A very useful technique is to case harden the bottom tool with kasenite case hardening compound. This can extend the life of a tool you are hammering hot steel into generally past your lifetime. It is inexpensive and a pound of it lasts a good long time.
To use, form the tool to your specification, heat to cherry/orange, sprinkle kasenite on, be aware it can smell like you sprinkled a dead mouse on it. Let it crust up then bring the piece back up to temp, cherry to dull orange. Plunge into cold water. often there is a loud pop or bang as steam blows the coating off. This makes the most of inexpensive and easy to forge mild steel.
