Improving weapons and armours

[Sobel]

I thought about a system where you can improve your normal weapons like this:

you have a regular Steel Sword....so you can iprove it like this:
-Normal Steel Sword
-Sharped Steel Sword
-(need name^^) Steel Sword

And the same with armour:
-Normal Vaegir Armour
-Hardened Vaegir Armour
-(need name again^^) Vaegir Armour

If you want to improve weapons you must be blacksmith and for armor armorsmith.
And I think it would be much better if you would need Hardmode items to upgrade the stuff.

Please tell me what you think about it =D
