Adam,
Glad to see that you are taking the critique and advise in the tone it was intended. The sword is not bad , as first swords go.....looks wise. It is, however, a SSO (sword shaped object). I truly believe that with some research and planning, you can build a real sword from 5160,1070, or a similar steel. You now know that hardware store steel is mild steel and not blade steel. Learning about carbon content and alloying will help with the selection. Read Kevin's posts and go to his site to learn a lot about the metallurgy of blade steel.
The handle is sort of simple, but that is not a fatal flaw. Using some better material (maple, micarta, etc.) and pins of brass or steel will make it a little better.
The grinds looked very nice.
I will make you the same deal that I offer to many other new makers.
Read up on the subject of knife making. Do some research. Make a plan for your next project ( a knife would be more advisable). Hook up with a local maker if at all possible. When you feel you are ready to get started, post a thread about the project with all the info, plans , sketches, and intended procedures. The folks here will help you fine tune the process. I will send you a box with the proper steel , first class handle materials, and some other supplies to get you off on the right track.
How about it?
Stacy
