I am doing this merely for the pleasure of building my own tools.
In that case you will be successful. In your favor you have tools to compare to if your product compares favorably. It would be desirable if you could locate someone with a hardness tester to provide accurate feedback. Many machine shops have them.
Tempering is the difficult part. Achieving a known, uniform temperature environment for this step is the hard part. On Forged in Fire the blades always harden successfully. When they fail it is a result of failure at the tempering step.
