Here's a pretty simple way to produce a good quality arrowhead, fairly quickly and without too much difficulty.
This is everything I used to make mine:
A shell casing
(Note: It needs to be of fair size. I started out with a .22 and it proved to be too small. I ended up using a .223/5.56 casing, 30/06, .308 should work just as well.), Wire cutters, A File, Patience,Wooden Arrow (I used a practice arrow), Pocket knife, Pliers, And some carpenters glue.
Step 1: Remove the Primer From the Shell
Its much easier said than done, but not at all a sisyphean task. Ok, this is where the file and patience come in.
File About an 1/8in above the extractor groove. The brass isn't extremely hard and with perseverance and patience the primer will come right off.
