Knowing how to improvise an arrowhead could come in handy, I only listed the tools below that you would need to make this by hand. You could easily use a cutting disc or bench grinder to make this arrowhead also.

Tools Required:

Hammer

Hack Saw

Tin Snips

File

First you will need a spoon.

Next place the spoon on a flat surface and flatten with a hammer.

Next mark out the shape of the arrow and cut it with tin snips or hack saw.

Next sharpen the arrow with a file.

The last step is to cut off the handle of the spoon, making sure to leave enough to mount to your arrow.
