get started making "stuff"...
