Weapon Creation System

[Weirdbob95]

I like the concept alot!
Seems like an easy use, but I think you are missing Martial Weapons..? No?
Also, Powerful Criticals seems dangerously good to me. If you also take feats to increase your threat range then well...

Thanks!
Sorry if it wasn't clear, weapons are by default One-Handed Martial Weapons until you change them to something else. I'll edit the OP to try to make it more clear.
Powerful Criticals lets you increase the threat range from 19-20 to 18-20. It lets you create weapons similar to the kukri, rapier, and falchion in the SRD here:

Taking feats and other abilities to increase your threat range is still a powerful strategy, but I don't think it's any stronger than normal D&D.
