I've made a better cavalery lance.

I have made it look like the spear I saw on a drawing of a stradioto (albanian cavalerist serving venetia), but it might work for any cavalry. I haven't managed to find any photos of spearheads or spearheels from 16th or 17th century though, so I'm not sure how correct it is.
I had the impression that a spearhead was juist painted on a rectangular surface.
