How to Make Arrowheads From Saw Blades
Making arrowheads out of old saw blades can be a rewarding hobby. As the arrowhead is formed, the practice becomes an art. Many people choose to make arrowheads out of used saw blades for several reasons. First, an old saw blade is a cheap way of getting the correct steel for the project. Also, you can shape the arrowhead into any design, shape, and size you like.
Things You'll Need

1
Clean an old saw blade thoroughly, grinding away rust with a belt sander or a grinder.
-
2
Cut out a cardboard pattern from dimensions you're planning to form your arrowhead, using scissors. Use the cardboard pattern as a guide and trace around its edges with a marker directly onto the saw blade. The pattern can also be drawn on the saw blade slightly larger than the dimensions you would like; this will make up for steel that will have to be sanded down.

Cut the arrowhead pattern out of the saw blade by using either a cutting torch or a high-powered Dremel tool. Grind any rough edges or torch marks off by using coarse sandpaper on a sanding belt or a grinder. Use a pair of pliers to hold the arrowhead as it is likely quite small and grinders have been known to injure fingers if they get caught.

4
Grind/sharpen the edges of your arrowhead, using a grinder. Run the arrowhead across the grinder in a steady, consistent motion to form the edge. Continue this process with finer sandpaper to make the arrowhead consistently smooth throughout its body.

5
Heat-treat/harden your arrowhead to the point that it glows red and then submerge it in tempering oil. Polish off any roughened surfaces with very fine sandpaper and a metal polish.
