This technically belongs in games, but I've found it useful enough out here. It's a paid(I think) Steam game with a demo. It is called 'bladesong,' and it has really helped me make weapons for my world. It is singlehandedly the most flexible blademaking game I have ever seen, and it provides you with lots of customizable parts. In fact, the community, in the EARLY ACCESS SESSIONS, made a FORKLIFT. It has separate tabs for the hilt and blade, materials to make them, and some really handy parts you can customize. Check it out!
