Spear head and sheath

[Taffjones]

Hello everybody decided to come out of the shadows(where i have been lurking for sometime) and have a go at posting.
Have had this item in my collection for some time. Could anybody help me identify it please and maybe give it a bit of a critique please. Some of the questions I would like answered if possible

1. What is it
2. Where does it come from
3. What materials is it made from
4. Is it new/old or somewhere in between
5. Is it a tourist grade item or intended for indigenous use

Thanks
